Hi have a second hand Nokia 770 which came with most accessories. Based in UK but charger is an AC 4U two pin plug which i have not seen before in UK. Voltage says 100-240. It looks like US style plug but not sure whether can use simple plug adapter for this? This is probably quite simple but dont want to ruin the thing. Product box says Made in Estonia. Ive looked on youtube sites and niether they or instructions show charge being connected to socket or with plug adaptor. What do i need to charge this to UK plug connection firstly? Thanks for your help im feeling like Homer Simpson.
