I've just got a camera with a charger that uses a 2-pin power lead (figure of 8). However it's american plug.

so i went and got an english one and was about to plug it in but i looked at the lead and it said 2.5a250v whereas the american one says 7a125v. The battery charger's input says 100v-240v & 4.5-8.5va....

i need an adapter don't i?
