First of all, I know I should have posted this a few months ago before it was April and 60 degrees F outside, anyway…
Yes, USB Hand Warmers are a thing! I was joking that it’s just a USB power bank that shorts itself out and overheats, but hand warmers you can charge via USB are totally a thing… And I tried a pair out.
I actually ended up giving these to my daughter who was hoping for “electric gloves” (sorry!) and she said they’ll work just fine… but I did test them out a bit before she got them. These “OCOOPA Magnetic Hand Warmers Rechargeable” were just under $20 USD and they did work well. The magnetic part just means they stick together on the flat side. I’m not sure it’s an amazing feature unless you think magnets are magic. (Some people do!)
I think my only complaint is that the little LEDs to show if it’s charging or the battery is low are difficult to see. You need to get the angle just right to see them as there are tiny holes that lead to the LEDs mounted inside.
The warmers were small and slim enough to slide into my pockets for a winter bike ride and then put into my gloves (facing my palms) once I got off the bike. So yeah, just like magnets these totally work. USB Hand Wamers. Cool. (I mean, Warm!)
