    Product Description

    Keep your telescopes, smartphones, tablets, GPS systems, cameras and other USB-powered devices charged and ready with PowerTank Lithium—the ideal outdoor portable-charging solution. Celestron specially designed this product with the needs of amateur astronomers in mind; it’s packed with useful features. First, you’ll find a 12V connection for your Celestron telescope—no cigarette lighter port needed. Once your telescope is connected, attach the battery securely to one of the tripod legs with the included Velcro straps so it is safely out of the way. Two USB ports, one quick-charge and one regular, keep your other devices charged, and can be used simultaneously with the telescope charger. When your eyes are dark adapted, use the red LED flashlight to navigate your observing site without sacrificing your night vision. When the 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. PowerTank Lithium’s unique Lithium-Iron Phosphate (LiFePO4) battery chemistry has significant advantages over other battery chemistries. It will last you many times longer than sealed lead acid or lithium cobalt batteries thanks to its un-recharged shelf life of 10 years and 2000 charge cycle lifespan. It’s also better for the environment, free of toxic heavy metals like cobalt and lead. But most importantly, LiFePO4 can withstand higher temperatures than standard lithium cobalt batteries and will not be a fire danger if accidentally punctured. All this combined with its rugged design make PowerTank Lithium the perfect outdoor power supply.

    A must have accessory for the Celestron Nexstar line of scopes
    Must have product for the Nexstar series. Why? Because the 6 AA batteries do not output the required amount of voltage for very long resulting in odd behavior -- for example instead of slewing to an object, it will slew straight to the ground or it doesn't respond at all. Enter the Lithium power tank. It really does power the scope for 10 hours and at the required voltage. Your scope will not run out of power and more importantly, work as designed. The PowerTank also has USB ports and a red/white flashlight with a high and low brightness settings (low brightness red when your observing and the bright white when your done and breaking everything down). I secured my powertank to the fork arm so I never worry about annoying cord wrap when the scope is slewing to objects.

    Reviewed in the United States on January 5, 2023
    Verified Purchase
    When I bought my NextStar telescope, I figured I'd get by with just disposable batteries, but soon learned that that might have been an error. I bought this to save on batteries, and it works. It is easy to use, provides consistent power to the telescope, and as a bonus, has a red/white led to illuminate the area if need be. It is not what I'd consider "light" weight. If you dropped this on your bare toe, it would no doubt break it. It does does come with a strap to attach it to a tripod leg, and another strap that can be used to attach it just about anywhere, so you can place it somewhere safe and out-of-the-way. Weight aside, I only wish I had bought it earlier.

    To begin with I want to say that I highly recommend this power pack its lithium and as we all know when you make power packs with lithium battery they're smaller more powerful and they last longer, I was quite impressed with its size its functional features you can use it as a light you can charge a mobile phone if you run out of power and it has a red light in case you need some lighting there in the dark for setting up your telescope without having to disturb others or stargazing, overall it may cost a little bit more than the other power tanks I would suggest save a couple of more bucks and definitely get this one you will not regret it.!!!

    It powers my telescope for hours! I was a little skeptical at first but it really did its job - for several hours. Recharging time was roughly what the instructions said so it doesn't take too long for such a capable battery. The red light is a little bright if you look directly at it, but it didn't ruin my night-time vision. It works well to illuminate your entire working area.

    Yo la compré para energizar mi Nexstar 130 slt y es muy buena para observaciones en lugares donde no hay acceso a la luz, también la uso para iluminarme en actividades diarias por lo que es muy práctica. La batería es más que suficiente para una noche de observación de 5 horas o más no van a tener problema

    Unfortunately the battery doesn't come with an adapter that suits standard western European wall sockets - contrary to what is shown in the picture and in the manual!

    Even though I have bought the fitting adapter, battery doesn't charge which seems to be relatively common problem based on other reviews here and numerous forums in the field of amateur astronomy.

    Man bekommt einen massiv verbauten Akku. Ich betreibe ein C6 mit Standardmontierung und mache über die Stromversorgung der Goto keine Gedanken. Ein Manko ist der Preis, dafür steht Celestron darauf ;-)

    I purchased this to replace my old Meade LXPS7 power pack. This new one charges faster, straps easily to the leg of my Meade ETX 90 telescope and works a treat. hours and hours of use. very happy with it.
