I’ve combed through plenty of portable power banks during the holidays, and Anker’s has enough juice to keep my gear running for hours without needing to find a plug-in. It offers 24,000mAh power, and it can fully charge an iPhone up to 13 times, or an iPad Pro 1.3 times. While it may be a larger power bank, the design features an LED interface where I can see exactly how much charge time I have left on the bank. I also can see the wattage output for up to three devices. It can go up to 140 watts, promising a speedy charge when you need it most.

With over 800 reviews, its average rating is 4.6-stars. ZDNET expert Adrian Kingsley-Hughes raved about the device in his hands-on review, saying, “the 140W output is a massive game-changer for keeping my MacBook Pro charged up when I’m out and about. The bright, crisp display adds value rather than being a gimmick, and the addition of a USB-A port along with the USB-C ports means that legacy devices don’t get left out in the cold.” Read the review: Anker 737 power bank review
