There are absolutely no shortage of battery case offerings for iPhone 6. Even though we’ve covered the best iPhone battery cases here,
it’s sometimes overwhelming sorting through them all. The real winners
are the ones with maximum battery capacity and some extra features to
spice things up. Recently, I came across Dyconn’s i6 Power Case
and was pleasantly surprised to find that it fits most of what I was
looking for, but is it enough? Well, not only does this case pack a
3,200 mAh battery inside, it also features wireless charging. It’s not a
must-have feature, but I sure do appreciate the convenience…
When I first received the case, the packaging wasn’t too flashy (a
bit basic in my opinion), but I was more interested in the
features/functionality. With 3,200 mAh, you can almost charge up an
iPhone 6 twice. That was definitely appealing. On top of that, being
able to recharge the whole package wirelessly means that I don’t need to
shuffle around for my cable.
Inside of the box, you’ll find a Micro USB charging cable, headphone
jack adapter, the case’s dock (for charging), and the i6 Power Case.
It’s a pretty simple setup overall. There are pins on the bottom of the
case that correspond to small plates on the dock. When these points
connect, the case/iPhone begin to charge. It’s not Qi charging, but for
the ease of use the conductive wireless charging will do just fine.
Watch the video review for a full demo of this feature.
The dock features its own fixed USB cable that can be plugged into your
iPhone’s wall adapter for power. If you’re not in the mood for wireless
charging, the Micro USB cable can be used with the port on the bottom
for charging/sycing, but the iPhone will not sync through the wireless
charging dock if plugged into a computer for power. Also, it’s important
to note that the 3.5mm jack adapter may be necessary for certain types
of headphones. Earpods fit within the recessed headphone jack just fine,
but for anything wider you’ll need to keep track of that adapter.
The i6 Power Case is made from Polycarbonate and TPU with full
protection for the iPhone. The side walls of the case are flexible (TPU)
and allow you to slide in the iPhone without having to worry about
disassembling anything. It provides a very secure fit and the rubber
coating on the outside of the case feels good in the hand. If there’s
one thing I’m not a fan of here, it’s going to be the rubbery matte
finish. It feels great, but picks up prints and oils from your fingers
very easily, thought that’s no different from most other battery cases.
The i6 Power Case is surprisingly thin as well, only adding 1/4″ to the
overall bulk of the device and about a half inch in height.
The lock/volume buttons are covered, but the case provides openings for
the camera/flash and mute switch. On the backside of the case, there’s a
small power button that will illuminate LED power indicators above it
when pressed. If you hold down the button for two seconds it will begin
charging the iPhone, an additional two second press will cut the power.
As far as recharging goes, the instructions notes that it will take
roughly 3.5 hours to fully charge the iPhone with its case and we found
that to be accurate
Overall, you can’t go wrong with this battery case. It’s simple,
provides a good amount of extra battery life, and features wireless
charging. You also have the ability to purchase additional docks ($24.99)
if you’d like to have more than one around the house or a spare for the
office. If you’re interested in the whole package, you can pick up the
MFI-certified Dyconn i6 Power Case (dock included) for $89.99. When compared to other battery cases on the market, it seems like a pretty good deal.

Huawei Honor 4X review: Multi-day battery life ahoy
Here’s a smartphone category that is right now molten--the
enticing 10K price barrier. From the smartphone stalwarts to the young
upstarts, its a maelstrom of products that are vying for attention.
Irrespective of your choice, the basic requirements for the
overwhelming majority of cellphone users are fairly defined: a battery
that lasts at least a full working day, a reasonably sharp screen, and a
camera that takes decent photos. Anything else is icing. These days,
the entry level has been unarguably set at Rs 7,000 (well, Rs 6,999
precisely)--both the Moto E and the Redmi 2
are at it tooth and nail here, with several other brands snapping at
their heels. Then there’s Rs 10,000 price limit, which is where things
get interesting: the variation in features of phones at this price is
surprisingly wide. Some tilt the scales toward better gaming
performance, some offer heightened battery life, while others manage to
pack slightly larger and higher resolution screens. There’s something
for everyone.
