① USB is only for charging , do not have date exchange function;
② Before charging please check carefully if the charging current of the appliance is
under the inverters current, if it is exceed the charging current of the inverter please
do not use, or it may destroy the USB port.
③ Some appliance must charging use certain charger, please don’t charge with USB
port.
2. Please check the voltage carefully before use:
Inverter’s input voltage must be same as battery’s voltage; appliance’s working voltage
must be same as inverter’s output voltage; once all are same, connect them in right way
based on “Connection Explanation” of the manual.
3. Please use the inverter in ventilate condition and make sure the fan is not blocked.
e. Do not put the inverter under rain or in humid place, keep it dry. In order to keep a
long lifespan of the inverter, please keep it work under 85% of the related power.
4. The inverter have input under voltage protect function, input over voltage protect
function, over load protection function, over temperature protect function and short
circuit protect function. If these happened, the inverter will stop work and after the
breakdown, the inverter will restart work automatically.
5. To save energy, the fan will not work unless the under two situations:
① The fan will work when the load is exceed 30% of the related power of the
inverter;
② When the inside temperature of the inverter exceed 60 degree, fan work.
6. About extended cable using:
① We do not recommend use extended cable between the inverter and the battery,
because it will case lost of DC electricity and affect the effect of the inverter.
② If really need use extended we suggest you use high quality cable to reduce the loss
of electricity.
7. Other matters：
① This is modified pure sine wave inverter; When measuring the voltage please use
precise equipment. (RMS)
② When supper power to audio system, radio or TV, the appliance may have
interference and this is normal phenomenon;
③ W hen usi ng i n cars, pl ease stop use the i nverter w hi l e the engi ne stopped；
④ Pl ease do not open the i nverter, i f need m endi ng pl ease ask professional to mend
it.
- Security matters:
1. Please do not operate the inverter while your hand is wet, Keep it from the touch of
children.
2. The temperature of the shell will be high after longtime working, so do not touch it in case
scalded;
3. Do not put metal into the inverter in case not to electric shock.
