I have some fairly large DeWalt 18V batteries, which run, e.g. my Cordless LawnMower.
I imagine that they'd also run my Corded tools, at least for a while, if I could connect them up.
But I can't find any such DeWalt product :( And I don't know what term to search. All I find when I do searches is products designed to allow the opposite - running a battery tool from the mains.
Do these products exist? and if so what keywords should I be searching for?