Which brings us to the Huawei (pronounced “who-ah-weigh”) Honor 4X
that was launched last week along with its bigger sibling the Honor 6
Plus (of course the latter is cocking a snook at Apple’s flagship
phone). The Honor 4X is priced at Rs 10,499 and is a 5.5-inch dual SIM
LTE phone. Much like Xiaomi’s Redmi Note 4G--in fact they’re virtually
identical in specification--this one is characterized by a hefty battery
and is otherwise powered by mainstream-level hardware: an ideal formula
for a device that offers prolonged battery life with decent performance for everyday tasks. Let’s step up and look closer.
At a resolution of 720 x 1280 pixel, this phone’s 5.5-inch
screen is nowhere near retinal display: it packs about 267 pixels per
inch, a level where an average person cannot discern individual pixels
on screen. Also the visuals are surprisingly clean and crisp. Also
unlike other brands that are wont to bump up color saturation to make
images ‘pop’, this one was balanced, with excellent brightness and
contrast and natural colors.
The core hardware is mainstream level--the phone’s Snapdragon 410 based
platform makes no bones about this fact. But this new part is more power
efficient compared to its predecessor while featuring improvements in
processing efficiency, amply demonstrated as we used the phone. The
phone’s Emotion UI, which is a skinned version of Android 4.4.4 (monthly
updates are promised, though no word on Lollipop availability) packs
neat features such as launching common apps from the lock screen using
gestures and shortcut buttons, an on-screen button for quick access to
common controls and more. While there is 8GB of specified built-in
memory, only a shade over 4GB is available for use, which is a bit of a
downer. There is a microSD card, but which can take only a 32 GB card.
During extensive daily use consisting of always-on WiFi, 3G data,
continuous Bluetooth connectivity to a smartwatch and using a range of
web, productivity apps and gaming, the phone refused to drain even two
days being unplugged (see screenshot). This is unprecedented stuff. Its
3,000 mAH battery coupled with its power-efficient Snapdragon 410
hardware platform along with software-based optimizations (like when the
phone regularly notifies you of apps that are overly power-hungry) all
clearly do a spectacular job in translating into real-world endurance.
On the photo front, its 13 MP rear camera performed
reasonably well across scenarios, nothing to set it apart though. These
days features like ‘beauty enhancers’ and the like are all the rage;
unfortunately this phone succumbs and includes such gimmicks. I found
them all but useless, but they’re great for getting a kick out of. It
also has an ‘all-focus’ mode that lets you choose the focus point in
your photo after taking the shot. I found this feature worked
erratically--clearly it isn’t Lytro-level image processing, but appeared
to be some type of pseudo blur-applying algorithm. The panorama and HDR
modes did function as expected, and overall the camera was snappy to
respond, but overall the primary camera is very middling. The secondary
camera is 5MP, resulting in higher-resolution selfies, but is average so
far as front cameras go.
This phone is clearly optimized for staying alive between
charges, while delivering all the performance that general smartphone
use mandates. There are a few downsides like the fact that the battery
is fixed, so it isn’t user-changeable. But the ability to use a
smartphone without worrying about it dying out over the course of the
day is indeed refreshing. And when it lasts for over two days at this
price? It’s quite a breakthrough. For the 10K price brigade, the Honor
4X is a first among equals.
What we liked: Truly stellar battery life, sharp screen, good UI optimization and features
What we didn’t: Average camera, non-removable battery, 4GB of available internal memory and only up to 32 GB microSD cards supported

Review: Just Mobile TopGum portable charger for mobile devices
Okay, I could have gotten a paper copy of my boarding pass,
but after a day of GPS-assisted driving through Chicago (with my iPhone
attached to my rental car’s AC vent using my Spiderpodium),
my iPhone was DOA as I approached O’Hare, and I didn’t feel like
waiting in line. Without my Passbook pass, I’d be stuck waiting in line
with everybody else waiting to get a paper boarding pass.
Luckily I’ve had one of Just Mobile’s TopGum battery packs in my travel kit for a while, so my dead battery didn’t get in the way of my flight.
After dropping off my rental car, I was down to the dreaded 10% red battery zone. I grabbed the TopGum from my backpack, then switched my iPhone to airplane mode and plugged it in for the bus ride to the terminal. I was the last top, so by the time we reached the terminal I was nearer to 20%, which let me bypass the ticket counter line and straight on to security without the fear of my boarding pass vanishing if my iPhone died.
