  1. How much power consumption does each Deco take?

We can calculate the theoretical maximum power consumption based on the output voltage and current parameters of the power adapter. However, the actual power consumption should be lower than this value.

  1. Can I use a DC extension to extend the cable length of the original power adapter?

Normally, we don't recommend using an extension cable due to some possible risks.

1. The quality of the extension cable is uncontrollable, if the contact resistance of the interface is too large, it will cause the interface to heat up and cause safety hazards.

2. The increase in cable loss will increase the output power of the power adapter, resulting in a decrease in the life of the power adapter. If the rated power of the power adapter is exceeded, safety hazards will occur.

If the customer insists on an extension cable, we can provide the parameters of the power cord. However, any problems caused by the extension connection will violate our warranty.

The parameter of the power interface (Male Size)

inner diameter: 2.1mm

outer diameter: 5.5mm

copper column length: 9.0mm
