How does it work?

1/ At home, recharge your Voltmaker just like you'd do it for your telephone, using a wall socket or your computer. This will recharge the Voltmaker's internal battery.


2/ Is your phone's battery dead? Plug the Voltmaker into your phone. You can fully charge it with the energy contained in your Voltmaker's battery.





3/ Are your phone AND your Voltmaker's batteries dead? With a few whirls of the wrist this hand-held device is capable of generating a few extra minutes of power for your telephone or other small, low power devices (MP3 players, torches, GPS devices, cameras, etc.)

Which devices are compatible with the Voltmaker?

Any device that can be recharged via USB is compatible with the Voltmaker. If you have any doubt, do not hesitate to contact us!
