Review on Powerful 40W USB C Car Charger - Dual Port All Metal Fast Car Charger for iPhone 13/12 Pro Max Mini, 20W Type C PD Car Charger for iPhone 11 Pro/Max/SE/XS/XR/8, Galaxy S20/S10, iPad Pro, AirPods Pro by Bobby Plymell

I never get enough USB-C so I bought it to use with a small generator. It works well. I can charge all kinds of devices. Glad to get one today as I tried to charge a small battery with a regular USB-C charger on my little generator. When I tried to charge it from a small USB-C generator, the generator took charge since the USB-PD works in both directions. When this product is plugged into the same DC plug of a generator, USB-C will charge the battery instead of the generator. I love it so much I'm buying another one for my car.
