Get a 110 charger, :Cwith the quality of battery tools always on the up, I don't really understand 110v tools.
Especially as you have to drag a massive lump of pig iron about too!
the only draw back I can see is the lack of 230V outlets on a site to charge your batteries.
:C
I got a yank charger for my stuff and stuck a 110 plug on it,
I have a 110-230 converter somewhere, but fkd if i can find it, modded it from an old site light florrie, but they are nearly all 110 designed now,
