This is a small / compact USB charger for RYOBI 18V One+ batteries.It uses the Ryobi 30001044 replacement terminal that snaps in. You can purchase different 12-24V Sockets to install. I have used one that has two QC 3.0 USB ports.I had nice short Amazon links here of the parts I used, but Thingiverse edited my summary and changed all the links so they could make money off of them.

$620 for battery box with solar, may not include charge regulator
Apparently a bad choice with Wink, according to the reviews. Guess I'll build my safety system separate from the automation at first.
closet lighting?
This is a great idea, and could be used in a car, etc. Small enough to take with you when you travel.
replaces the Ray-o-Vac rechargeables, should re-charge in my charger without modification
A must when you turn off the PC's power strip. Why can't they use ultracapacitors or something?
