The OCOOPA 118D hand warmer can warm up to about 131°F (55°C), according to the manufacturer's product description. It should keep your hands nice and cozy when it's chilly outside.
Besides keeping you warm, it also works as a power bank. However, some folks have run into issues with USB-C compatibility. Seems like not all USB-C cables fit right, so you might want to stick with the specific USB-C converter or the cable that comes in the package, just to be safe.
A heads-up—charging time might be a bit longer than you'd expect, so it could be inconvenient if you're in a hurry. And while it can charge devices, don't count on it to fully power up your phone or bigger gadgets. It's mainly best as a hand warmer.
If you just need something to keep your hands warm, the OCOOPA 118D does the job well. Just watch out for the cable stuff, and you're good to go!
