Hand warmer with three power settings. Extra comfortable long-pile inner fleece helps warm your hands immediately when you put them inside. You can then start and regulate active heating in three steps after connecting the warmer to a power bank using the built-in cable with a USB-C connector. Any compact power bank that can be inserted into the pocket on the heater is sufficient for power supply.
After connecting the USB cable to the power source, the switch will flash briefly. Activate the heating by pressing and holding the switch. You can then choose from three power levels by briefly pressing the switch, indicated by the colour of the switch backlight. Press and hold the switch again to turn off the heater.
