Celestron18778 2 Amp AC Adapter - Powers Computerised Telescopes, Includes US/UK/EU and AU Adapter Plugs, Black

Good Celestron Quality and design, usable on several of their telescopes.

Works great to provide household current to Celestron Nexstar telescopes when an outdoor electrical outlet is available. Eliminates having to use and replace batteries.

This powered my Celestron Nexstar 5SE telescope yesterday for the whole eclipse. No problems. I was plugged into a Jackery battery also plugged into a solar panel. I had no power problems. As the telescope turns, I use a velcro strap to strap the wire to a leg with enough play so it doesn't pull tight.

Like a clutz, my foot caught my 12V car adapter plug that came with my CG5GT mount. I have pulled the plug out on other occasions but this one felt a little firmer and I heard a snapping noise. The wire had pulled out of the plug instead of the plug out of the socket. Not being able to find a replacement cord, I found this on Amazon. As batterys can provide the purest, cleanest DC, I had always used a simple power pack before. Since clear skys are far and between, I found the great weakness with these packs is either leaving them trickle charging constantly or risk your mount slewing slowly as the night goes on. Running a CG5 or other mount and using an astrozap system will tax these packs unless you keep them peaked up which I have sometimes forgotten to do.This adapter provides a steady stream of power ALL night long and after using it a few times I really appreciate it. The Orion nebula comes over the horizon at my location EARLY in morning at this time of the year so it makes it all the more likely my setup will be fully functional when it does come into view. I love it! But I still want a 12V car adapter plug for dark sites away from 120V outlets.

I had to replace my laptop charger because it was no longer working. I was concerned about ordering a new one on amazon without being able to test it on my laptop to be 100% sure it was the right one. Amazon made it easier by having the option of entering my exact laptop information & then it showed me a list of accessories that are for my laptop! I ordered it still concerned it wouldn't be the right one but to my surprise it fit PERFECTLY! The only issue I'm having with the charger is that the part that plugs into the wall & the part that plugs into my laptop keep becoming unpluged from eachother. This is why I didnt gove 5 stars.

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 Amazon 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.

I ordered the adapter so I wouldn't go through so many batteries when using our telescope at home. It was a great purchase and well worth it. As with many battery operated items, as the batteries get used, the device they power starts to slow down. This is the case with our celestron telescope. Not only does it slow down, when the batteries get to a certain point in their use, the star tracking functions stop working correctly. So, even though the 'scope has power to move, it's slow and and won't follow the star tracks. Not only that, but it won't even correctly star align on start up. But, with the power adapter, that's no longer a problem. The built in functions of the 'scope work perfectly and the 'scope moves with authority when changing from one object to another and correctly stays fixed on the object as it moves through the sky.Any drawback would be having to connect it to an electrical cord and make sure you don't trip over it, but that's a minor problem. I'd definiately recommend this to anyone with a 'scope.

Just got mine today, might update after a few uses today.I bought this and had it come in the same day as my Celestron SE4 because reviews said the batteries didn't last much longer then maybe 30 minutes and with it needing like 8, this was a much needed investment. Ive seen some people say the following, "the adapter in the picture is not the one you get" and that the cord or prong outlet holder thing isn't tight so you have to tape it down. As of right now on mine, it looks exactly like the image (a little bulky for an adapter maybe), the cord does not feel loose at all (yet), and the prong holder thingy just needs to be snapped in (you have to use slightly more then average force to get it in place). Again, I may update this after some use if I remember to.
