PSP Charger

I found this today in a box of junk at a thrift store I seen PSP and grabbed it and I noticed the plug is different, I know I've seen this before years ago and if I am not mistaken this was for Japan. Will I be able to use this on my psps (with the adapter of course, that I don't currently have) or can I go all mad scientist and splice a plug onto this. ...or am I SOL and out a buck I paid for it?
Whoa, for those on the vintage site sorry for the huge pic...

However we use 240v here and irrc the us is like 120v so again shouldnt make a difference as youre going down in voltage but I really have no experience with US wiring/home electrics.
Prob better if you consult someone with us domestic electric experience though...
