Even the best of us have miscalculated and run low on battery before heading to an outlet, but that's what external battery packs are for. These devices pop up on sale from time to time, and today there's a good deal on the Poweradd Pilot X5 with a 16,000mAh capacity. The price usually hovers around $40, but you can score one for $24.99 with Prime shipping using the coupon code below.
There may not always be a power outlet nearby when you need one, so perhaps a giant external battery is something you should consider. In fact, there's a particularly massive battery from EC Technology on sale through Amazon right now. 22,400mAh of power for just $34.99.
This device is usually priced between $50 and $55, so this is a solid deal. It has two USB ports (up to 2.1A) and an LED flashlight for good measure.
Now that everyone seems to be carrying around smartwatches, Bluetooth headphones, and various other bits of electronic detritus, we need ways to keep them charged up when they inevitably die before the end of a long day. Samsung wants your Galaxy phone or tablet to be the backup battery for other stuff, like a Gear watch, via the brand new Power Sharing Cable. It's a little double-sided MicroUSB cable that allows one gadget to charge another, without any AC adapter or portable battery pack.
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.
You can never have enough battery power, especially when you're traveling. A handy flashlight and a fancy LCD for management don't hurt either. If you're in the market for an external battery pack, Woot has an especially big one on sale today: a massive 16800mAh portable charger from Gorilla Gadgets. You can pick it up for $39.99 plus Woot's usual $5 shipping, which is $30 off the same product on Amazon.
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...
