The PowerGorilla is one tough monkey! Yep, that pun IS intended, but none-the-less accurate! From the moment we opened the box it was easy for the Uber Staff to tell that this was no run-of-the-mill charging device. It’s solid and compact. The LCD screen lets you select which voltage you require and also indicates which setting has been chosen, as well as how much “juice” is left in the PowerGorilla. The unit comes fully charged, so we plugged in our iPhone – which was dead – and ZAP we were charging .By combining the PowerGorilla with their SolarGorilla Solar Charger, you can get a complete “solar system” designed for maximum portability and ultimate charging capabilities! The one-touch button technology makes the PowerGorilla easy to use and its sleek, aluminium casing with shock resistant rubber protection strips makes it totally robust.
