Overview: With the Celestron PowerTank portable rechargeable
power supply, you can take your computerized or motor-driven telescope virtually
anywhere. In addition, you can power or charge your electronic devices,
including your phone, music player, or portable GPS. The PowerTank also includes
an emergency light, bright LED spotlight, and booster terminals for starting
your car if it has a weak battery. The PowerTank weighs 8.4 pounds.
Built-in Battery: The PowerTank contains an internal
12-volt, 7 Amp-hour rechargeable lead-acid battery. It charges in approximately
8 to 10 hours during normal use, however, the initial charge should be 14-16
hours. The included 110V/220V switchable universal AC adapter has four adapter
plugs, including those for the United States, United Kingdom, Europe, and
Australia. Four LED battery indicators are provided to show when the battery is
Fully Charged, Charging, Needs Charging, or Ready to Use. For safety, the
PowerTank has a 10A circuit breaker and a 2A fuse.
Outputs: The PowerTank provides two 12-volt 10-amp cigarette
lighter ports, each with a sliding cover. Celestron computerized and
motor-driven telescopes are powered through these outputs, using the included
11.5' power cords. (The DC power cords have a cigarette lighter adapter on one
end and a barrel-type DC power connector on the other end.) Also included are
two Type A USB ports (5-volt, 1.5-amp output) that can be used for charging
small electronic devices, such as cell phones, digital music players, and
digital cameras. Two screw-type booster terminals are provided on the back that
allow you to use the PowerTank as a vehicle starting aid, when the vehicle's
battery is partially discharged. It is not designed to start a vehicle with a
completely dead battery.
Flashlight/Spotlight: The Celestron PowerTank can be used as
an emergency roadside accessory. It has a standard flashlight with a 4.8-volt
Krypton bulb with a 3-way push button switch with constant on, flashing, and off
positions. It includes a red filter cap that can be used for emergency purposes.
The PowerTank also includes a large, powerful spotlight with 30 bright white
LEDs. The head of the spotlight can tilt over 90 degrees to one of nine
Storage Compartment: The PowerTank includes a storage area
that can be used for power cords and adapters. The compartment is 4.675" x 1.75"
x 1" with a hinged door.
