Ryobi makes several AC Inverters and USB chargers. The 40V battery RYi300BG is nice because it has a 300W Pure Sine wave inverter, a USB Type C port 5/9/12/20 VDC rated at 2A, and a USB type A port rated at 3A. Unfortunately it doesn't have a regulated 13.8VDC Cigarette Lighter Socket. This adapter adds that functionality.

It can be used with my 18V battery adapter ( prusaprinters.org/prints/42031-ryobi-18v-to-40v-battery-adapter ) or with SorrowBJD's Battery Adapter for Ryobi 40V battery( thingiverse.com/thing:3561617 )
