Where can i buy?

[Rou]

I need to find a voltage converter to change the english voltage into japanese

Looks like this

Needs to change the voltage not just be a 2prong adapter.
I need it for my airsoft gun to charge it as the charger is for 110V not 240V.

cheers and rep to anyone who can help

Places like currys and halfords often sell things like that
