Many people have ever used hand warmers. Traditional hand warmers are made with chemicals. One popular kind is disposable hand warmers. When you squeeze the packet, the chemicals mix, and a chemical reaction occurs that generates heat. You can not adjust the temperature. It depends on the intensity of the chemical reaction. When the reaction ends, the hand warmer will no longer be warm, and you have to throw it away. Needless to say, this is wasteful. And if you’re using hand warmers every day, they can get costly over the long run. The cost of about 60 disposable hand warmers can get you an Ocoopa rechargeable hand warmer, which can be reused hundreds or even thousands of times, and enables you to adjust the temperature. It not only helps you to save money but also reduces waste generation.
