power banks
Mobile device lifelines
Power banks are portable batteries that store electrical charge for recharging phones, tablets, and other devices on the go.
They're essential travel gear when outlets aren't available: My phone died but I had a power bank in my bag.
Capacity is measured in milliamp-hours (mAh)—higher numbers mean more charges before the bank itself needs recharging.
