1. 5.5X2.1 female interface design,easy connected to various 12V power inputs;
2. Protecting optical equipment such as telescopes from fogging or freezing. Compatible with astronomical primary mirrors of OD below 152mm(178mm) or Camera Lenses;
3. Three-speed regulator with medium-weak heating mode. You can adjust the temperature according to different usage requirements. Super-fast continuous heating, quick start heating;
4. The width of the 50mm belt will not interfere with focusing, and will not produce vignetting in the field of view;
5. Great heat preservation effect: imitating OK cloth, SBR, and Black-T three-layer heat preservation material, reducing heat dissipation, and no wrinkles on the inner surface after bending;
6. Uniform heating: the built-in aluminum film has a uniform heating surface and no dead ends;
7. TPE Silica power cord under low temperature won't become hard, also prevents internal short circuits.
