    Product Description

    Take your telescope anywhere with this portable, rechargeable power supply. Whether you have a computerized telescope or operate your telescope using motors, Celestron specially designed this product with the amateur astronomer in mind; it’s packed with useful features. First, you’ll find two 12V cigarette lighter ports for your astronomy gear. This battery is compatible with all Celestron computerized telescopes for maximum versatility. You’ll also find two USB ports on board so you can keep your smartphone, tablet, GPS, or speaker charged and ready all night long. When your eyes are dark adapted, turn on the integrated red LED flashlight to stay organized without sacrificing your night vision. When the observing or astroimaging session is over, turn on the bright white LED flashlight to illuminate your site and ensure no lens caps or eyepieces are left behind in the dark. When you’re not observing, keep this battery charged and at the ready for unexpected emergencies. You can use the flashlight and USB ports to stay illuminated and connected during a power failure. PowerTank can even help you top off a weak car battery with the included positive and negative terminals. This sealed lead acid battery offers safer and more stable chemistry compared to low-quality lithium ion batteries, and features a built-in circuit breaker for even more safety.

    3 out of 5 stars
    Decent product
    The battery and plugs performed as expected. Lasted the whole 8 hours of powering my telescope and a couple cell phones. My only issue is the red light. It broke within minutes with very little stress. I have to use my cell phone to see and deal with my eyes adjusting to the changes in light. The USB ports were unable to maintain my cell phone and had to use an adapter in the second 12 volt outlet to adequately charge my phone as I was using it as an eyepiece camera. The unit would benefit from a C-type USB outlet, and a threaded red lense instead of glued.

It's built well, has many different features (white and red flashlight, nice handle, multiple different connectors), and is much cheaper than many other power banks. I used it once and didn't observe any issues with it. Obviously, when it comes to any big battery, it's heavy (but that's to be expected).

    4.0 out of 5 stars Great unit! Terrible wall charger.
    Reviewed in the United States on June 15, 2017
    Size: PowerTank, 12v 7AhVerified Purchase
    Don't use the wall charger that comes with it! (only 4 stars because of the trouble with the wall charger, otherwise it deserves 5)

    I have had this unit for a year now and have LOVED having it. The red light is very useful for being able to see without ruining your night vision or disturbing other stargazers. The spotlight is awesomely bright and has come in handy when out in very dark places. I can run my Celestron Nexstar telescope on the unit (while using the red light) for several hours.

    The only problem with this unit? The wall charger sucks more than a Dyson vacuum (and Dyson's have a ton of sucking power ;-). Following the instructions I plugged the unit in to charge it before initial use, after 72 hours of being plugged in the charge was still not full. I did a quick troubleshooting search and everyone said the same thing, the wall charger is useless. We were heading out of town to a dark sky park so I didn't have time to get a different charger (many people recommend using a Battery Tender or an NOCO Genius G750 charger) so I plugged in the car power cord (it goes in your car's power terminal) and charged the battery that way on our trip, the unit was fully charged before we got to our destination. Thinking that maybe it needed the extra boost from the car to get it's initial charge up and going (and disbelieving the online reviews) from then on I only used the wall charger. The unit never said that it was at full charge but I figured if I followed the guidelines of topping off the charge every month, charging before use, and charging after use that everything would be ok. Enter 4 days ago when I went to charge the unit for use and it wouldn't charge, again 72 hours of being plugged in and the "needs charging" light was still on. Again I had to take it in my car with me and charge the unit up, worrying that after a year of never being charged up I had completely killed the battery, thankfully it charged just fine in the car. I have now purchased the NOCO charger (as it had the most recommendations on forums) and will never again use the wall charger that came with the unit.

    Reviewed in the United States on May 19, 2015
    Size: PowerTank, 12v 7AhVerified Purchase
    Well, it looks like a tank anyway.

    I camp out a lot. As such I've grown to appreciate having a power box available for the times I'm plop-camping (or "glamping"). I used to take a jump box with me, but I always felt a little funny (and inefficient) about something with attached jumper cables.

    Enter the Celestron Power Tank. Yes, it's intended to support the use of a telescope. But it can do oh so much more.

    For instance, there are two cigarette lighter plugs (I'm old enough where I can call them that). Plug in a suitable power inverter and you have a power outlet you can use to, say, inflate an air mattress. Two USB ports lets you charge your stuff. And there is a mack daddy spotlight on it.

    So it works. And as there are a two terminals on the back, with jumper cables I could theoretically use jumper cables with this. I also appreciate the off/on/charge switch...it makes it very clear what I'm doing, and it enables me to keep the unit plugged in without charging it. This is important as the instructions tell you to charge it regularly when in storage. Much easier to flip a switch while it's already plugged in, instead of unraveling a charging cable (after you spend twenty minutes looking for it) and plugging it in.

    The light is quite bright and can angle down. I really kind of wish it angled in all directions though, as I was using this as a tent light (and thus pointed straight up) but it kept tipping.

    Charging this at first use is unclear - on one hand (the printed directions) you're told to charge it for 14-16 hours out of the box, but on the unit itself you're told to charge it for 24 hours. You are then cautioned against overcharging it lest explosive gasses are generated and it explodes or something.

    Your takeaway - this is a easy to use and solid performer for times when you need a versatile power box. It's not overly heavy as jump boxes tend to be, it has a clever on/off/charge switch, and the light is plenty powerful for normal use. This is a winner.

    5.0 out of 5 stars GREAT BUT NOT VERY LONG LASTING
    Reviewed in the United Kingdom on July 20, 2022
    Size: PowerTank, 12v 7AhVerified Purchase
    Bought two of these (£43) in Jan 2007 to run my telescopes etc. They were excellent, plenty of power to run LX8 and LX12 and lasted most of the night. Very easy to charge, great to have a fuze as a safety backup as well, yes they took a few hours to charge but with two I never encountered any problems.

    Unfortunately, the first one stopped accepting a charge back in early 2011 and the second in 2014. The 2014 one, nearly 7 years I though was reasonable but not the 2011, less than four years seemed far to short a lifespan. I still have them both as bricks in my shed, can't bring myself to dump them. :-)

    Reviewed in Germany on February 8, 2021
    Size: PowerTank, 12v 7AhVerified Purchase
    Ich verwende den PowerTank für mein Teleskop zur Stromversorgung der Montierung und der Heizmanschette. Der PowerTank hat 2x 12V Zigarettenstecker Ausgänge und 2x USB Ausgänge für Handy, Laptop und dgl. mehr. Ein Kabel mit Zigarettenanzünder wird in einem Fach mitgeliefert. Das Fach ist allerdings etwas zu klein geraten und sobald das Kabel einmal verwendet wurde, passt es eigentlich nicht mehr rein. Ist für mich aber kein Problem.
    Die Rotlicht-Lampe ist bei astronomischen Beobachtungen sehr hilfreich. Der PowerTank hat einen praktischen Handgriff und es gibt auch einen Tragegurt dazu. Das Gewicht ist ok.
    Der Akku hält bei mir - trotz Außeneinsatzes bei Minusgraden - lange, meist länger als 10-12 Stunden. Den PowerTank gibt es ausführungsgleich auf von anderen Herstellern - der von Celestron ist allerdings am günstigsten.
