NOTICE
NOTICE is used to address practices not related to physical injury.
3. PRODUCT SAFETY INFORMATION
� WARNING
Shock or fire hazard—The Power Cube generates the same potentially lethal AC power
as a normal household wall outlet. Treat it with the same respect that you would any AC
outlet.
Explosion Hazard—Do not use this product around flammable fumes or gasses, such as in
the bilge of a gasoline powered boat, or near a propane tank. Do not use the Power Cube
in an enclosure containing automotive-type lead-acid batteries. These batteries, unlike
the sealed battery pack in the Power Cube, vent explosive hydrogen gas, which can be
ignited by sparks from electrical connections or disconnections.
When working on electrical equipment, always make sure that someone is nearby to help
you in an emergency.
Limitations on Use—The Power Cube has not been tested for use with life support systems
or other medical equipment or devices. The user assumes all risk if medical devices are
used with this product.
Unit is Not Waterproof—Do not expose this unit to rain or heavy moisture.
Do not disassemble the product in any way or pierce the product with sharp objects.
During thunderstorms or stormy weather, please disconnect the AC charging or solar
charging. If the product is struck by lightning, it may cause electric shock, fire, and other
accidents.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

AC OUTPUT
The Lithium Cube’s inverter can operate most AC Appliances or a combination of appliances
up to 600 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 (25 ºC) will reduce the
Inverter’s ability 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.
• After ensuring that the main power is turned on, short press the AC output power switch
to turn on the AC output. Short press the AC output power switch again to turn it off.

EPS FUNCTION
EPS Authenticated by UL and UPS functionable.
This product supports the EPS (emergency backup power) function. You connect the power grid
and the AC input port of this product through the AC charging cable; Bypass mode (AC power
comes from the grid, not the battery); when the grid suddenly loses power, the product can
automatically switch to battery power supply mode within 10mS, at this time it is the inverter
mode (AC power comes from the battery, not the grid). This function does not support 0mS
switching. Please do not connect it to devices that require high uninterrupted power supply, such
as data servers and workstations, or use it after multiple tests to confirm whether it is compatible,
and it is recommended to use only one device during use, and do not use multiple devices at the
same time to avoid overload protection of the product. If the device does not operate normally
or data is lost due to failure to follow the instructions, our company will not bear the
correspending responsibility.

CONSTANT POWER
With the constant power output function, you can use the product to power appliances that
exceed the rated power of the device without disruption caused by overload protection. When
the power supply needs to drive high-power electrical appliances, the inverter will intelligently
regulate the output power of the power supply to maintain a constant actual output power,
ensuring that the electrical appliances can still operate reliably.
Enter/exit the constant power output function setting interface:
Short press the (2) LED light button and (3) DC output button at the same time to enter the setting
interface, and short press the (1) POWER button to cycle through the pages.
Page 0 can set the constant power mode On and OFF.
In this page, short press the (2) LED button to enter the modification state which is indicated by
the flashing power percentage icon . Short press the (1) POWER button to set the constant
power mode on or off in the modification state. Press the (2) LED light button again to save the
modified setting and exit the modification state.
In the setting interface, short press the (1) POWER button to Page 1 to set the Restore Factory
Setting, the default display is 0. Short press the (2) LED light button to enter the modification
state, which is indicated by the flashing power percentage icon. In the modification state, short

Please take note of the following when using the constant power output function:
1. The constant power output function is not enabled by default.
2. In the following cases, constant power output function is not enabled:
i. AC output is turned on in charging status (bypass mode).
ii. Constant power output function is turned off.
3. When using an appliance that exceeds rated power of the device, please connect only
one appliance. When connecting more than one electrical appliance, the change of
voltage may affect the usage of other electrical appliances.
4. Constant power output function is more suitable for heater and motor instead of all
electrical equipment. It is not suitable for some electrical appliances with voltage
protection (such as precision instruments). Constant power output function application is
subject to actual testing.
7. OPERATING TIMES
Below are typical products that can be operated by the Lithium Cube with estimated operating
times. The operating times will vary depending on the internal battery charge level, ambient
temperature and the actual AC or DC powered product being operated. The Lithium Cube will
not continuously operate AC appliances rated at more than 600 watts, such as air conditioners
or motors over 12 amps. 12V DC output is limited to 120W through the cigarette lighter or 5521
port connector. Operating times can be extended if charging cable is connected to the Lithium
Cube.
CONSTANT POWER
With the constant power output function, you can use the product to power appliances that
exceed the rated power of the device without disruption caused by overload protection. When
the power supply needs to drive high-power electrical appliances, the inverter will intelligently
regulate the output power of the power supply to maintain a constant actual output power,
ensuring that the electrical appliances can still operate reliably.
