WARNINGS AND CAUTIONS
WARNING
•When the product is in use, please ensure that children are kept away from the
product. The inverter works with the same AC power as the mains, please pay
attention to the safety of electricity!
•When this product is loaded with high-power appliances, the product shell will be
hot. When using, please pay attention to the high temperature source.
•please do not use this product in flammable and explosive environment.
•the risk of electric shock: when the appliance is inserted into the AC outlet, please
ensure that your fingers do not touch the metal piece of the outlet and ensure
safe insertion.
CAUTIONS
•When the inverter AG socket is working, do not use electrical appliances that are
already charged to plug in, this will damage the product.
•Please do not cover the inverter shell, keep ventilation to avoid affecting the heat
dissipation.

Connection Instructions
Connect the clip cable to the 12V DC battery, check the battery type and battery voltage
match before connecting the battery.
CAUTIONS: DANGER OF REVERSE CONNECTION
•When connecting the red and black clip wire, make sure that the red is connected
to the positive terminal of the battery and the black is connected to the negative
terminal of the battery to avoid blowing the fuse by reversing the connection.
•make sure that the input cable is connected to a 12V battery, 6V batteries are not
allowed.
•connect the load that needs to be run to the AC socket or USB port, see
"Operation Guide" for details.
•Press and hold the switch for 1 second to start the inverter power.
•When the inverter is not in use, please disconnect the clip cable from both ends
of the battery to avoid static loss of battery power.

Operation Guide
•After long press the switch for 1 second, the socket outputs 220VAC, connect the
load to be run to AC output socket or USB port.
•If the load power exceeds the rated power, the overload protection will start and
the product will shut down automatically. Please reduce the load and connect a
load with lass than the rated power after the product restarts.
•When the battery voltage drops to 10V, the under-voltage protection function will
start and the product will automatically shut down. This can prevent the battery
from being damaged and ensure that the battery needs enough power when the
car starts.
•If the working temperature of the product exceeds the safe operating
temperature due to poor ventilation or high external temperature, the
overtemperature protection function will be activated and the product will be
automatically shut down, and it will automatically resume working when it
returns to normal temperature.
•If a defective battery charging system causes the battery voltage to rise to a
dangerous level greater than 18.5V, the overvoltage protection function will start
and the product will be automatically shut down.
CAUTION
Although this product is equipped with overvoltage protection, it may still damage the
product if the input voltage exceeds 17V.

Troubleshooting
PROBLEM: NO OUTPUT AND ABNORMAL POWER DISPLAY LIGHT
Possible Causes
Measures
Battery defects
Check the battery and replace it if
necessary
Loose battery clips
Check the connections
PROBLEM: OUTPUT VOLTAGE IS TOO LOW
Possible Causes
Measures
A standard average AC voltmeter
measuring the output voltage will result
in a measurement that is off by 5 to 15 V
Inverter output “pure sine wave”,
requiring measurement with a voltmeter
marked “true RMS” or with a voltmeter or
oscilloscope capable of measuring RMS
Battery voltage is too low
Charging the battery
PROBLEM: PRODUCT DOES NOT WORK
Possible Causes
Measures
Load power exceeds the continuous
output power of the product, overload
protection starts shutdown
Please use a load no greater than the
rated one
The load power is lower than the rated
power of the product, capacitive load or
inductive load too high power-on surge
caused by overload protection shutdown
The start-up surge of the load exceeds
the starting capacity of this product,
please choose a suitable 220V power
supply
The product is overheated by poor
ventilation to start the over-temperature
protection shutdown
Unplug the inverter from the output
socket, cool it for 15 minutes and remove
the shade.
Move the product to a cooler location. If
continuous operation is necessary,
reduce the load and restart
