Though it looks like a familiar fragment of the past, the Power Extension PX-01 is contemporary tech! This power bank’s design takes on a form reminiscent of the classic extension cord reel many of us grew up with. The PX-01, however, features USB and traditional power outlets so you can charge just about anything from just about anywhere. At home or on the go, it utilizes state-of-the-art lithium battery technology to keep everything from smartphones to power tools charged.
