48 ratings, 46 reviews, 100% five-star, is not suspicious - at all.

So what is this? Some sort of electronic way to keep yourself warm? Why is this the first time I'm hearing about this on this site? Does nobody else sell a similar product, perhaps under a name with 8 consonants, at least 3 of which are z's, and 1 "y"?

With the power of AI, it KNOWS when you've pushed the power button so it can use its machine learning prowess to tell the internals it's time to get to work! Before AI, we had really tiny organic beings turning cranks to power electronics when we pushed the on button.You're saving lives by going AI!

...maybe look at other hand warmers in slickdeals search ... some are heating on 2 sides, and some are heating on only one side. Some have bigger batteries, ect.
I bought a different hand warmer the other day, and it heats both sides, ... I'm just offering the suggestion to see what hand warmers seem to be good and ones to avoid, from users that actually have experence with them. I'm in florida, so it is just starting to turn colder, ... 57 degrees outside right now. That is COLD for florida, but we have people who have it much colder. I am mostly planning to use it in home, with blanket over me with jacket on the coldest of days, and turn off all home heating. I'll get back to you then.

I'd get these instead. They are dual sided, has flashlight, digital readout, 8 modes, wrist straps, double usb-c wires in a single cord. Code still worked as of today 10/31/2025.

I bought few days ago, at lowest heat setting lasts less than 7 hrs. vs Described 20hrs, just returned to amazon, definitely not 4000mah.