The other killer feature of the TopGum is its built-in Lightning cable. It tucks securely into place when not in use, but it’s flexible enough to bend and accommodate any iDevice—even my iPad in a stand case. The fast charge provided by this cable is great for iPhone 5S/6/6+ and iPad, as they take advantage of the higher output to charge faster. Just Mobile lists the TopGum as capable of charging an iPhone three times, and an iPad to 75%, so even dedicated conference callers or gamers should have enough juice.
Once I’d made it through security I went on to my gate, only to be greeted with the news that my flight was delayed. Since O’Hare still charges for their WiFi (one of many reasons I despise that airport), I went ahead and plugged my phone back into the TopGum and tethered it so I could kill some time. After two hours of use my iPhone was fully charged and the TopGum was only down to 50%, at which point my flight was finally ready to board. With everybody searching for plugs, it was nice to keep my seat and still be able to top up the battery.
The TopGum comes in black/silver or white/gold aluminum to match the colors of Apple’s latest devices, and it’s only $79.95. As one of the best-designed mobile battery packs I’ve tested, that price is amazing. Just Mobile’s focus on great design and functionality have combined into another winning piece of gear.

On the Bus
The TopGum is a sleek external battery pack with multiple charging options. First, to charge the TopGum’s battery you can use the built-in Micro USB port or pop it on the magnetic charging cradle. The cradle’s great to leave on your desk for charging, letting you grab the TopGum and throw it in a bag when you’re ready to head out the door. When you’re ready to use the TopGum, you can charge anything from the built-in USB port, or charge newer iDevices using the built-in Lightning cable for fast charging with its 2.4 amp output.After dropping off my rental car, I was down to the dreaded 10% red battery zone.

I was the last top, so by the time we reached the terminal I was nearer to 20%, which let me bypass the ticket counter line and straight on to security without the fear of my boarding pass vanishing if my iPhone died.
Not Cleared for Takeoff
All of Just Mobile’s products feature killer design, and we’ve said as much in reviews of their products here on TechnologyTell. The TopGum is no exception, and one of the features I truly came to appreciate is the heavily rounded corners. It sounds simple, but hear me out—the TopGum is much thicker than other battery packs, and at first I wondered at the design choice. However, those thinner batteries are always taller and wider, and therefore less convenient to throw in your pocket (for further reading, see Bendgate, Debacle of). The TopGum is the perfect size to fit in your hand, and its smooth brushed aluminum surface and gracefully rounded corners make it much easier to slip into the pocket of your jeans or a backpack without sharp corners to catch or a tall and brittle design that can easily break.The other killer feature of the TopGum is its built-in Lightning cable.

USB-C: What you need to know about Apple's newest port
Apple's new Retina MacBook comes with just one port – USB-C. Here's what you need to know about it and why it's important.
Apple's special media event last week wasn't solely focused on the
upcoming Apple Watch. Per usual, Apple had a few tricks up its sleeve.
Specifically, Apple surprised almost everyone when it introduced a new
and incredibly thin 12-inch Retina MacBook.
What makes Apple's new MacBook so fascinating is that it only comes with
one port – USB-C. Just one solitary USB port to rule them all, as many
people have jokingly characterized it. In other words, there's no
MagSafe, there's no Thunderbolt, and there are no additional USB ports.
All of the ports we've come to know and love are nowhere to be found on
Apple's new super light and stylish MacBook.
But just what is USB-C, exactly, and why are so many people exceedingly excited about its inclusion on the soon-to-be-released MacBook?
The answer is that USB-C may very well be the first Apple-inspired standard with mainstream appeal. Here's why.
First off, USB-C is fast. We're talking about theoretical speeds of 10Gbps, a throughput that would put it on par with the first iteration of Thunderbolt. And compared to USB 3, USB-C can transfer data twice as fast. Consequently, USB-C addresses one of MagSafe's limitations, namely that it was incapable of transferring data.
Second, and quite obviously, USB-C can transfer power. More importantly, it houses support for bi-directional power, meaning that a host device can charge a peripheral just as easily as a peripheral can charge a host device. Again, this is not something MagSafe can do.
Usability-wise, USB-C is great, borrowing some of the design elements of Apple's proprietary lighting port connector. Which is to say USB-C is entirely reverseable, thereby saving users the worry and hassle of accidentally plugging a cable in upside down. Additionally, USB-C cables look identical at both ends, so users will no longer have to worry which end of which cable goes into which device.
