Here’s some of what the company says about it: Comlife 2-in-1 Hand Warmer & 20000mah Power Bank features an easy-to-grip shape and size with plenty of battery power to keep your hands warm and toasty for hours. There’s no better companion on a cold day or whenever you’re feeling chilly! Not only can it be your hand warmer, but it can also be your power bank when your cell phone is power low. Rapidly warm up single side or double sides in seconds, press the switch and instantly release the warmth for you. (Giz Wiz: Well, really not in seconds, but maybe a couple of minutes.) Built-in 20000mAh polymer lithium battery and Type-C charging port, only 7-8 hours charging time can make sure 5-10 hours working time. (It charges faster via USB-C which is what I use.) Made of high quality Aluminum alloy and flame retardant PC material. Small enough to put it anywhere you want, hold it in your hand or put it in your pocket. (Giz Wiz: Not too small. Approx 6 1/2″ X 3″ X 1″ & on my scale it weighed 1lb 1.1 ounces.) I paid roughly $38, but it had dropped by $5 on 10/30/20. That price can change at any time!
