CELESTRON 18763 Portable Power Pack
PowerTank Lithium LT is a highly portable power pack that uses a lithium nickel cobalt manganese battery and voltage-regulating electronics. It is engineered specifically for use with telescopes, as the consistent 12V DC output ensures optimal telescope performance as the battery is discharged. It also works great with telescope accessories and other electronics requiring 12V DC power. In addition, PowerTank Lithium LT has a fast-charging USB port for charging devices such as smartphones and tablets.
Please read through this instruction manual to understand the functions and features of the PowerTank Lithium LT.

OPERATION
CHARGING THE POWERTANK LITHIUM LT
We recommend fully charging the power pack when you first receive it and before first use. To maintain its performance, you should recharge the unit at least once every 6 months.
TO CHARGE:
- Determine which international adapter plug you need for your location and slide it into place on the AC charger. Make sure the adapter plug is fully seated and snaps into place.
- Plug the AC charger’s cable into the 12V DC port on the power pack.
- Plug the AC charger into an electrical outlet. The charger can accept an AC input of 100-240V 50/60Hz.
The battery indicator lights will blink when charging. When charging is complete, all the lights will remain illuminated. Fully charging the power pack can take up to 4 hours. Don’t leave the AC charger connected to the power pack for more than 24 hours.
If you are traveling internationally with the PowerTank Lithium LT, it may be necessary to change the AC charger’s adapter plug. To do this, simply depress the locking button on the charger (located directly below the plug), slide the plug off, and replace it with the plug you need.
WARNING:
The AC charger has an output of 16V DC. Do not attempt to use this charger to
power your telescope directly or damage to the telescope could result.
THE POWER BUTTON AND BATTERY INDICATOR LIGHTS
Pressing the power button turns the PowerTank Lithium LT on, and allows use of
the USB and 12V DC output ports. Both ports can be used at the same time. The
battery indicator lights will also turn on and indicate the battery charge
status:
- 4 lights illuminated – 100 % charged
- 3 lights illuminated – 75% charged
- 2 lights illuminated – 50% charged
- 1 light illuminated – 25% charged
The battery indicator lights will turn off after about 10 seconds. They will turn on again when a device is connected to one of the charging ports. When the battery is fully discharged, the power pack will automatically shut off, and cannot be turned on again until it is recharged. Press and hold the power button for one second to turn the PowerTank Lithium LT off. The power will automatically turn off if there is no load detected (less than 150mA) for one hour.
CHARGING USB DEVICES
Plug one end of the USB charging cable for the device you wish to charge into
the USB port on the PowerTank Lithium LT. Plug the other end of the cable into
your device. Press the power button to begin charging. When you are done
charging, press and hold the power button to turn the power off. You can also
simply unplug your device’s cable from the power pack, and it will
automatically turn off after one hour. The USB port provides 5V DC @ 2.1A
output, so it is capable of “fast-charging” devices that have this
functionality.
POWERING TELESCOPES AND OTHER ELECTRONICS
PowerTank Lithium LT comes with a power cable that is compatible with
Celestron telescopes. It can also be used with many other telescopes,
telescope accessories, and electronics that have a 5.5mm/2.1mm tip-positive
12V DC power jack. The cable has identical connectors; plug one end of the
cable into the power jack on your telescope and plug the other end into the
12V DC port on the power pack. Press the power button to activate the power.
Turn the power pack off by pressing and holding the power button. Otherwise,
the power pack will automatically shut off after 1 hour when no load is
detected.
The PowerTank Lithium LT is designed to supply a maximum of 3A. If the current draw is continuously greater than 3.2A, it will immediately cut off the output. The battery indicator lights will flash 10 times, then turn off. If a short circuit occurs, the power pack will shut off immediately and will need to be recharged before it will turn on again.
MOUNTING
ATTACHING THE POWERTANK LITHIUM LT
TO YOUR TELESCOPE TRIPOD
PowerTank Lithium LT can be attached to your telescope’s tripod leg using the
tripod leg strap. To use the strap:
- Slip the strap through the two slots in the power pack’s tripod leg mount. The hook and loop fasteners on the strap should be facing toward the power pack.
- Wrap the strap around the tripod leg, then feed the end of the strap through the buckle.
- Pull the strap so it is tight against the tripod leg, and secure the strap using its hook and loop fastener.
CARE AND MAINTENANCE
While the PowerTank Lithium LT has some weather resistance, it is not waterproof. Do not immerse the power pack in water. If it becomes wet with dew, dry it off with a towel after use. It is also best to keep the power pack off the ground, as this will prevent debris from getting into the ports.
The power pack is best stored at room temperature in a dry area. Make sure there is at least 50% charge on the battery when it is stored; recharge before storage if needed. PowerTank Lithium LT should be recharged at least once every 6 months.