Size-wise, USB-C is extremely compact, measuring in at about the size of a micro USB.
Of course, the obvious question on people's minds with respect to USB-C is how they'll be able to go about their day-to-day computing with just one port. After all, it's not as if we live in a peripheral-less world.
Well, one of the defining features of USB-C is that it's a port of many, many talents. It can support DisplayPort, HDMI, USB, gigabit Ethernet, SD cards, VGA, and can even support 4K displays. Of course, utilizing a USB-C port for one of the aforementioned technologies requires a requisite adaptor, something which Apple and other third parties will only be too happy to sell you.
But more than anything, what makes USB-C an absolute home run for users, and for Apple, is that it's a completely open standard. MagSafe was undeniably an amazing Apple innovation, but it was proprietary and Apple was reluctant to let anyone even come close to copying it. USB-C, on the other hand, is open for everyone. Down the line, once USB-C becomes more ubiquitous, the ramifications will be apparent.
Right now we live in a world filled with endless types of cables. And frustratingly, only certain cables can charge certain devices. Because USB-C is universal, it will thankfully reduce the number of different cables people need to carry around. In other words, in a world where all PCs feature USB-C ports, swapping out charging cables with friends will be easier than ever.
Now, the downside to USB-C, as with any new transfer technology, is that it may take some time for the market to adapt. This means that in the interim, machines with USB-C ports will require adapters in order to interface with most peripherals. This is undoubtedly frustrating in the short term, but is really no different than the growing pains associated with any new technology. Just a few years ago, for example, iPhone users went through a similar ordeal when Apple replaced its iconic 30-pin connector with its new lightning port connector.
Another theoretical downside to USB-C is that, to be blunt, it's no MagSafe. MagSafe was great because it magnetically attached to a user's laptop. Whenever someone accidentally tripped over the cord, the MagSafe adapter would be ripped out, thereby preventing the laptop from tumbling to the floor. While Apple's new MacBook isn't MagSafe-compatible, this may be more of a theoretical problem than a practical problem. The thinking is that the MacBook, with its impressive battery life, may only need to be charged once in the morning to last throughout the day. And with 10 hours of battery life, it's certainly a compelling argument. Additionally, some have posited that the MacBook is so light that a MagSafe adaptor might easily pull a tethered laptop down to the ground with it.
Life With the MacBook’s Single Port Won’t Be Easy—Yet
Apple has a history of “addition by
subtraction” when it comes to ports and drives. It has over the years
ditched FireWire, Ethernet, and optical drives. Now, with the MacBook, it says goodbye to all but a lone pioneering port. This probably was inevitable. So just how big of an adjustment are you in for?
Bigger than you might realize. At least for now.
How we push data to and from our machines constantly evolves thanks to the steady progress of new standards, faster wireless connectivity, streaming services, and the cloud. Apple tends to anticipate these changes—and in some cases force the issue, often being among the first to banish old-guard tech from its devices. It’s been a successful strategy; just ask any phone with a physical keyboard.
But the new ultraportable MacBook doesn’t just nip an optical drive here and a FireWire port there. It cleans house. And while we’re accustomed to hermetically sealed, port-barren devices in our pockets and on our coffee tables, a laptop with plenty of connectivity options is part of what makes minimalism possible elsewhere. With the new MacBook, your “plug and play” options are a 3.5mm headphone port and a USB-C port—a standard that isn’t exactly swimming in compatible components just yet.
The good news is that USB-C is versatile. It’s a standard that, unlike the stalled Thunderbolt interface, will be embraced by many devices and peripherals that don’t originate in Cupertino. It’s capable, too; the port on the new MacBook can shuttle data at 5Gbps, it can charge and be charged by whatever it’s hooked up to, it supports video out, and it’s tiny. The only bad news about the shift to USB-C ports is the MacBook has one of them.
For those who need more I/O in their lives, Apple now sells its own USB-C adapters that let you turn that single port into a three-headed hydra supporting HDMI-out, full-size USB 3.1, and a passthrough for power. Another version swaps the HDMI-out port for VGA-out. They cost $79. Each. That’s more than an Apple TV.
