I bought this cable to replace the one that came with our CPC 925, which we use with a 20AH field battery. The original power cord failed after two years, developing an intermittent connection where the wire enters the plug housing at the telescope end. This was especially annoying because I always loop the cable thru the fork arm handle to provide extra strain-relief, so the original cable was never yanked or stressed at the point where it failed.

This new cable is made a bit differently, so I won't know if it's better or worse until it's been through a couple of temperature extremes. One difference is the type of cable used. The new one uses something similar to zip cord or speaker wire, while the original had both conductors enclosed in a round outer jacket that was softer and more flexible. The new DC plug is a straight type, rather than the right-angle plug on the original, which I liked. However, the new plug seems beefier and appears to have a much better strain-relief, so we'll see how well it holds up. The cigarette lighter plug is identical on both cables, except the new one lacks the original's red LED power indicator. Unlike the molded plug on the other end, this one can be easily removed & replaced, so I might swap them. I'll plan on updating this review after the new cable completes its first winter of use.

UPDATE (Feb 2015): I'm a bit late with this follow-up, but happy to report that after 5-1/2 years of regular use, this cable is still good-as-new. Just like the original cable that came with the scope, I keep this one wrapped on a Cordpro Mini Cord Organizer. This ensures it never gets tangled or dragged on the pavement. I also continue to loop it thru the scope's fork handle in a loose knot to provide extra strain relief in case the anti-cordwrap goes awry (or I forget to turn it on).

It must be noted that Celestron may be using a different supplier for this cable than for the one I purchased several years ago, so your mileage may vary. As Patrick Niemeyer mentioned in his comment below, the cable currently being offered does, in fact feature an LED indicator on the cigarette lighter end. The photo also shows a knurled locknut on the scope end, which my cable does not have. The locknut would not do anything for me, since the 12V jack on my CPC does not have any exposed threads and I'm not inclined to take the scope apart just to remount the jack. Still, if the new version of this cable proves as durable as mine, it would certainly be worth five stars. The price has also dropped several dollars since I bought mine.

I have a 8 inch SC scope. The Celestron Car Battery Adapter allows me to view for many hours without worry about running out of my base batteries. Now I can take very long photos of the heavens.. This is one great extension for night viewing.

This adapter along with the AC adapter gives Me the availability of House curent, and the use of a DC Power Supply for long night viewing.

If you travel with your telescope to different viewing locations you may want to buy one of these. i use my scope at different locations and my computerized mount uses 8 batteries to power itself. I bought this dc adapter to use instead of batteries. It has a really long cable so you can plug into your car and be a distance away from it to power your scope.
Works with specific Celestron Computerized mounts so check to see if it will work with yours before buying it

I use this to connect my truck backup battery to my telescope. It's nothing fancy, just a way to not waste money on AA batteries. It has plenty of length and appears to be capable of absorbing minor tripping.

One word of caution: Place your battery below the telescope so that this cord doesn't become a trip hazard in the dark. Also need to pay attention that you don't wrap the cord around the tripod.

This could have been a better product for my Nexstar 6SE. It does not insert fully and it keeps unplugging while the screw nut serves no function on the 6SE (hoping that it did). The solution is to wrap the cord around the base of the telescope a few times to prevent it from coming out. The cord is nice and long and the plug in had a LED light.

Not much to review about, but here's the skinny:

It's a well-built long cable with the right connector for your Celestron scope, and a car-adapter on the other end. Came with a twisty-tie.

This saved lots of time switching out batteries on a dark hilltop. We had to roll down the window to keep the car lights off. Otherwise, it was great and worked just fine!

This adapter is essential, especially if you're using the Power Bank.
I would recommend this to anyone with a Celestron Nexstar telescope.

Great cable. Note that mine (ordered January 2015) *does* include a red LED power light. The top review on the product indicates that buyer received a cable that did *not* have one and I believe this would be a really significant drawback. Otherwise, the cable is fine and probably plenty long to reach a car and have room for your telescope to slew round and round a few times.

I am using this with a JNC300XL external jump-start battery and very happy with that setup. The Celestron powertank looks like a fine product, though it strikes me as possibly overpriced. The JNC300XL + this cable is a bit more expensive, but I find that external, portable jump-start battery (or a similar one) a more flexible option for jump-starting a car and I was pleased to learn that it has a cigarette lighter behind its bulb.

I suspect this cable should be compatible with just about any external battery that has a 12v accessory power hookup, but it's working great with my battery for my Celestron Nextstar 6SE.
