Electric heated insoles with Warmspace battery will keep your feet and shoes warm even in the coldest weather. These rechargeable heated insoles are designed to keep your feet warm when you're outside during the colder months, perfect for working, walking, commuting, or enjoying the outdoors in the winter. The peculiarity of the model is a long operating time, fast heating and the ability to adjust the insole to the size of the shoe. Adjustment of length and size is carried out independently by cutting to the desired size. You can cut the insole to length yourself along the dotted line by choosing a size from 36 to 46, but no less than the line of the smallest size, since the outermost part of the heating element is located there. The insole thickness is only about 2 mm, so it is universally suitable for any type of shoe, regardless of instep and sole type. The heating element built into the insole is flexible and resistant to external influences. The insoles can be washed and wetted without damaging the internal structure. The insoles are powered by a built-in rechargeable lithium polymer battery with a capacity of 2000 mAh. This battery capacity is enough for 3-4 hours of uninterrupted heating. The built-in battery is charged using a cable from a conventional 5V power source. Attention! For charging, use only the original charger to avoid accidents and battery failure. Approximate full charging time is about 2 hours. Disconnect the batteries from the charger. Connect them using connectors to the insoles. Use only the supplied batteries to power the heating element of the gloves. For comfortable use, hide the batteries in the pocket. To stop heating, you can disconnect the batteries from the connectors and connect them again if necessary.
