This Power Bank Is So Good, I Bought TwoThe Anker 737 is my personal go-to power bank, and it's on sale for Amazon Prime Day.The Anker 737 used to be WIRED’s top pick among all power banks, which is why I first purchased it. I needed something reliable to use while camping for a few days; it couldn’t be too bulky and had to be able to charge multiple gadgets simultaneously. The Anker 737 fit the bill. Even outside of camping, it’s proven to be a magical piece of gear that fits seamlessly into my daily life, fueling my Instagram-scroll sessions and then some, given that it can charge three devices at once. Right now, during Amazon’s Prime Day event, it's on sale for close to the best price I’ve tracked. (It has fallen a bit farther in price before, but not since Black Friday.)Photograph: Simon HillAnker737 Power BankThis brick has a whopping 24,000-mAh capacity and can send or receive up to 140 watts. That means it can charge your laptop or iPad as well as your phone or other tech accessories. My favorite feature is that the power bank itself can be recharged in under an hour. That makes it perfect for travel, since I can top off its charge during a few spare minutes at an airport or a coffee shop. The display shows remaining battery percentage, temperature, output, and more.The only real flaw is that the brick is dense, coming in at about a pound and a half. But to me, the upsides are numerous, so much so that I purchased a second one when I misplaced my first. I always have it next to me or in my backpack. At this price, I might get a third one, just in case.Power up with unlimited access to WIRED. Get best-in-class reporting and exclusive subscriber content that's too important to ignore.
