I remember when 10 to 12 hours of battery charge time was considered a lot -- and that was only two or three years ago. Now we’re seeing mind-boggling charge times, even for small devices. The EcoPebble Powerbank can easily be held in the hand, yet boasts a 50-hour charge time -- a helpful thing, because it’s designed to charge your other devices. It’s also a Bluetooth speaker and a 200-lumen LED flashlight.
