## Description

Enjoy your telescope without batteries with this AC adapter! When using your telescope at home or near any wall outlet, you can enjoy hours of uninterrupted observing. Running your telescope off of AC power is hassle-free and much more reliable than other methods, especially in cool temperatures, when batteries can lose charge quickly. This 2 amp AC Adapter is compatible with the following Celestron computerized telescopes: LCM Series NexStar SLT Series NexStar SE Series SkyProdigy Series Advanced Series Advanced VX Series CPC Series CPC Deluxe HD Series CPC Deluxe HD Series—This adapter is sufficient for most visual observing with a balanced telescope. However, for astroimaging using additional equipment, the 5 amp adapter (product #18780) is recommended.

Review: Works OK for low power set up - Not recommended if you have powered accessories. Need 5 amp
Review: Celestron NexStar 6SE Power Cable - Just what I needed, for the best price out there - My original plug for my Celestron NexStar 6SE was broken years ago as my telescope was slewing around and the cable wound up and it ripped itself out of the socket, Oops. Since then I have just used batteries in the Telescope but it has not worked well and the auto-tracking abilities were pretty much lost since the batteries didn't supply enough power to the telescope reliably. Finally got this plug and wow, I had forgotten how much of a difference it made. Glad I found this on desertcart since the price was more affordable, shipping was free and fast, and now my telescope works as intended. It is nice too that it comes with so many different types of plugs, I'm just in the USA so my plug is just for standard American outlets but it comes with a bunch of European style plugs too.
