Q&A
How long does it take to become an authorized distributor?
The process typically takes 2-4 weeks, depending on the discussion and agreement finalization.
Can I order samples before production?
Yes, we offer sample evaluation and prototype testing.
What is the difference between labeled 6000W and full power 3000W?
Labeled 6000W is peak power, which is only used to cope with the instantaneous high-power demand during device startup (such as air conditioner, motor startup); full power 3000W is continuous power, referring to the power that the device can stably output for a long time. When driving appliances daily, 3000W should be used as a reference to avoid total power overload.
Is customization available?
OEM/ODM support for logo, color, and packaging design.
