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:

1. 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.

2. Plug the AC charger’s cable into the 12V DC port on
the power pack.

3. 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 I NDI CATOR 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.

ENGLISH I 3

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 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:

1. 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.

2. Wrap the strap around the tripod leg, then feed the end
of the strap through the buckle.

3. Pull the strap so it is tight against the tripod leg, and
secure the strap using its hook and loop fastener.

ENGLISH I 5

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.
