KARECEL Over-Heating Protection Electric Hand Warmer

Electric hand warmers have many advantages over the more traditional chemical hand warmers. For instance, not only do they lack the smell of chemical hand warmers, but they’re rechargeable and can be used numerous times. In contrast, chemical devices of this type are typically single-use.

The standard battery life for an electric hand warmer is 5200 mAh (milliamp hours), which provides two to eight hours of heat. If you’re looking for a longer battery life, you may be happier with a warmer that comes with a 6000 or 7800 mAh battery.

When selecting a hand warmer, take into account the ways you plan to use it. Some are best suited to being slipped comfortably into a pocket, while others are designed to match the shape of a hand.

Heat settings also vary, with most hand warmers offering three heat settings that range from about 100F to about 130F. If you plan to use the hand warmer in outdoors settings, higher maximum temperatures may be preferable, whereas the lower heat settings can be ideal for cuddling up at home on chilly days. At a weight of only a few ounces, an electric hand warmer is easy to carry in a pocket or purse when not in use.

A final consideration is the power bank feature that comes on electric hand warmers. While most hand warmers are compatible with a range of Android and iPhone devices, double check the compatibility before purchasing. Here again, a stronger battery will provide faster charging for your devices.

• Never use the heating and the phone-charging functions of a hand warmer at the same time.
• Electric hand warmers are double-sided. Hold them between your two hands for maximum heat and comfort.
• If you’re experiencing joint pain or cramping, electric hand warmers can be held against the area for pain relief.
• The device may be slower to warm when you first take it out of the box, but don’t worry: performance typically improves with multiple uses.
• Electric hand warmers have many safeguards against overheating or overcharging. Even so, check your device’s manual and be sure to follow all safety precautions.
