Or see any downsides?
We all have heard about home fires started from power tool battery charging fires.
How about gutting/disabling an old micro wave, SS would be ideal, slap a working smoke detector on top, drill a hole for a power cable in a good spot, locate in garage/non living space(?) and place your battery charger inside, plug into a GFI, and use it to charge your power tool batteries?
I have all my workshop outlets on a switch by the door. When I leave I turn off the lights and the outlets.
No problems anymore.
I initially did this so my kids couldn't accidentally turn something on that might hurt them. They are all grown up and moved out now and I still use it.
