Celestron 18763 PowerTank Lithium LT Telescope Battery Power Pack – Rechargeable Portable 12V Power Supply for Computerised Telescopes with 8 Hour Capacity / 73.3 Wh and 1 USB Port, Black

Great product, works very well as advertised. We use it specifically to charge astronomy gear and we would highly recommend it.

I really like this for my go to mount easy to set up and holds a lot of power.This one has a usb as well so you can use multiple items at once,I am goint to make a splitter cable to give me mutiple 2.1mm dc jack connections.This hibernates when not in use and once connected to your scope setup you simply press the orange circular power button and it automatically wakes up and powers on so very easy to use and when finished it simply goes in to hibernation mode and stays like this until you press the button.I would recomend this and i give it full marks 5 stars.

Trust celestron to play on words, its Lithium ferrite, its a LiFePO4 they are good basically a small leisure battery a very good one at that if you look after it comes with a 16v charger i changed it for a 5v sure it takes a lot longer to charge but I will still have mine 10 years from now, batterys do not like fast charging and it will defo shorten the life of your celestron lithium ferrite battery 🤣🤣 its a LiFePO4 and you do need to keep your eye on them they dont like heat or extreme cold,LiFePO4 batteries offer a longer lifespan than lithium ion batteries, with the ability to last up to 10 years in the right conditions. On the other hand, lithium ion batteries typically last around 2-3 years. This is due to the chemistry and materials used in their construction. Of course, lifespan can also be affected by usage patterns, charging habits, and other factors, but the general consensus is that LiFePO4 batteries outlast their lithium ion counterparts.i hope this helps

This has a very good capacity and my use of it has not taxed it at all yet, although it has yet to be tested on a very prolonged observing session. The choice of lights is useful and so is the addition of the USB charging ports, although these cannot be used at the same time as the 12V output for the telescope, which is a small downside. The strap to attach to the telescope tripod legs is a little loose of the Celestron NexStar scope I own, but it is certainly still usable. Although anything which is attached by a cord to the movable mount of the scope needs care to be taken that it is not getting too wrapped up as you observe, this is not too onerous and is definitely preferable to the two choices of eating through AA batteries or having a long and inconvenient mains power cable/extension cord setup.

I now use this solely for my dew heaters but I could run my Nexstar 130 SLT for 6 hours without issue. I find that Celestron makes a lot of stuff which is cheaper than most so you can get started in amateur astronomy without taking out an extra mortgage. Don't be fooled by the price though as the quality of their products are excellent. This power bank is no exception and I definitely recommend it.

Celestron power tank li-on battery bank.Good robust build quality.Nice and strong.Works for upto 10 hours.Has built in light Red and White 2 power settings.Also 2 usb sockets.Comes with strap to attach it to tripod and one that clips to the top or bottom, but the way it attaches is very poor.Also the power tank has a lid the covers the USB’s and controls but this is rubbish very poor design must have used it about 20 times and it’s broke on one side.Little expensive.Would recommend it even though it little expensive very useful.

Torch simply didn't work. Input slot cover made of such flimsy plastic that it broke on first use. Returned for refund (and I certainly don't want another one of the same item). Shall buy a different red light torch. A pity, as I previously had a good impression of Celestron.

Just what I wanted to go with my telescope, fantastic battery life and good high battery capacity,thank you
