Winter is here, and due to climate change, it has become more harsh and unpredictable than ever. In addition to the usual mittens and gloves, many people choose hand warmers to protect their fingers, but unfortunately, hand warmers are not always reusable-the last thing we need is to accumulate more under the snow. Lots of waste. This begs the question, are there any reusable hand warmers or the like? Read on for non-one-off options.

There are several types of hand warmers, and they all work in several different ways. You may be most familiar with the air-activated hand warmer. These insulations contain cellulose, iron, activated carbon, vermiculite and salt. According to ScienceIQ, these components generate heat through an exothermic reaction. Unfortunately, the reaction stopped within an hour or two. 

Other hand warmers use battery power, charcoal or other chemical mixtures to produce a temporary warming reaction. Air-activated hand warmers are mostly disposable, but fortunately, there are many reusable hand warmers on the market that are equally effective and have a longer lifespan. Take a look at them, as follows:

HotSnapZ hand warmers are similar to air-activated hand warmers in that they are small bags that retain heat through chemical heat. Each pack lasts about half an hour to an hour and can reach up to 130 degrees Fahrenheit. They also happen to be rechargeable and reusable. Just put them in boiling water for about 15 minutes and you can start using them. These bags come in two different sizes, four in each bag. 

The Snappy hot pack can heat up in three seconds without the need for electricity. Like HotSnapZ, the internal temperature of the Snappy backpack can reach approximately 130 degrees Fahrenheit. Unfortunately, they only last about 20 minutes to cool down. Nevertheless, they are reusable and can be charged in boiling water in about 15 minutes. They are non-toxic, have passed FDA certification, and are made of food-grade materials.

The Zippo hand warmer is a pocket-sized hand warmer that can be refilled and refueled with Zippo's own brand lighter liquid. They have different colors and different durations, indicating that the fuel inside can last for 3, 6, 9 or 12 hours. Zippo claims that the lighter liquid used in the heater burns clean and environmentally friendly, but it is not sold with the heater itself.

Ocoopa's rechargeable hand warmers are made of aluminum and come in four different colors. Unlike some other heaters, this heater relies on battery power and has a double-sided heating function. This heater has several different heating settings, ranging from 95 to 131 degrees Fahrenheit. Its 52,000 mAh lithium battery takes about three hours to charge, but it stays hot for a much longer time than some other heaters, between four and eight hours. 

Fourheart's hand warmer provides double-sided heating. It will heat up in 15 seconds and last about 6 hours before it needs to be recharged. This hand warmer is powered by a rechargeable 55200mAh lithium-ion battery and can be charged via the USB Type-C charging port. The Fourheart heater also offers three different heating settings: 107, 118 and 131 degrees Fahrenheit.
