Anyone any experience or knowledge of these?
I have a tom tom sat nav, and the battery life is piss poor. Generally it's not an issue because it's plugged in, but I just made a long journey in a hire vehicle and the plug in socket didn't work. I had to save the tom tom for emergency use only, which was a pain in the arse.
I'm thinking of getting a back up power pack, but the choice and reviews seem varied to say the least.
