Telescope power

Celestron PowerTank Lithium

This may sound a little strange, but I was pretty excited when our Celestron shipment showed up this week.  In it was Celestron’s new PowerTank and it is one you can really get charged up about.

Until now, if you wanted to get a power supply to run your telescope you were limited in your choices. Celestron made two, and all were wet cells. While they worked great, they were heavy and a little cumbersome but most importantly could not be fully drained of a charge.  If they were fully drained they would no longer hold a charge and became just a big heavy door stop.

Over the years at the store, in the field or at trade shows we would have to make sure we turned off the Power Tanks at the end of the day and diligently remember to charge them.

Otherwise, dead tank.

Celestron’s new PowerTank is power by a lithium battery. It lasts up to 10 hours when used with a scope, and up to 25 hours if you just want to use it for light (it offers both white and red light). It also has a couple of USB ports so you can charge other devices like a tablet or phone.

The other thing I like about it is the size.

Unlike the wet cell power tanks this one is relatively small and lightweight. The smaller size and weight makes it possible to strap the to one of the legs of your telescope—no more tripping over it in the dark.

Oh, and I almost forgot—you can charge and discharge this battery pack more than 2000 times. This is a power source that is going to last just as long as the telescope you are using it with.

We received a limited supply (more to come) but if you’d like to grab one drop by our Dartmouth store for a look and a demonstration.
