I've run US power tools from a 110V box, having checked first it was capable (I had a one that had a tiny capacity). Grinders, saws etc - just run slightly slower. I've had a Dewalt grinder (with a very easy to use underslung switch) for 15 yrs or so. Just before Aldi popped up with their portable bandsaw last year, I dragged a Harbor Freight one back over, swopped plugs and it works rather well.
I've got a Bauer battery angle grinder as well - charger running fine.
