About this product

The Celestron Smart DewHeater and Power Controller 4X is a precision electronic device designed to prevent dew formation on astronomical optics during stargazing and astrophotography.

The unit includes four 12V DC power ports—one with variable voltage—and a USB 3.2 hub with three powered USB Type A ports for connecting imaging equipment and computers. It supports both Celestron Dew Heater Rings and third-party heating bands when used with a thermistor accessory. Designed for reliable performance in field conditions, it features a wipe-clean surface and is imported.
