Dont run out of power, wherever you are! The PowerGorilla is the ultimate back-up power supply for electrical gadgets.
It stores enough energy to charge most laptops fully, giving you an extra 2-6 hours use (dependent upon specification). 7 adaptors are included, (allowing you to charge most laptops, mobile phones, PSPs and BlackBerrys) together with 12V and USB adaptors which connect SatNavs, PDAs, iPods and other MP3 players. It takes 2-3 hours to charge from the mains, giving approximately one full charge of a laptop and several charges of smaller devices. UK, US, European and Australian plug adaptors are included along with female laptop adaptors so you can use your existing laptop power supply.
