22.5W 5-Port Fast Charging Module – QC4+PD3.0 Bidirectional Support

The 22.5W 5-Port Fast Charging Module – QC4+PD3.0 Bidirectional Support works through protocol negotiation – the charger and the device communicate to agree on a voltage and current level that the device can safely accept. The Fast Charging Module handles that negotiation through QC4+ on the USB Type-A port and PD3.0 on the USB Type-C port, covering the fast charging standards used by most current Android phones, iPhones, and USB-C laptops. Total output capacity sits at 22.5W, which the module distributes across active ports rather than delivering the full 22.5W independently on each port simultaneously.

The bidirectional operation separates this 22.5W 5-Port Fast Charging Module from single-direction charger boards. One path charges the internal battery from an input source while a second path delivers regulated output to connected devices – both running concurrently without requiring a manual switch. This pass-through charging behaviour means the power bank continues supplying output while its own battery replenishes from a wall adapter.

The Type-C Power module embedded circuit board format suits DIY power bank builds where the charger integrates inside a custom enclosure, replacing discrete voltage regulation and protocol negotiation circuits. Total 22.5W output is shared across all active ports. Connecting five devices simultaneously splits that budget, reducing per-device charge speed. For single-device maximum-speed charging, only one port should carry the load. The 22.5W fast charging module available on StemVolt, for building multi-port chargers and high-specification portable power bank.
