c. Scope of electric appliance that are incompatible with the USB
(Only for inverters with USB port)
USB is only for charging, and does not support data exchange function;
Before charging please check carefully if the charging current of the
appliance is below the inverters current. If it is exceeds the charging current of
the inverter please do not use, or it may destroy the USB port.
Some appliances must be charged using a specific charger, so please don’t
charge with the inverters USB port.
4. Please use the inverter in ventilated areas and make sure the fan is not
blocked. Do operate the inverter in rain or in humid places, keep it dry.
In order to have a long lifespan of the inverter, please keep it working under
85% of the related power.
5. The inverter has input under voltage protection, input over voltage protection,
overload protection, over temperature protection and output short circuit
protection. If these conditions occur, the inverter will stop working and after a
short period where it has cooled down the inverter will restart working
automatically.
6. To save energy, the fan will not work unless:
a. The fan will work when the load exceeds 30% of the related power of the
inverter;
b. When the inside temperature of the inverter exceed 60 degree the fan will
work.
7. Extension cable use:
a. We do not recommend the use of any extension cables between the inverter
and the battery, as it will cause lost of DC electricity and effect of the inverters
output voltage.
b. If really need use extended we suggest you use high quality cable to reduce
the loss of electricity.
8. Other matters
：
a. This is modified sine wave inverter; when measuring the voltage please use
precise equipment. (RMS)
b. When supplying power to an audio system, radio or TV, the appliance may
have interference and this is normal.
c. When using in cars, please don’t use the inverter while the engine has
stopped.
d. Please do not open the inverter, for servicing please use a professional.
Safety:
1. Please do not operate the inverter while your hands are wet. Keep it away
from children.
2. The temperature of the shell will be high after extended use; so do not touch
