Your best bet is to Google the area you're going to visit. I'd recommend an outdoors store. It will come with the 110vac charger and a car charger adapter. I bought a 220vac charger from
www.burton-mccall.co.uk (UK maglite franchise). I think it was about 20 quid, or you could buy a transformer from Maplin with the right output and crimp it in! I'd recommend you buy some spare bulbs in the US. They're about half the price. I find they last very well as long as the torch isn't dropped!! Hope this helps.
