Power your telescope anywhere with the PowerTank Lithium LT, our smallest and lightest lithium-ion power pack. This handy device is essential for your telescope and its accessories, your camping gear, your emergency kit, and much more.

Unlike other lithium-ion power packs in this price range, the PowerTank Lithium LT was designed for astronomers by astronomers—specifically for the unique needs of computerized telescopes.

Telescope electronics are very sensitive to voltage. Powering a telescope with a voltage lower than the optimal voltage can put strain on the motors with heavier loads and may even cause issues in the electronics. The PowerTank Lithium LT uses a built-in voltage regulator to ensure it delivers at least 11.8 volts for most of the battery's life until it is depleted and shuts off.

Celestron engineers worked hand in hand with the battery suppliers of the PowerTank Lithium LT to ensure it does not suffer from this performance drop. The built-in voltage regulator ensures a stable 12V output, regardless of the amount of charge left in the battery. This keeps your telescope's electronic components safe and performing well, allowing you to focus on astronomy.

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