Celestron 18771 overview

  • 1Description

Employing a more environmentally-friendly battery chemistry than previous iterations Celestron's PowerTank Lithium 86.4 Wh Power Supply gives you the power required to run your motorized Celestron mount with the added capability of charging small electronics such as smartphones, tablets, and cameras. An integrated white LED flashlight, with two output settings, gives you the illumination you need to get to your observation point and set, and a separate red LED light allows you to perform tasks like swapping eyepieces or attaching filters without affecting your night-adjusted vision. The PowerTank has a compact form factor at 7.5 x 3" and weighs in at just 2.25 pounds. Two straps are included so you can either hang it or attach it to the tripod, but if you want to leave it on the ground it has an IP65-rating making it dustproof and water-resistant.

    Celestron 18771 reviews

    PowerTank Lithium 86.4 Wh Power Supply is rated 4.8 out of 5 by 9.
    Rated 5 out of 5 by from Useful and very practical Just every thing you would need for your astronomy observing sessions. Very practical and will last all night. Highly recommended.
    Date published: 2016-08-08
    Rated 4 out of 5 by from Cover broke after minimal use This is a generally favourable review, however I did encounter one issue after very limited use. The switches and LEDs on the one end of the tank have a flexible rubber cover that is attached to the body by two thin rubber extensions. Peeling the cover back exposes the switches and lights. The rubber extensions failed after only a handle of open/close cycles for the cover. The cover still works but it is no longer physically connected attached to the body of the tank. No big deal, but it is not supposed to be that way.

    Rated 5 out of 5 by from Works great for powering telescope. I've used this power supply several times now and it works as advertised. It ran my telescope for 4 hours with no problems. It recharged overnight and was ready for another 3 hours the next night. It is very light and being able to strap it the tripod leg makes cable management easy. The red light is a nice feature and plenty bright.

    Rated 5 out of 5 by from Pricey but we'll worth the investment. Lasts many sessions in the cold. So nice to not be running extension cords. Pricey but very much worth it! Attaches to the leg of the tripod and is outta the way too.
    Date published: 2017-01-22
    Rated 5 out of 5 by from Lots of Power The power tank works better than expected. If I get dew heater strips that will really test it. But so far it seems to be an over achieving unit. It powers my CGEM II mount and the Skyportal Wi-Fi for hours. It is important to note that to get the 12V outlet to work you need to push the battery switch on the panel twice. At first I thought I has a defective unit but then I read the instructions.
    Date published: 2018-09-12
    Rated 5 out of 5 by from Good accessory for Celestron Scopes I've been using a PowerTank Lithium for about 8 months. So far it has been reliable and can power my scopes (4" and 8") for several sessions without recharging. Even though I use my scopes frequently, I like the fact that the PowerTank doesn't deteriorate if left uncharged as some types do. The USB ports have proven useful since I use an iPad during most viewing sessions. The red light is useful and also makes its location clearly visible so it doesn't get kicked over when I leave it on the ground. I believe the connectors will only work with Celestron scopes. I don't know whether adaptors are available for use with other manufacturers. A couple of minor issues: The rubber cap on top doesn't open fully and its design gives the impression it would break off if forced too far. Also, it would be nice if the bottom piece were a soft rubber rather than hard plastic since I often place it on concrete floors. Otherwise, I think it's a great accessory that I'll be able to use for several years.

    Rated 4 out of 5 by from Useful but... Works as described. Why there is no DC out to power a Celestron mount is beyond me... only two USB out puts to power accessories; will have to try to find a USB->14V adapter. Red light is plenty bright.

    Rated 5 out of 5 by from celestron power tank After 3 hours of use,it still read over 13 volts. It is an excellent package. I just wish I could adopt it to a Mead product!