And even those pricey dongles don’t come close to replicating the ports on a MacBook Air or MacBook Pro. The 13-inch Air has a dedicated power connector, a Thunderbolt 2 port, an SDXC card slot, two USB 3.0 ports, and a headphone jack. The 13-inch MacBook Pro has all of that, plus an additional Thunderbolt 2 port and HDMI-out.
Apple’s message is clear: You don’t need all those cables. It’s better to carry something that feels almost weightless, something elegant and slim and gold than have some pört-gåsbord weighing you down. “Besides,” Apple seems to insist, “you can address all of your needs via Web services, or streaming, or iCloud, or one of the wonderful new features we’ve added to Yosemite. Would you like more ports? Well, we have inelegant dongles and more-expensive computers for that.”
At some point, getting data and electricity to and from your MacBook with just one port may be seamless and natural. Today, though, we’re at least a few dongles away. Here’s how the MacBook plays out in practice.
Potentially easing the frustration is the fact that most modern cameras have built-in Wi-Fi features, so you can hypothetically leave your card in your camera, beam photos to your phone or a cloud service, and use it as a passthrough to your computer’s hard drive. That sort of set-up would be basically unworkable for pro photographers shuttling RAW files, though, and probably more trouble than it’s worth even when dealing with JPEG files in any quantity.
The same solutions and limitations apply to video editors. Videos taken with an iPhone can be magically ported to the machine via iCloud, Dropbox, or most other cloud services of your choice, so that’s easy enough. USB-C can handle video files zipping back and forth (through an adapter or new cable, for now). Other wireless transfer options aren’t very practical for files of the sizes you’ll be dealing with. The most likely setup for a wired-in connection will be a USB 3.0 or 3.1 cable running from a video-capture device through a dongle.
Meanwhile, the new MacBook will come with up to 512GB onboard, and cloud-storage services abound these days. That could be enough for most people, but anyone who’s been stashing years of valuable files and photos and music on an external drive would be inconvenienced by a MacBook today. To get the important stuff from there to your new machine, for the time being you’ll need an adapter.
Multi-port docks for the MacBook are likely on the way, but without that $79 add-on you won’t be able to simultaneously charge your laptop and work on a bigger screen or use a dual-monitor display. Or use a non-Bluetooth keyboard or mouse when your single port is occupied.
What may be the strangest USB-C fallout? If you want to mirror your laptop screen on your television, your cheapest and best option at this point is to buy an Apple TV. It costs $69 and supports AirPlay mirroring, while Apple’s HDMI-out multi-dongle will cost you $10 more.
There’s a reason, though, that Apple has put concerted effort in making Yosemite interact with iOS devices in wireless ways: Continuity, Handoff, and AirDrop are all geared toward seamless interoperability between its mobile and desktop OS, no literal strings attached. And here’s the big thing on the horizon: Future iOS devices will likely use USB-C as their one and only port, which will be an instant fix. Until then, you’ll need an adapter or an as-yet-unannounced cable to charge your iDevice from a MacBook.
Here’s a fun resulting fact. As of right now, it will be easier to charge an Android device with an Apple computer than to charge an iPhone or iPad with one—just as long as you have this upcoming $20 Belkin cable. Again, USB-C is a standard, and it’s one that will show up on many other devices, too, so don’t expect this to be an issue for long.
In many ways, this new MacBook is an exciting harbinger of a bright future, one teeming with interoperability and free of proprietary connectors. We’re not quite there yet, though. And until we are, it’s going to be a long, dongle-paved road.
Bigger than you might realize. At least for now.

Dangling Dongles
Of course, there are ways to compensate, though not as many as you might think. The cheapest, most direct way to get your usb cable devices to play nice with a USB-C port is a $19 USB-to-USB-C adapter from Apple (or this $13 model from Google, whose Chromebook Pixel features two USB-C ports). That’s a good start, but it still limits your choices to hooking up a single device or charging your laptop.For those who need more I/O in their lives, Apple now sells its own USB-C adapters that let you turn that single port into a three-headed hydra supporting HDMI-out, full-size USB 3.1, and a passthrough for power.

