PRODUCT OPERATION

CHARGING THE CUBE
AC Charging
The intelligent fast-charging technology of Wagan supports an AC input power of 1000W.
The smart charging system will preferentially harness solar power whenever the Lithium Cube is being recharged simultaneously by AC power and solar power.
e.g.
During simultaneous solar and AC charging, if the solar power is 300W, it will automatically adjust the AC charging to 700W. If the solar power rises to 600W during the midday sun, the Lithium Cube will drop the AC charging to 400W to make maximum use of solar power. Please use the official Wagan cable for AC charging. Using the supplied AC Charging Cable, plug one end of the cable into the AC Charging input port on the back of the Lithium Cube, then plug the other end of the cable into an AC Wall outlet that supports a current of 10A or greater.
Wagan is not responsible for any damage caused by using an unofficial charging cable or operating the product outside of specifications.

DC Charging
The DC charging cable is fused at 10 amps to prevent damage if there is an inadvertent short.
Users can charge the product through the cigarette lighter port. Be sure to start the vehicle before using the DC Charging Cable to reduce the risk of depleting your vehicle’s battery.
To charge the Lithium Cube using the DC Charging Cable:

ONLY USE THE DC CHARGING CABLE SUPPLIED WITH THIS UNIT.

1. Note that the engine must be running while charging the Lithium Cube to avoid discharging the vehicle’s battery.
2. Plug the DC charging cable into the Lithium Cube’s DC Anderson input port.
3. Plug the other end of the DC charging cable into the vehicle’s accessory socket (cigarette lighter socket).

Solar Charging
The Lithium Cube’s DC input circuit is designed to maximize the charging profile based on the available power supplied, whether charging by the AC charger or solar panels via the Anderson port.
The Lithium Cube comes with a built-in 25A MPPT solar controller capable of charging up to 600W. Do not use solar panels with their own built-in solar controller. Wagan is not responsible for any damage caused by using an unofficial charging cable.

1. To charge the Lithium Cube using a single solar panel, connect the solar panel using an Anderson connector compatible with the one built into the unit. The charge status will update on the display automatically.
2. To charge using multiple panels, the best way to do this is by connecting the panels in series.
3. The Wagan Series Solar Cable is wired to connect multiple panels in series. If only two panels are connected, you must connect the jumper cable to the third cable set in order for the panels to charge. You can connect this cable to any cable set on the panel side of the cables.
4. When connecting three panels, the jumper cable is not needed. Keep this jumper for future use.

Note: Multiple solar panels with a total voltage of 70V can be connected in series. The maximum wattage of solar panels is 600W. (Cable and Solar Panels sold separately)

OUTPUT POWER

Before using the Lithium Cube, please make sure the main power has been turned on.
AC OUTPUT
The Lithium Cube’s inverter can operate most AC Appliances or a combination of appliances up to 1,800 watts. Operating time (run time) is dependent on the AC load (watts) and the charge and condition of the Lithium Cube’s internal battery. Be sure to turn off or disconnect any AC appliance not in use.
Converting DC battery power to AC generates heat. To minimize heat buildup and possible thermal shutdown, remove obstacles blocking or hindering airflow between the intake and exhaust sides of the Lithium Cube. Ambient temperatures above 77 ºF will reduce the Inverter’s abilit y to cool effectively, thus affecting operating times.
This inverter produces Pure Sine Wave (PSW) AC, which mimics the same power coming from your wall outlets at home.

To use the AC Power Inverter:

1. Connect the AC appliance or appliances to any AC Outlet.
2. Turn the power inverter ON by pressing the AC power button.
3. Turn on one AC appliance and observe the power indicator.
4. After appliance use, turn OFF the AC power button.
5. Remove AC appliance plug(s) from the AC outlets on the Lithium Cube.
6.  Recharge the Lithium Cube as soon as convenient.

Note: The cooling fan turns off and on when needed to keep the internal components cool. The cooling fan helps maintain the Lithium Cube’s internal temperature when products with high power requirements are in use.

PARALLEL POWER CONNECTION
With Wagan’s parallel stacking technology, users can parallel connect two Lithium Cube Power Stations via the Parallel Cable for a maximum power capacit y of 2880Wh of AC power and get a continuous power output of 3600W from the AC Outlet of the Parallel Cable or 2400W from the AC Output ports of the Lithium Cube.

1. Before connecting the two Lithium Cubes in parallel, make sure that the AC Power Buttons of both products are kept off and are NOT AC charging.

2. As shown in the diagram below, ground terminals, positive terminals and negative terminals of the Parallel Cable and the Lithium Cube need to be connected to each other.
   For firm contact, make sure the parallel connectors of the cable are fully plugged into the parallel ports of Lithium Cube. Please notice the positive and negative terminals are distinguished by their color.

3. Once the two Lithium Cube Power Stations are connected, turn on the AC Power Button on each unit, and you can charge electrical devices through the AC output socket on the Parallel Cable.

*Real-time AC output wattage shows on both units, indicating a successful connection.

Notice:

1. For parallel connections, please use Wagan’s official parallel connectors. Wagan will not be responsible for any safet y accident resulting from the use of cables not approved by Wagan.
   **** To prevent electric shock, please do not plug any conductive objects into the parallel ports.

2. Please make sure that the AC output is off before connecting the two units in parallel.
   **** If the AC output has been turned on before plugging the parallel connectors, it is possible to generate electric sparks and damage the parallel ports.

3. Please note that when the Lithium Cube is in UPS mode, the parallel connection is automatically disabled.

4. Upon connecting the two units in parallel, one unit with lower power will automatically shut itself down when its power is exhausted, which will disable the parallel connection and return the AC output to 1800W.

UNINTERRUPTED POWER SUPPLY (UPS)
The Lithium Cube support UPS. After plugging the Lithium Cube into the grid power through the AC Input Port, you can charge electrical devices through the AC Output Ports of Lithium Cube (In this situation, AC power will come from the grid rather than the Lithium Cube).
When a sudden blackout occurs, the Lithium Cube automatically switches to uninterrupted power supply mode within 10ms (Milliseconds). Electric devices can automatically be charged by grid power after the grid power is restored. Wagan’s Lithium Cube supports an uninterrupted power switchover mode.
UPS Care Technology will protect against overload if Lithium Cube is used in UPS mode when charging devices that exceed 1800W.

Note: The UPS of the Lithium Cube does not support 0ms switching. Please do not connect it to any device that requires 0ms UPS, such as data servers and workstations. It is recommended that you test and confirm the compatibilit y of Lithium Cube with your devices before using the UPS function. To avoid overload protection, we recommend only charging one device at a time rather than using multiple ones simultaneously. Wagan takes no responsibilit y for any device failures or data losses caused by failures to follow instructions.

DC OUTPUT
The Lithium Cube is equipped with 12V DC output ports to power various DC appliances via a standard DC socket or an Anderson power port (10A max shared).
Overloading the DC port will trip a safet y circuit. Remove the overload to restore power to the DC output ports.
CAUTION—Do not insert an automotive cigarette lighter into the socket. There is no pop-out feature and excessive heat may damage the socket.

To use an accessory outlet:

1. Insert the 12V DC accessory plug into either the DC port or Anderson port.
2. Press the DC power button. DC symbol should show on display.
3. Operate the appliance as usual.
4. After use, disconnect the accessory plug and store the accessory.
