A power bank is a portable device designed to recharge your electronic gadgets — mainly smartphones, tablets, wireless earbuds, smartwatches, and even laptops — without the need for a wall outlet.
Also known as portable chargers or external batteries, power banks store electrical energy in internal batteries, which can then be used to charge other devices on the go.
