![]() The Anker PowerCore 13000 features four battery-indicating LEDs on its side alongside a button to turn them on. The only significant downside we could find was the charging speed: It takes a little more than 51 minutes to charge an iPhone 11 to 50%. While its capacity isn’t huge, it’s more than enough to bring an iPhone 11 or Samsung Galaxy S10 battery back to full life. That’s 73% of the expected value, which is 12% better than average in our testing. While its maximum capacity is stated to be 5,000mAh, we measured it at about 3,655mAh. The charging capacity of the Power Pocket 5k is modest, but it did come closest to living up to its claimed output out of all the models we tested. This portable charger is really the definition of a personal power bank, easily whipped out of a pocket and held alongside your mobile device. It was the smallest and the lightest charger we tested you might even mistake it for the phone in your pocket. There are few places this battery won’t fit, yet many devices it’ll charge. When we first encountered the Belkin Power Pocket 5K, it was hard to believe its size: just 5 inches long, 2.5 inches wide and a half-inch thick. The most portable: Belkin Power Pocket 5K Overall, not only does the Anker PowerCore 13000 pack major mAhs, but it’s got two ports for your USB cables and is fairly small and durable. ![]() (You can read more about our durability testing below.) And it’s durable: The charger survived our drop tests, which included a 3-foot drop onto grass and a 1.5-foot drop onto carpet, with neither external nor internal damage. It’s about the size of a full wallet, so it’s easy to carry around. The charger’s matte plastic design feels nice to the touch and resists smudging surprisingly well. Four LED lights alert you to the charger’s remaining battery life, with a button on the edge to turn the lights on. ![]() When we charged an iPhone 11 and a Nintendo Switch simultaneously, the battery barely heated up. The side of the battery houses three ports: dual USB Type-A ports (which are fast-charging) and a micro-USB port to charge the battery itself - allowing you to run several USB-C cables to different devices all at once. (You can read more about how we measured mAhs by scrolling down.) Plus, it’s just a few more bucks than the Belkin Pocket Power 5K for more than double the mAhs. In other words: None of the portable chargers we tested fully lived up to their claims, and the PowerCore 13000 still has more charging capacity than most others we tested. While the PowerCore 13000 doesn’t fully live up to its promise of 13,000mAh (we found it delivers 7918mAh), it hit a respectable 61% of what’s advertised - a percentage that put it about average among all the batteries we tested. And you won’t be sitting by idly for too long, either, as the PowerCore 13000 takes just 41 minutes to charge an iPhone 11 to 50%, tied for fastest charging in our testing. The PowerCore 13000 has enough capacity to bring an iPhone 11 to full charge two and a half times, or two Samsung Galaxy S20s from empty to more than 90%. You can charge a lot with this thing - and quickly. Simply put, the Anker PowerCore 13000 packs a ton of value. “Chakratec is accepting orders and preparing for deliveries of its power booster with fast EV chargers in 2018,” said Nir Zohar, Chakratec co-founder and VP of Business Development.Your CNN account Log in to your CNN account This collaboration allows chargers to be installed in remote locations where upgrading the grid makes no sense.” ![]() “These new electric versions will only sell if we are able to charge them safely anywhere, without stressing the grid. “Car manufacturers are announcing new EVs, and behind the curtain we are making it possible,” said Alexandre Borgoltz, Sales Director of DBT-CEV. The power booster is modular, starting at 100 kWp and scalable to multiple MWp. The companies say their jointly developed system can triple the power available from the grid. It’s also more environmentally friendly, as it uses no chemicals.Ĭhakratec has partnered with French charging solution provider DBT-CEV to combine its energy storage system with DBT’s fast charging stations. Chakratec says its “kinetic battery” can provide a virtually limitless number of deep charge cycles over its expected lifetime of 20 years. The Israeli firm Chakratec, established in 2013, manufactures a kinetic energy storage solution based on a flywheel. But chemical batteries may not be the only solution. The advantages of adding stationary energy storage to fast charging stations are well known. Posted Octoby Charles Morris & filed under Fleets and Infrastructure, Newswire, The Infrastructure.
