External battery packs provide backup power, but with the way some phones routinely die every evening, you may come to depend on one as a regular source of supplemental energy instead. In such an instance, it helps to pick up one of the smaller options available. It's also nice if you can get one for under $10.
Fortunately, we've come across a KMASHI 10000mAh power bank that scratches both itches. It's going for $14 on Amazon, but if you enter the coupon code GOQL7EVL at checkout, you can drop $4.50 off the price. Read More
This KMASHI 20000mAh external battery is bright blue. That alone should be enough to distinguish it from the couple dozen other external battery packs you've picked up over the years. When the local power grid fails for an entire month, you will be the one guy in town whose smartphone is actually better charged now than it was before everything went dark.
Wait, what was I talking about? Right, there's an external battery pack available on Amazon for $30. Read More
External battery packs are nice to have lying around. They're one type of product where even if you already have one, it's good to have another. Who's going to complain about having too much backup power available?
So here's a cheap way to take your current number of battery packs and increase it by one. The HooToo Prism power bank is available on Amazon for $24, but with the use of coupon code E74NXWUD, you can strike that down in half. Read More
You have two options when you sign up for Project Fi. You can buy a SIM card with a new Nexus 6. Or you can just buy the SIM card and stick it in your own Nexus 6. Want to use another phone? You can, as long as you tether it to a Nexus 6. A Project Fi SIM has to go into a Nexus 6.
For the time being, that eliminates a sizable chunk of interested consumers. Read More
Removable batteries? Bah. External USB batteries? Child's play. Real power users use multiple batteries to make sure that their phones never turn off within a hundred miles of electricity. Or at least that seems to be the idea behind the M5, an upcoming smartphone from Chinese manufacturer Gionee. Read More
In a public presentation, Samsung has discussed some of the technical-oriented plans they have for the next few years. These can be summed up as all in the service of reducing the size of components and making them more efficient. Concrete goals include making batteries smaller but also more energy-dense, reducing charge time, and slimming down camera sensors.
According to their talk, their batteries now have a density of 700Wh/l (Watt-hour per liter). Read More

As we all know, Google I/O is right around the corner. So far this year, we haven't seen too many early clues as to what Google will cover in its keynote (though Ars Technica's I/O tracker is a great place to get some ideas) outside of its new Photos app, but we do expect that Google will be telling us about Android M (internally called macadamia nut cookie or MNC).
The specifics of what Android M will bring to the table are still a mystery, but we've heard a few things that could make this an exciting update. Read More
External batteries don't have to look good. They're big chunks of lithium-polymer wrapped in plastic and USB ports. But there's no reason that they shouldn't! Check out this Aukey 12000mAh battery, for example: nothing special, nothing fancy, just clean lines, a black case, and an obvious purpose. If you squint it kind of looks like an obelisk from 2001. Today Amazon has a coupon that drops the already-reasonable $24.99 price down to $17.99 - that's just .15 cents per milliamp-hour!
12KmAh should be enough to charge even the biggest phones three times over, with a bit of a margin for the inevitable efficiency drain. Read More
You never know when a backup battery might come in handy. You could be sitting there, recording your son giving the high school drama performance of his life when, all of a sudden, that low battery warning pops up. Filming HD video drained it faster than you thought, didn't it? Fortunately you bought that iClever Intocircuit 15,000mAh battery on Amazon. Or you will have bought it after reading this post, and your son's play is actually a week from now.
This pack provides 5V/3.1A output through two USB ports, there's a tiny LCD screen that tells you how much of a charge remains, and an LED flashlight comes included because why not? Read More
