The Best Rechargeable Hand Warmers
When temperatures drop, our extremities are often the first to feel it. Whether you're keeping busy in the freezing outdoors or just looking to stave off an unpleasant chill, a rechargeable hand warmer could offer the help you need. And with a handy high-capacity battery onboard, these useful gadgets could also provide a little extra juice for your phone or other portable devices while you're out and about.
What to Look For
Each of the devices we reviewed has its quirks and benefits. If you’re mindful of the battery capacity, connectivity options, and maximum temperature during your search, you’re sure to find a model that suits your needs. With that in mind, we fancied a few rechargeable hand warmers of our own. For example, our favorite on the market was the solo hand warmer from Ocoopa. Though it’s a little pricier than competing two-packs, this smart design comes with reliable features and a large surface area that won’t have trouble keeping both hands warm at once. But if you’re looking for a hand warmer that makes the most of its portable charging ability, check out Bodbod’s high-capacity 12,000mAh option, which features an integrated charging cord. Read on below to get the rest of our hands-on advice.

Frequently Asked Questions
Are rechargeable hand warmers safe to use on bare skin?
Though the temperature range varies between devices, many hand companies claim their hand warmers can reach impressive highs of up to 130 degrees Fahrenheit. Human skin can be sensitive to burns from prolonged exposure to temperatures as low as 115 degrees Fahrenheit, so we recommend taking extra precautions and protecting your skin with gloves when using the highest temperature settings. Even low temperatures can cause burns over time, so avoid using these devices unattended such as when you sleep.
Can I warm my hands and charge an external device at the same time?
Many of the rechargeable hand warmers we reviewed are also equipped with output ports, so you can put the internal battery to use to charge other devices. In most cases, the heating function is disabled when you use these ports, meaning you can’t heat and charge at the same time. This can vary based on the product in question, so check the user manual if you want to be sure.
