I have a Uniross Sprint 90 AA battery charger. I use it quite a lot overseas, using a conventional foreign->UK adapter but those things are always a PITA, especially as they are bulky, the pins never grip very well, and the weight of a loaded charger is often enough for them to just fall out.
However the mains plug-in bit on this charger is readily removable, obviously to enable Uniross to sell the same product in many markets - you often see the same thing with wallwarts for mobile phones etc these days - mine came with a full complement of adapters which I can swap over in other countries. Unfortunately however the Sprint charger doesn't provide them.
See:
Anyone got any bright ideas as to where I could get hold of a US and European version of the plug-in bit? I tried emailing Uniross - to their credit they actually replied, but were totally unhelpful.
There has to be a better way than buying a whole new unit in the US and just dumping the charger part!
