Works OK

Celestron Power Tank Lithium 18771

I am extremely pleased with my purchase of the Celestron Power Tank Lithium! Compared to battery packs of the past, it is much smaller, lighter, easier to handle and safe to use. I have been observing the night sky for many years now, and would highly recommend the Celestron Power Tank Lithium.


It was great, quick delivery

Works great.

If you are buying a NexStar telescope, do yourself a favour and add this power tank to your list. The 8SE devours AA batteries, so I learned to not even bother with them. Once I figured out that the power tank needed to be turned on to power my 8SE, things went a lot better. I’ve used it for several viewing sessions now and I still have 3 lights on the level indicator.

Power At Your Fingertips

You will never have to worry about having the battery power needed for a late night of gazing into the Dark Sky. This battery does the job and then some. It is easy to carry with its sturdy case that can survive a fall. It has a choice of two lights to assist you while visiting the Dark Sky Reserves in our beautiful province.
