Heating straps or heating bands are simply placed around the dew shield at the height of the optics and fixed with the flexible adhesive strap tape. Since the straps are insulated to the outside, the heating power is directed inward, toward the optics. The minimal heating prevents the precipitation of humidity.
The heaters have a USB plug and can be supplied with energy via a power tank or a power bank.
Please do not connect the heater to the USB port of your computer. The USB port is not designed for this and it can be destroyed.
