OPERATION OF POWERTANK LITHIUM

Charging the Battery

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.
Pull the rubber cover from the charging port on the side of the PowerTank Lithium and plug in the charger’s cable.
Plug in the charger to your electrical outlet. The adapter can accept an input of 100 to 240V at 50/60Hz.
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.

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.

NOTE: The PowerTank Lithium can provide power from the 12 Volt output or provide power through the USB outputs, but not both at the same time.

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.
