There seems to be a lot of Facebook pages promoting adapters for power tool batteries that can run 12v items , even fridges ?

not sure how long a fridge would run on a 5amp ryobi or ozito battery great for other smaller voltage or low amp power devices

there are so many of these ads, they are charging ridiculous prices, when one can pick similar items on temp or aliexpress so much cheaper..

are these Facebook pages driven/developed by AI Im thinking it is false advertising, or am I wrong ?
