🎰Rechargeable

This rechargeable mini-heater is designed to keep your hands warm on cold days while you walk down the street, after skiing, if you're camping... and is especially 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, thus transmitting heat from the power bank to the hands.

Furthermore, as it's a portable power bank, it allows you to charge all your daily devices like phones, smartwatches, and connected bracelets via a USB charging port.

🎰Is it safe?

Before you start heating your hands with the power bank, you might think it could explode in your hands... but there are no worries on that front.

It should be noted that you cannot use the heating function simultaneously while charging your phone.

🎰Protection System

Like any power bank model, these devices integrate a protection system against overvoltages, overcharges, short circuits into their circuitry, and also have a temperature sensor that will automatically shut down the device if the temperature exceeds 55°C to prevent overheating.
