Scroll down the linked webpage to the listing until you find "NexStar Evolution". The manual is good to have on hand.

You mean a USB powered dew heater?
No. That USB port is intended as a charge tender for a smartphone or tablet, and cannot supply nearly the amount of wattage required for a dew heater for the optical tube.
Specs: Charge Port 5V, Max Output 2.0A -- 10W max.
An 8" Celestron Dew Heater Ring draws about 1.7A @ 12V, meaning 20W of power at full draw. Less when throttled with a PWM controller.

Thanks, I was planning on using external battery. Miss that in the manual.
