What is a rechargeable hand warmer?
The particular hand warmer is crafted from aircraft-grade aluminum so it remains smooth and comfortable in your hands. It’s also anti-skid, so it’ll stay put in your hands and not slip out of them. It heats in mere seconds, with three levels of heat ranging from 95 degrees all the way to 131 degrees Fahrenheit.
You can keep your preferred heat level constant until the device runs out of battery. No more short-lived disposable hand warmers or cold weather canceling the heat out. When the large 5200 mAh battery is drained, just connect it to a USB-C charger and juice it back up. It even doubles as a battery bank should you need to charge your phone or other electronics — an important feature when you consider prepping your car for winter emergencies.
