This battery pack uses AA batteries to power and charge your gadgets. It can be plugged into the power socket of your device just like a normal power adaptor. 4x mid price disposable AA batteries can fully charge a 4" smartphone, you will get less/more of a charge with smaller/bigger devices. Top quality 'lithium' disposables or high capacity rechargeable will give even better performance.

Charge 1000s of Gadgets - Since the pack features a USB socket it can charge the thousands of devices which charge from a computer's USB socket including most phones, Satnavs, android smartphones from Samsung, HTC, etc. iPhones are not compatible, tablets are not compatible since AA/AAA batteries don't have enough power for them. AAA batteries have low capacity and aren't designed to cope with the amount of power most devices need so we don't recommend using them to charge your devices.

AA/AAA USB Battery Charging - The pack can charge 2 or 4 AA or AAA rechargeable batteries from a USB socket, simply press the button on the pack to switch between input and output modes. An LED will change colour to let you know when charging has finished, the pack will switch off automatically when the batteries are fully charged, and will auto detect non-rechargeable batteries.
