to give you an idea, i cant run my pandora without a battery on the supplied pandora charger, but i can with official psp charger is no battery is inserted in pandora. and the psp charger charges it much quicker imo. of course, since ive seen that theres different chargers supplied with pandora, even within the same region, your mileage may vary. i too have the UK charger+travel adapter. it works...just psp charger works better i think, also the cable is longer
