“Striking the perfect balance between price, portability and capacity". ——Marie Brewis, editor of PCAdvisor.co.uk. 

The pocket-friendly A2 is our smallest portable charger, but with super-high-density battery cells, it'll keep your phone charged long after the day is done.

ZEN+: Ultimate compatibility

The A2 automatically detects your device and fine-tunes the output to charge it at maximum speed (up to 2.1A). Enjoy top charging speed with a "Zen" peace of mind

Compact & Lightweight

A2 is one of the most compact and lightweight external batteries in the market for its capacity, thanks to the use of top quality components. With 6,700 mAh capacity, you can easily triple the time between plugging your phone into the wall.
