It should be noted that due to the need for heaters to generate a certain amount of heat, special attention should be paid to safety issues during use to avoid fire or other safety accidents. At the same time, due to the fast heating speed of the electric heater, it may cause the heating medium to deteriorate and carbonize. Therefore, careful operation is also necessary when using it to avoid damaging the equipment.

When charging, please use the matching charger and charging cable to avoid using unsuitable charging devices that may cause battery damage or safety risks. When using a heater, please ensure that there are no flammable materials around to avoid a fire. Do not use the heater continuously for a long time to avoid overheating of the battery or damage to the equipment. During charging and use, please keep the ventilation port of the heater unobstructed to avoid blockage and overheating of the equipment.
