The power socket in my 1.2 boot. Is it on the same circuit as the one up front? Reason i ask i put an extra one up front for more USB. I use one for the Sat-Nav and other two for keeping phones charged when we go away. Going to mainland Europe in two weeks . My main digital camera and a spare one take an age to charge so i was thinking of putting them in the boot. Sat-Nav up front and phone and possibly wife using the Hudl up front when on charge. I dont want to over load anything so hoping they are on another circuit.
