KMASHI's 10000mAh external battery charger is slim enough that you can carry it around in your pocket and charge your phone at the same time, as long as you aren't bothered by the prospect of walking around with a little bulge. Last month we saw it available on Amazon for $9.50 after a coupon code. Now it's back, and by entering JAK3JCUV at checkout, you can get it for $9.40 instead. Read More
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. That leaves you paying just $9.50 for a battery you can carry around in your pocket, backpack, or purse. 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. It's from KMASHI, and with the coupon code LIKWGR6D, you can bring that price down to $20.
Then once the mail person drops it at your door, you can charge it up, stick it in your drawer, and wait out the next local disaster. 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. $12 for 12000mAh? Not bad at all.
The HooToo Prism comes with two USB ports (5V/1A and 5V/1-2.4A) and an LED flashlight. 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. Project Fi is relatively cheap, but the Nexus 6 is not. The latter is also a pretty girthy device to choose as your one-size-fits-all solution. 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. According to Weibo, the as-yet-unseen phone will sport two batteries inside its bay, both of which are removable in a hot-swap configuration. 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). They're hoping to ramp that up to 750 by the end of next year and 780 by 2017, with the plan to begin shipping new products with these advances by then as well. 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
