Fourteen Cubic Inches Of Win

Some people need more capacity than our smaller batteries deliver. The A5 features five lithium-ion cells with incredibly high energy density. It's one of our best sellers among users who have more than one power-hungry device.

Packed With Features

The unique charge-through function allows you to charge the external battery while it is charging your devices, a feature rarely seen in external batteries. The A-Series battery will automatically turn itself on when connected to a compatible device for charging, then switch back to standby when charging is complete. The A-Series battery can maintain up to 95% of its charge after six months without use.

For Optimal Use

The Zendure A-series is compatible with almost all Apple and Android smartphones, tablets and other USB-charged devices. Use your device's original cable or our included cable to charge your devices. Disconnect all cables from the Zendure battery if you don't intend to use it for a long period of time.
