Keep your smartphone charged wherever you are with the Curve 2600 Portable Power Bank. It comes fully charged out of the box, with enough power to fully charge your Apple iOS or Android smartphone. It's great for a weekend away, or whenever you need some extra juice to get you through the rest of the day. Just plug it into your handset using a USB cable to power your phone on-the-go. When the power bank itself needs charging, just plug it into any USB phone charger to have it ready it for your next outing.
