TJ Maxx and Marshall's are fine for picking up Nautica and Ralph Lauren shirt overruns, but I think I'd skip buying anything there that you plug in.

How hot can it get?  USB isn't exactly cranking out a lot of power.  Even USB 3 is only 4.5 watts.  You have to use a special charger to get more power.

FTA: A use and care label with the name "Aroma Home" is sewn into the bottom pocket of the heating pad where the USB cord emerges, CSPC says.

So, does it run on USB, or does it have a USB outlet?

Should keep the crotch fruit warm.

It seems that everyday my local news leads off with a big house or apartment building fire. We need heat from the sun.

You're thinking of what a computer's USB port can put out. Think phone and tablet chargers. USB 2.1 versions of those can put out 10 watts or more. USB-C can do as much as 100 watts. These pads likely draw about 5 watts normally, which is 1A at the 5v that USB ports supply. 5 watts is enough to make a small heating pad like that warm. I'll bet the problem has to do with something shorting out internally. Heating pads like this tend to be made of resistance wire in a serpentine pattern, and there's probably a return wire running down 1 side of it. If the insulation rubs through on the return wire, say, halfway down, and makes contact with the heating wire, you now have a heating pad with half the area that draws twice as much power. And that will get really hot really quick. And if it's plugged into one of those cheap multi-outlet phone chargers that can provide 4 amps or more, and don't have limits on individual outlets, things can get really hot really fast.

Reading is fundamental.  Unless it's packed with a high output adapter, it's designed to be plugged into a standard USB port.

Even assuming that's true, it doesn't come close to solving the problem.

Here's the standard USB charger that may or may not come with the electric blanket.
Here's the fast charger that the user already has next to their bed so they can charge their iPad.
Which one gets used with the blanket on any given night?
