Optimal Tips for Using Car Power Inverter
- Please use our standard battery cable as much as possible, otherwise the car power inverter will not be able to output enough power.
- Please turn on the inverter before starting the load. Meanwhile, please disconnect the load before turning off the inverter.
- It is forbidden to connect the mains to the output port of car inverter. It is also not allowed to reversely connect the battery to the inverter on load.
- Do not power the household appliances under the overload. For example, when using the car inverter for powering motors, pumps, air conditioners and other inductive loads, please ensure that the value of at least 3 times rated power of the load must not exceed the rated power of power inverter.
- When the red indicator of the inverter lights with buzzing, please check if it is overloaded and the battery is fully charged (Whether your battery is new or not, please charge the battery for at least 3 hours before trying again).
- Please turn off the power inverter when not using it.
- When the car inverter beeps, please make sure to first disconnect the load, turn off the inverter, and then check what the problem is.
