How much power does the Charging Module require?Updated a month ago

The SP Connect Charging Module requires a power supply of at least 5 V / 2 A (minimum 10 W) for reliable operation.

Minimum requirements

For regular operation of the Charging Module, the power source should provide at least:

  • 5 V / 2 A
  • 10 W total power

If the power source does not meet these requirements, charging performance may be reduced or charging may be interrupted.

Requirements for fast charging

For wireless charging at 7.5 W or 10 W, the power source should support at least:

  • 9 V / 1.67 A
  • 15 W total power

The actual charging power also depends on the smartphone being used and the charging protocols it supports.

For the best possible charging performance, we recommend using a power source that supports:

  • Quick Charge (QC 2.0 / 3.0 / 4.0)
  • USB-C Power Delivery (PD)

These standards provide the required voltage and current for optimal charging performance of the Charging Module.

Summary

The Charging Module requires at least 5 V / 2 A (10 W) for reliable operation. For fast charging, we recommend a power source with at least 15 W and support for Quick Charge or USB-C Power Delivery.
