Chicony 5 A 12 VDC AC Adapter for Celestron Mounts

This new AC adapter delivers up to 5 A at 12 VDC to compatible Celestron computerized telescopes. It is built for the CGEM II, CGX, CGX-L and CPC series when they carry heavy imaging loads. The switching design provides high output with less weight than a traditional transformer unit. A threaded barrel connector on the DC plug secures the connection against accidental cable pulls.

Astro-imagers adding cameras.

Visual observers with a balanced telescope only need the standard 2 A adapter (part 18778) and will not benefit from the extra capacity. This unit is not for telescopes outside the listed Celestron series or for any device requiring a different voltage or connector type. Buyers who need battery-powered portability should look at a suitable portable power pack instead.

5 A at 12 VDC with threaded barrel connector

The single specification that decides fit is the 5 A, 12 VDC output combined with the threaded barrel connector. It matches the power requirement for CGEM II, CGX, CGX-L and CPC mounts running heavy imaging payloads. Verify that your mount uses this exact connector and voltage before ordering.

Questions about this item

How do I connect the 5 A 12 VDC adapter to my CGX-L mount without it coming loose?

Plug the threaded barrel connector into the mount's DC input and twist the outer ring clockwise until it locks; the threads stop accidental pulls from breaking the power connection.

What part should I check or replace after a few years of imaging sessions?

Inspect the DC cable near the barrel connector for fraying or stiffness; if the insulation cracks or the plug feels loose when twisted, replace the whole adapter unit.

At what load does the adapter hit its limit during a long night of guiding and camera cooling?

The unit is rated for a continuous 5 A at 12 VDC; drawing more than 5 amps — for example with multiple dew heaters and a large camera — will trip its internal protection.
