Very convenient, excellent compatibility

This auxiliary battery can charge any device designed to be loaded on a USB port.
Some adapters are included for some models of mobile phones, and a standard USB adapter allows you to connect the cable supplied with the device to reload.

Be careful though: do not expect to charge your device directly from the solar panel, this one does not provide sufficient power, however it can slow the discharge of the battery while it is powering your device.

- Samsung Galaxy S (original cable + USB adapter provides)
- Supply of fan support ventilated laptop

The full recharge of the booster battery via the solar collector is announced between 10am and 15h (depending on sun exposure).
