Complete with two usb ports, one super fast USB outlet recharging at 2.1A, the other a standard 1A output all powered by the 20,000mAh Lithium battery.

This range of GP Powerbanks have built in short circuit protection and loopback protection which is an auto cut-off if a cable was plugged into the input and output at the same time. Over temperature cut-off during Powerbank recharging. Under-temperature protection to prolong battery life. Overcharging  and discharging protection together with overload protection. This GP Powerbank mobile charger also complies with UN38.3 air safety standard.

Ideal for people on the move, commuters, campers, hikers and festival goers. These safe GP Powerbanks have been advertised on TV. The TV ad campaign highlights the need for power to show a boarding pass download to a mobile phone or also during a vehicle breakdown trying to call the breakdown services.

The GP Portable Power Bank comes with a charging lead, and this particular model can charge the iPad and Galaxy Tab directly. Use the USB lead that came with your mobile device to suck the energy out of the Powerbank. The clever 4 LED battery level indicator makes it easy to see how much power you have left.
