  • Celestron's most compact, lightweight, and portable lithium power pack.
  • The built-in 12-volt regulating circuit Provides your telescope with up to 8 hours of consistent power at the proper voltage for optimum telescope performance.
  • It comes with a rapid charge USB port for fast-charging your electronic devices in the field.
  • It meets current FAA carry-on baggage regulations.

    Product Details

    • The Celestron PowerTank Lithium LT powers your telescope anywhere! This handy device is the smallest and lightest lithium-ion power pack. It's a must-have for your telescope and accessories, camping gear, emergency kit, and more! 

      Stable Power Designed for Telescopes

      The PowerTank Lithium LT is built with Lithium Nickel Manganese Cobalt Oxide [LiNiMnCoO2] or NMC technology, which delivers a steady charge over long periods and requires less maintenance than a traditional sealed lead-acid battery.

      The PowerTank Lithium LT uses a built-in voltage regulator to ensure that it delivers at least 11.8 Volts for most of the life of the battery until the battery is depleted and shuts off.

      The built-in Voltage regulator keeps your electronics safe by ensuring a stable 12V output, regardless of the amount of charge left in the battery.

      The NMC chemistry provides the PowerTank with a longer shelf life and three times the number of charge cycles than LiCoO2 chemistry! It also offers overcharge and over-discharge protection and can withstand temperatures 100° F (60° C) higher than LiCoO2 batteries making the NMC less likely to experience thermal runaway. 

      Use in the Field

      The power pack’s extremely portable form factor means it can go anywhere from a remote dark sky location for astro-imaging to a weekend of camping. When it's powering your telescope, use the included 2-inch straps to secure the unit to your tripod leg where it is out of the way. Besides the power cable to charge your telescope, no other cables are needed.


      If you need to power your telescope and charge electronic devices simultaneously, the PowerTank Lithium LT features two output ports: 1 12V DC port for the telescope and 1 fast-charging 2.1A USB charging port for smartphones and tablets. This USB port can also support any accessories that require 5V USB power.


      Travel with the PowerTank

      The PowerTank Lithium LT can travel with you on your next vacation. At 73.3 watt-hours, it meets current FAA regulations (160 Watt-hours) for transportation in your carry-on baggage. Please check in advance with your airline to verify they do not have stricter policies. Do not place PowerTank Lithium LT in your checked baggage.

    Great product

    Very light weight, lasts a long time. But if you need 5amps instead of 3 amps, choose another product.

    Used it to power my CPC1100. Nice not to have the hassle of a power cord. Still has a full charge after limited use. Plan on using it to power my Nexstar 8”as well.

    Smooth Power

    The Lithium LT power tank is light weight, and convenient. It is much better than having an extra wire coming up from the ground. On my Se-6 mount i have been able to attach it to the fork arm so there is no wire wrap of any kind. For the average amateur astronomer, the Lithium LT is well worth the purchase price.
