My go-to example is an inverter I got for my drill batteries. It’s a box that plugs into my 20V drill batteries with a couple USB ports and a 110V wall outlet on top. It can produce 150 watts maximum from that socket. The reviews for this device are split between 4 and 5 star reviews from people who know what that means, and 1 star reviews from people who don’t. “Won’t run my air fryer. Would rate 0 stars if I could.”
