Do you often have cold hands? With the arrival of winter, our hands are one of the parts of the body that suffer the most because they are continuously exposed to the winter cold.
Rechargeable
This mini rechargeable heater is designed to keep your hands warm during cold days while you walk down the street, after skiing, if you go camping... and is particularly useful for people suffering from hand problems due to low temperatures (Raynaud's phenomenon).
What is a USB hand warmer?
As its name suggests, a USB hand warmer is primarily an external battery that integrates a pair of electric plates heated to a high temperature, generally between 45-55°C, and thus transmits heat from the external battery to the hands.
In addition, as it is a portable external battery, it can charge all your daily devices such as phones, smartwatches and connected bracelets via a USB charging port.
Is it safe?
Before you start warming your hands with the external battery, you might think it could explode in your hands... but don't worry about that.
It should be noted that you cannot use the heating function simultaneously while charging your phone.
Protection System
As with any external battery model, these devices incorporate a protection system against overvoltages, overloads, short circuits, and also have a temperature sensor that will automatically turn off the device if the temperature exceeds 55°C to prevent overheating.
