Q&A
Do you provide support for shipping and customs clearance?
Yes, we offer international logistics solutions including export documentation and customs advice.
Will reversing the positive and negative poles damage the device when connecting the battery?
The device has a built-in reverse connection protection function, which will automatically cut off the circuit when the positive and negative poles are reversed to avoid damage caused by reverse current inflow; just adjust the connection order of the positive and negative poles of the battery clip and re-power on to use normally.
Does it support inductive loads?
Modified sine wave inverters are suitable for resistive loads; for inductive loads, pure sine wave models are recommended.
Can it be connected to a battery long-term?
Yes, ensure good ventilation to avoid overheating.
