  • Celestron PowerTank 17

    The Celestron PowerTank 17 delivers a substantial 204 Wh of rechargeable power to run your computerized telescope for hours of uninterrupted observing or imaging. Its primary 12VDC car battery adapter port supplies a robust 10A, while two separate USB ports provide 1.5A each for charging essential accessories. Weighing 17.5 lbs, this unit is built as a stable power foundation for your entire setup, capable of operating in extreme temperatures from -40° to 140°F.

    204 Wh Capacity: Power Your Mount for a Full Night

    The core of the PowerTank 17 is its large-capacity 204 Wh battery, engineered to run any Celestron computerized mount from dusk until dawn. The primary output is a tip-positive 12VDC car battery port that delivers up to 10A, more than enough current for even the most demanding GoTo slews. An included 10 ft (3 m) power cord ensures you have ample room to position the battery away from your immediate observing area to prevent accidental bumps in the dark.

    Beyond Power: Integrated Red and White LEDs for Site Safety

    The PowerTank 17 integrates essential lighting tools directly into its design. A built-in red lensed LED flashlight allows you to find accessories or consult a star chart without ruining your night vision. When the session is over, a powerful white LED spotlight illuminates your entire observing area, ensuring you can pack up your equipment safely and not leave any small, critical parts behind.

    Field Utility: Dual 1.5A USB Ports and Emergency Radio

    This power supply is more than just a telescope accessory; it's a versatile field utility station. Two 5VDC USB ports, each outputting 1.5A, can charge your smartphone, tablet, or other electronic devices simultaneously. For added security during remote outings, the PowerTank 17 also includes a built-in AM/FM radio and a loud emergency siren, making it a valuable piece of gear for camping trips and emergency preparedness kits.

  • How long can the PowerTank 17 run my Celestron Advanced VX mount?

    With its 204 Wh capacity, the PowerTank 17 can typically power a Celestron Advanced VX or similar mid-sized GoTo mount for a full night of observing (8+ hours), including multiple slews and tracking. Actual runtime will vary based on temperature and the frequency of slewing.

    Can I use the PowerTank 17 to charge a laptop for astrophotography?

    No, the PowerTank 17 is not designed to power laptops. Its outputs are a 12VDC port rated at 10A and two 5VDC USB ports. Most laptops require a higher voltage AC or DC input that this unit does not provide.

    What is the purpose of the 12VDC 10A port on the PowerTank 17?

    The 12VDC, 10A car battery adapter port is the primary output designed to power your computerized telescope mount. It provides the necessary voltage and current for stable tracking and high-speed GoTo slewing. The PowerTank 17 includes a 10 ft cable that connects from this port to your mount's power input.

    How long does the PowerTank 17 take to charge?

    From a fully depleted state, the PowerTank 17 requires approximately 20 hours to reach a full charge using the included AC mains charger. It's recommended to charge it well in advance of your observing session.

    Is the Celestron PowerTank 17 waterproof?

    No, the specifications state the PowerTank 17 is not weather proof or dust proof. It should be protected from rain, heavy dew, and excessive dust to prevent damage to the internal electronics and battery.

    Does the PowerTank 17 come with a carrying strap?

    No, the specifications indicate that a strap is not included. Given its weight of 17.5 lbs, it's best to carry it by its integrated handle and place it on a stable, level surface during use.
