They’re trying to unfuckup the way they strung their Christmas lights, usually. The proper use case is to patch in a generator, and even then, you need a cutover mains disonnect switch, and best left to a professional electrician to fo the work and train you in how to use the backup power system.
@blaineg@mike808@werehatrack A double-male patch cord for a generator connection is commonly referred to as a “Deadman”. The proper cord has a male end to plug into the generator with a female connector to connect to the house wiring (with an interlock/transfer switch). At the house end, there is a special male socket with the prongs recessed in the fixture.
(Yes, there are A-A data transfer cables, but they’ve got a lump in the middle with a tiny little brain in there.)
Who needs brains, right? Just hook that shit up like the boss says. Performs as directed by management. Meets the minimum required, boss. No effort was wasted on that safety bullshit. Fuck regulations. 'Murica!
(Back when Amazon allowed for comments on reviews, every once in a while I’d tell the 1-star review folks they don’t understand electricity. No shit a 12v 2amp AC adapter won’t power an air compressor!)
What a funny write-up on Amazon.
First it says Amazon’s Choice for “usb heated blanket,” and further down, says "Fit for Driving recorder,electronic dog,car charger and other automotive electronic equipment."