Photos and Video
If you use an iPhone for most photos and directly upload your shots to your iCloud photo library (or the cloud service of your choice), you’re set. But if you use one of those old-school “standalone” cameras and one of those dinosaur “SD” or “CompactFlash” cards, you’ll need to wait until somebody makes a card-to-USB-C adapter to get much use out of the MacBook. In the meantime, you could plug a USB card reader into a $13 or $19 or $79 adapter.Potentially easing the frustration is the fact that most modern cameras have built-in Wi-Fi features, so you can hypothetically leave your card in your camera, beam photos to your phone or a cloud service, and use it as a passthrough to your computer’s hard drive. That sort of set-up would be basically unworkable for pro photographers shuttling RAW files, though, and probably more trouble than it’s worth even when dealing with JPEG files in any quantity.
The same solutions and limitations apply to video editors. Videos taken with an iPhone can be magically ported to the machine via iCloud, Dropbox, or most other cloud services of your choice, so that’s easy enough. USB-C can handle video files zipping back and forth (through an adapter or new cable, for now). Other wireless transfer options aren’t very practical for files of the sizes you’ll be dealing with. The most likely setup for a wired-in connection will be a USB 3.0 or 3.1 cable running from a video-capture device through a dongle.
Storage
Your USB-C external hard drive options are non-existent right now, but help is on the way. This summer, SanDisk will offer a 32GB thumbdrive with USB-C and full-size USB connectors. A LaCie external drive will offer up to 2TB of portable USB-C-connected storage when it’s out later this year. End of list so far. But now that there’s a demand, the USB-C drive market will grow. You’ll have plenty of options if you hold out a few months.Meanwhile, the new MacBook will come with up to 512GB onboard, and cloud-storage services abound these days. That could be enough for most people, but anyone who’s been stashing years of valuable files and photos and music on an external drive would be inconvenienced by a MacBook today. To get the important stuff from there to your new machine, for the time being you’ll need an adapter.
Ethernet
While Apple already phased out Ethernet ports across its laptop lineup, there are a few cases in which having one generally comes in handy. If you’re dealing with crappy Wi-Fi service or that odd hotel that only offers jacked-in connectivity, yes, you’ll need a adapter for that. Belkin already has announced a USB-C-to-Gigabit-Ethernet adapter, but the pricing and release date are still a mystery.External Monitors and Video Output
Anyone who uses a laptop as a mobile machine and the docked guts of their home/office scenario will absolutely need to fork over for a dongle or avoid the new MacBook altogether. For now, at least.Multi-port docks for the MacBook are likely on the way, but without that $79 add-on you won’t be able to simultaneously charge your laptop and work on a bigger screen or use a dual-monitor display. Or use a non-Bluetooth keyboard or mouse when your single port is occupied.
What may be the strangest USB-C fallout? If you want to mirror your laptop screen on your television, your cheapest and best option at this point is to buy an Apple TV. It costs $69 and supports AirPlay mirroring, while Apple’s HDMI-out multi-dongle will cost you $10 more.
iOS Devices
Curiously—and this is bound to change soon—there doesn’t seem to be a way to charge your iPhone or Pad with the new MacBook without using an adapter. Apple hasn’t yet officially announced a Lightning-to-USB-C cable. For all we know, one may come in the MacBook box. Otherwise, for a wired connection, you’d have to use a dongle, plug the fat end of your Lightning cable into that, and charge or sync an iOS device with a cumbersome setup.There’s a reason, though, that Apple has put concerted effort in making Yosemite interact with iOS devices in wireless ways: Continuity, Handoff, and AirDrop are all geared toward seamless interoperability between its mobile and desktop OS, no literal strings attached. And here’s the big thing on the horizon: Future iOS devices will likely use USB-C as their one and only port, which will be an instant fix. Until then, you’ll need an adapter or an as-yet-unannounced cable to charge your iDevice from a MacBook.
Here’s a fun resulting fact. As of right now, it will be easier to charge an Android device with an Apple computer than to charge an iPhone or iPad with one—just as long as you have this upcoming $20 Belkin cable. Again, USB-C is a standard, and it’s one that will show up on many other devices, too, so don’t expect this to be an issue for long.
In many ways, this new MacBook is an exciting harbinger of a bright future, one teeming with interoperability and free of proprietary connectors. We’re not quite there yet, though. And until we are, it’s going to be a long, dongle-paved road.

USB-C vs. USB 3.1: What’s the difference?
