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.
