The Celestron PowerTank 17 is a portable power station designed for jump-starting vehicles, powering 12V DC devices, and providing 5V USB power. It also features a built-in flashlight, spotlight, radio, and emergency siren. Always ensure the unit is switched OFF when not in use and charge it fully before the first use.
Recharging the PowerTank
The PowerTank can be recharged via AC or DC power sources.
- AC Recharging: Select the correct adapter plug, set the main switch to the CHA position, and connect the AC adapter to the side panel input. Charge for 15-20 hours initially, and 10-12 hours for subsequent charges.
- DC Recharging: Use the provided DC power cord to connect to a vehicle's cigarette lighter. The engine must be running to initiate a charge.
- Important: Do not exceed recommended charging times. If the yellow LED light is on during operation, the battery is low and requires immediate recharging.
Using the PowerTank
- Power Supply: Ensure your devices match the PowerTank's rating (10A for 12V, 1.5A for 5V). Switch the unit ON before connecting your device.
- Flashlight & Spotlight: Use the ON/OFF button to cycle through modes. The flashlight can be detached for remote operation.
- Radio & Siren: Turn the volume knob clockwise to turn on the radio. Select AM or FM. To use the siren, turn the selector to the SIREN position.
Jump starting a vehicle
The PowerTank is intended for vehicles with partially discharged batteries.
- Ensure the PowerTank is OFF or ON as needed.
- Connect the POSITIVE (+) pole of the PowerTank to the POSITIVE (+) pole of the vehicle battery.
