Celestron PowerTank

The PowerTank is compatible with most computerized telescope mounts that require a standard 12V DC power source. If your mount uses a standard cigarette-lighter style plug or a compatible adapter, this unit will provide the necessary power for your sessions.

Battery life depends heavily on your specific equipment and how much power your mount draws while tracking or slewing. For most standard computerized mounts, 17 amp-hours is sufficient to power a full night of visual observation or imaging without needing a recharge.

At 17.5 pounds, the PowerTank has some heft, but it is designed for portability. It is sturdy enough to handle field use, though you will want to account for its weight when planning how far you need to carry your gear from your vehicle.

Yes, the integrated USB ports are designed to operate alongside the 12V DC output jacks. This allows you to keep your smartphone or tablet charged for star-charting apps while your telescope mount remains powered.

The red-filtered flashlight is essential for maintaining your night vision. Red light is much less disruptive to your eyes than white light, allowing you to read star charts or adjust equipment in the dark without needing to wait for your eyes to re-adjust to the night sky.

Yes, the unit comes with an AC mains charger for wall outlets and a car battery adapter cable. You have multiple options to ensure the battery is fully charged before you head out to your observing site.
