Just plain too bulky and expensive. The Milwaukee fan draws 1.25 amps on high. Most other 18V tools peak at up to 30-40 amps.

This is easy. The battery to tool connection design is usually covered by a design patent. Nobody can manufacture and sell an adapter if the tool company says no. Tool companies want to sell batteries.

I don't see how those little motors stand that.
What's the 18v drop down to with that kind of current draw?

It is kind of impressive when you think about it. Then again, starter motors are drawing hundreds of amps.

Surprisingly voltage drop is not much. If you maintain that draw until the battery is dead, it gradually decreases from about 18v down to 15v.

The second line up is the 20a rate, but the XC batteries have 2 sets of cells and can output 40a+.

Sincerely, the battery nerd.

Hitachi used to make a kit that came with a plug in adapter.

Re: Why Doesnt Anyone Make A Battery Converter?


the whole point is not doubling up on tools. I guess for you that pull 20foot trailers this isnt an issue, but its still running back to the truck.

Re: Why Doesnt Anyone Make A Battery Converter?


@Golden view, there is a forum that talks about batteries quite a bit, and I've learned some things from them.
Strangely, some of them seem to equate photons from flashlights with bullets from guns.
