What we love

This ultra-thin LISEN power bank is just as slim as the latest iPhone Air at 0.2 inches. It’s a credit card-sized model that’s even made to look like one, and it packs a 5,000mAh battery inside its metal shell. There’s even a built-in braided USB-C cable that lets you travel without carrying an extra one.
