Technology in general and mobile tech in particular is on a rapid march forward, but there's a bottleneck that's holding it back: batteries. For years lithium-ion batteries have been the best option for storing energy pound-for-pound, but they've hit a wall - now we can only get bigger batteries or make our gadgets more efficient. A team of researchers at Stanford University have created what they call the "holy grail" of battery technology, a battery with a stable lithium anode.
Anker makes solid external batteries, and there's a nice deal on one of the larger ones over at Amazon right now. The Anker Astro E3 with 10,000mAh of juice can be yours for $25.99. This unit has a retail price of $80, but of course, you're never going to pay that. It usually bounces around $40, so this is still a good deal.
It seems like there are just never enough electrons in your phone, right? With just a few thousand milliampere-hour, it can be easy to drain your device before there's an outlet handy, so it's a good thing portable battery packs exist. If you're carrying something extra anyway, you might as well go big. A Crave Travel Pro 13,000mAh battery that should work nicely is on sale over at Amazon.
I don't know about you, but I always carry hammers in my pockets. So, clearly it's important I know how a smartphone will stand up to a hammer. Enter TechRax, who took it upon himself to do a hammer test on the Galaxy S5. The lesson we can all learn from this: don't hit high-density lithium-ion batteries with hammers. Just watch the very end... trust me.
The trend with external batteries is to make them smaller and more portable while packing in as much capacity as possible. The new second generation Anker Pro2 doesn't so much eschew that trend as it takes the capacity thing way to the extreme. This external battery has a whopping 20,000mAh capacity, which obviously impacts the size. Still, it's somewhat slim for having so much juice. Should you make the room?
As a technology obsessed individual (hey, you're the one reading an Android blog), you probably take things like external batteries and travel routers on trips. Well, there's a product that can take the place of multiple devices, and it's on sale. The HooToo TripMate Wireless N Router has a built-in battery to keep your devices juiced up and offers wireless access to USB storage. This thing is kind of like a mobile Swiss Army knife...
The Samsung Galaxy Note 3 is already a great big phone, but the ZeroLemon battery case for the Note 3 is finally here to make it even bigger. This rugged case packs a humungous 10,000mAh battery with NFC support. It also makes the phone into kind of a hideous brick, but that's the price you pay for insane battery life.
The case should be compatible with all versions of the Note 3 with standard or extended batteries already installed.
Most mobile devices will run out of juice before you do after heavy use, so external battery packs are sometimes a necessity. New Trent sells many such devices and has just announced a new one. The PowerPak Xtreme is a gigantic battery that's built to last. If only your phone was that rugged.
This device quietly went on sale a few weeks ago, but is only being made official today.