With the launch of the Apple MacBook and Google’s Chromebook Pixel, USB-C (also called USB Type-C) and the accompanying USB 3.1 standard are both hitting market somewhat earlier than we initially expected. If you’re curious about the two standards and how they interact, we’ve dusted off and updated our guide to the upcoming technology. The situation is more nuanced than it’s been with previous USB standard updates — USB 3.1 and USB Type-C connectors may be arriving together on the new machines, but they aren’t joined at the hip the way you might think.
USB Type-C: Fixing an age-old problem
The near-universal frustration over attempts to connect USB devices to computers has been a staple of nerd humor and lampooned in various ways until Intel finally found a way to take the joke quantum.USB Type-C promises to solve this problem with a universal connector that’s also capable of twice the theoretical throughput of USB 3.0 and can provide far more power. That’s why Apple is pairing up Type-C and USB 3.1 to eliminate the power connector on the MacBook. It’s a goal we agree with, even if we’re less thrilled with the company’s decision to dump USB ports altogether with that single exception. Google’s approach, in providing two USB-C and two regular USB 3.0 ports, is obviously preferable, even though it adds a bit of bulk to the machine.
Type-C connectors will be shipped in a variety of passive adapters (an earlier version of this story erroneously asserted that such cables would not be available, Extremetech regrets the error). The spec provides for passive adapters with USB 3.0 / 3.1 on one end and USB Type-C on the other.
USB-C, USB 3.1 not always hooked together
The Type-C plug can be used with previous standards of USB, which means manufacturers don’t automatically have to adopt expensive 3.1 hardware if they want to include it in mobile devices. Apple, to be clear, is offering USB 3.1 on the new MacBook, though the company hasn’t disclosed which third party vendor is providing the actual chipset support.The disconnect between USB 3.1’s performance standard and the USB Type-C connector is going to inevitably cause confusion. One reason the shift from USB 2.0 to 3.0 was relatively painless is because coloring both the cables and plugs bright blue made it impossible to mistake one type of port for the other.
The upside to decoupling USB 3.1 from USB-C, however, is that companies can deploy the technology on mobile phones and tablets without needing to opt for interfaces that inevitably consume more power. Then again, some might argue that this would be a moot point — the USB controller can be powered down when it isn’t active, and when it is active, the device should be drawing power off the PC or charging port anyway. Heat dissipation could theoretically remain a concern — higher bandwidth inevitably means higher heat, and in devices built to 3-4W specifications, every tenth of a watt matters.
If I had to bet, I’d bet that the 100W power envelope on USB 3.1 will actually be of more practical value than the 10Gbps bandwidth capability. While it’s true that USB 3.1 will give external SSD enclosures more room to stretch their legs, the existing standard still allows conventional mechanical drives to run at full speed, while SSDs can hit about 80% of peak performance for desktop workloads. It might not be quite as good, but it’s a far cry from the days when using USB 2.0 for an external hard drive was achingly slow compared to SATA. Signal overhead is also expected to drop significantly, thanks to a switch to a 128-bit and 132-bit encoding scheme, similar to that used in PCI-Express 3.0.
The ability to provide 100W of power, as opposed to 10W, however, means that nearly every manufacturers could ditch clunky power bricks. There would still be concern about ensuring that connect points were sufficiently reinforced, but provided such concerns can be accounted for, the vast majority of laptops could switch over to the new standard. Hard drives and other external peripherals could all be powered by single wires, as could USB hubs for multiple devices.
The higher bandwidth is nice, and a major selling point, but the flippable connector and the power provisioning will likely make more difference in the day-to-day reality of life. As for competition with Intel’s Thunderbolt, USB 3.1 will continue to lag Intel’s high-speed standard, but as bandwidth rises this gap becomes increasingly academic. At this point, it’s the features USB doesn’t allow, like RAID and TRIM, that matter more than the raw bandwidth does in most cases.
Apple’s MacBook will be first out the door with USB 3.1 and USB-C support, with vendors scurrying to match the company on both counts. LaCie has announced a new revision of its Porsche Design Mobile Drive that takes advantage of the Type-C connector, but only offers USB 3.1. It’s going to take time for the 3.1 spec to really show up on peripheral devices, even those that adopt the USB-C cable. Motherboard support outside the Apple MacBook is probably 4-5 months away, though the first peripheral cables should be available well before that point.
