HARGING
The temperature gauge uses Li-ion battery as the power source. It usually takes 8 hours to have the
battery fully charged. The temperature gauge can be continuously used around 50 hours with a full
charge.
It’s recommended to use the specified charger or USB cable to charge the temperature gauge. The
charging voltage range should be 4.7V~5.2V and the charging current should be equal or greater than
500mA.
Charging via the USB cable
Unwind the USB cable, plug one end to the USB port on the bottom of the temperature gauge and the
other end to a PC or other standard USB port.
Charging via the specified charger
The temperature gauge can also be charged by the specified charger which includes 4 worldwide
adaptors: Australia/China, Europe, UK, and US/Japan. A micro USB to USB type-C converter is
provided since the cable end of the charger is not standard USB interface.
To charge the temperature gauge, plug one end with the required adaptor to the power supply and
the other end with the converter connected to the USB port of the temperature gauge.
