1800mAh Rechargeable Electric Heating Insoles with Remote Control - Winter Warm Heated Insoles for Boots & Shoes - US Size L (Black) - Perfect for Skiing, Hiking & Cold Weather Outdoor Activities

It has the characteristics of beautiful appearance, heat preservation, breathability, and comfortable wearing. Different keys on the remote control different working modes. The heating material is made of composite carbon fiber or PET nickel-chromium alloy, which has the characteristics of high heating efficiency and strong strength. When the carbon fiber material is energized and heats up, it can radiate infrared rays to promote blood circulation and other health benefits. The insole battery uses a high-capacity polymer battery cell with extremely high safety to ensure the longest use time while keeping warm. Due to the use of high-strength, high-softness composite carbon fiber as the heating element, the problem of repeated bending and damage to the heating element when the traditional heating insole is worn and walked can be avoided. It has the functions of keeping warm, such as convenient use, high heat generation, and strong heat preservation performance.Specifications:Heating parameters:After starting up, the high-end can reach 50-55℃, and the use time is about 2.5-3 hours. The mid-range can reach 45-50℃, and the use time is about 3.5-4.5 hours. The low-grade can reach 38-45℃, and the use time is about 5-6 hours. (Note: This heating temperature is tested when the ambient temperature is 10-15℃, the actual heating temperature of the product will also decrease with the decrease of the ambient temperature)Electrical parameters:Insole battery voltage: 3.7V Insole battery capacity: 1800mAWorking voltage range: 3.0V-4.2V Charging cut-off voltage: 4.2VDischarge cut-off voltage: 3.0V Battery life: 500 cycles or moreCharger parameters:Charging method: Constant current and constant voltage (CC/CV) Charging temperature: 0℃～45℃Input: AC/100-230V 40-60Hz Output: DC5V 500mA*2The DC head specification is: Φ0.7*2.0mmInsole size:Large size: 41-46 code segment;Small code
