If you’re like us, your gadgets are always running out of juice on the go. You could keep toughing the half-days without power, or pick up a Powerbag. Like the name suggests, the Powerbag’s selling point is a rechargeable and removable battery pack that recharges your other devices. The battery pack can juice up tons of stuff through its array of adapters (micro- and mini-USB, Apple dock connector) or through it’s USB port. Different battery pack sizes are available as well.
