The SVBONY 400mm Lens Heater is an essential accessory for all astronomy and night photography enthusiasts. This universal device is designed to prevent fogging on telescope and camera lenses by warming the lenses, ensuring uninterrupted observation sessions. Additionally, it can also be used to heat a water bottle or as a knee strap, offering versatility in use.

Equipped with a USB port, this heater has a 1.8 m cable that allows it to be easily connected to a power bank or any other USB power source. With an input current of 1.9A to 2.0A and an input voltage of 5V, the heater offers efficient and convenient operation.

The temperature regulation is adjustable and offers three heating modes: low, medium, and high, so you can adapt the temperature according to your needs. Specifically designed for telescopes, the heater has a width of 50mm that does not affect the focus and does not create a dark angle in the field of view. It is compatible with lenses that have an outer diameter of less than 127mm.

This model features rapid and uniform heating capacity thanks to an aluminum construction that ensures even heat distribution. Its alloy heating wire provides quick temperature rise, while the three layers of insulating material reduce heat dissipation.
