How long does it take to become an authorized distributor?
The process typically takes 2-4 weeks, depending on the discussion and agreement finalization.
What happens if the positive and negative poles are reversed when connecting the battery?
The device features built-in reverse polarity protection. If the positive and negative terminals are connected incorrectly, the circuit will automatically disconnect to prevent damage to the equipment. Simply adjust the battery clip connections (red clip to positive terminal, black clip to negative terminal), then restore power to resume normal operation.
What’s the main difference between your OEM and ODM services?
OEM uses your brand on our standard products; ODM creates entirely new products based on your concept or specification.
Can 4 USB ports fast charge at the same time?
Yes, 4 USB ports can fast charge mobile phones, tablets and other devices at the same time, meeting the needs of simultaneous charging of multiple devices.
