@reverseics@infosec.exchange @nstarke@bird.makeup In China, these things are basically everywhere online if you look for them, known by many different names, such as "power savers", "electronic mouse repellents", "lead-acid battery maintenance device", etc. All of them have the same design, and sometimes same PCB - an AC passthourgh outlet, and an LED. Almost nobody who knows what a watt is believes them, unfortunate, grandparents sometimes fall victim to them so they still get sales.
