OPERATION OF POWERTANK LITHIUM
Charging the Battery
1. Determine which AC plug adapter you need for
your location and slide it into place on the
charger body. Make sure it is fully seated and
snaps into place.
2. Pull the rubber cover from the charging port on
the side of the PowerTank Lithium and plug in
the charger’s cable.
3. Plug in the charger to your electrical outlet. The
adapter can accept an input of 100 to 240V
at 50/60Hz.
4. The Battery Indicator lights will blink when
charging. When charging is complete, all of the
lights will remain lit.
NOTE: If you are traveling internationally with this device,
it may be necessary to change to a different plug adapter.
Simply depress the locking button on the charger (located
directly below the plug), slide the plug adapter off and
replace it with the adapter you need.
Warning: The charger has an output of 16 Volts DC. Do
not attempt to use this charger to power your telescope
directly or significant damage to your telescope will result.
Checking the Remaining Battery Charge
Press the power button once and the battery indicator
lights will light up showing the amount of power left in the
battery. All four lights means the battery is full, 3 lights is
75%, 2 lights is 50% and 1 light is 25%.
Charging USB Devices
Lift up the rubber seal on the top surface of the PowerTank
Lithium to expose the control panel. Plug one end of the
USB charging cable that came with the device you wish to
charge into one of the two USB ports on the PowerTank
Lithium. Plug the other end of the cable into your device.
Press the Power button on the control panel once to begin
charging. A green light will appear next to the USB port
showing that the power is flowing. The charger automatically
shuts off when the load drops below 100mA for
1 hour. If you want to end the charging session early,
simply unplug your device’s cable from the power supply.
Some devices, such as tablets and GPS devices require
more current to charge than other devices such as cell
phones. The PowerTank Lithium offers two 5 Volt DC
ports with current outputs of 1 Amp and 2.1 Amps.

ENGLISH I 5
Choose the port that works best for your device. Consult
the literature that came with your device if you are not sure
which to use.
Powering a Telescope
Pull the rubber cover from the charging/power port on the
side of the PowerTank Lithium and plug in the telescope
power cord. The cord has identical connectors on both
sides so it does not matter which direction it is used. Press
the power button on the control panel twice to activate
power. The battery indicator lights will blink in sequence
to show that power is flowing.
Illumination
The LED light panel can be used with red or white light.
Red light will allow you to see in the dark while protecting
your night vision. White light can be used when protecting
your night vision is not important.
To activate the red LEDs, press the lighting control button
once. To increase the brightness, press the button a
second time. To turn it off, press it a third time.
To activate the white LEDs, press and hold the lighting
control button for two seconds. To increase the brightness,
press the button again. To turn it off, press and hold the
button for two seconds.
ATTACHING THE POWERTANK LITHIUM TO YOUR TELESCOPE
The PowerTank Lithium can be set on a telescope accessory
tray in either horizontal or vertical orientation. It can also
be attached to a tripod leg by using the 2.5 inch wide hook
and loop strap. Slip the strap through the two slots in the
tripod leg mount. Start by wrapping the strap around the
tripod leg, then feeding the end of the strap through the
buckle. Pull the strap back and secure the hook and loop
strap to the desired tension.
You can also hang the PowerTank Lithium from any of the
anchor points in either end cap via the clips on the hanging
strap. It can be hung in any orientation – vertical, horizontal,
or even inverted.
