Power banks aren’t usually exciting, but Anker’s 737 is different. It’s the kind of portable charger that makes you wonder how you managed without it. This isn’t your typical battery pack that barely charges your phone once; it’s a powerhouse that can handle everything from phones to laptops with serious speed.

This amazing Anker power bank is perfectly capable of charging your phone or laptop on the go. Even better, it’s 40% off, so you can get one for $90 from Amazon.
