Tested to perfection
ZenPower Duo is small, powerful and beautiful — and built to last! We put it through 5,000 USB-plug insertions and removals, subjected it to repeated extreme-temperature tests of between -40° and 70°C, and drop-tested it from pocket height of around 80cm, time and time again. ZenPower Duo has been tested to perfection to survive everyday life!
