Mm...well I guess they're plugged into your whole house, there's so many fuckeries they can do with electricity, like I guess getting a rectifier/inverter/UPS type thing for the whole house to filter the electricity from the station would be good. Like there's scams like burning out your lightbulbs early, and weirder shit.
There's an invention, new device. Shitty power station filter. And tells you to keep the receipt so you can prove you were motivated to buy one, and keeps a log of how shitty the supply is, and how much it's saving you on electricity.
