Whether you’re spending time outdoors, looking to relax stiff fingers, or just trying to stay toasty in a cold room, an electric hand warmer offers a quick and easy way to heat up your digits. The best rechargeable hand warmers have multiple heat settings, a compact design that’s comfortable to hold and easy to transport, and a USB-rechargeable battery that’ll give you seven to nine hours of warmth at a time. Plus, they can all act as power banks for other USB-chargeable devices.
The majority of electric hand warmers offer three heat settings, ranging from about 95 to 131 degrees Fahrenheit, but if you want more control, I've included a hand warmer here with six heat settings. As far as charging goes, the best hand warmers have a battery life of about seven to eight hours on one charge, but you can also opt for one that’ll last up to nine hours. There are a few extra features to consider, too. For example, if you’re going cold-weather camping, you might want a hand warmer with a built-in flashlight, so you can find your way around in the dark. Another thing: While most hand warmers have lights that indicate the heat level, you can choose one with an easy-to-read display that shows you the exact temperature — perfect for those of us who love details. One thing all these picks have in common? They’re shaped to fit comfortably in your hand, and they're easy to stash in your pocket or bag, so they're ready to warm you up anytime.
For maximum convenience, all these warmers double as power banks you can use to charge your phone and other devices. Ready to keep your hands toasty warm through the winter? Read on for the best rechargeable hand warmers, which are all available on Amazon.

Choose from six colors, including silver and black.
According to a fan: “This Zippo hand warmer is freakin' awesome. It runs on a battery that can be charged just about anywhere; I recharge mine using my computer. It heats up really fast, and cools down just as fast. And, it gets really warm."
