Celestron PowerTank Lithium 84.4Wh Power Supply

Employing a more environmentally friendly battery chemistry than previous iterations Celestron's PowerTank Lithium 84.4 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 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.
