The KUAIQU MPS-305QC Adjustable DC Power Supply is a professional DC power supply for mobile phone repair, specially designed for mobile repair technicians, smartphone motherboard repair engineers, and electronics maintenance professionals.
When repairing smartphones, precise voltage control and stable current output are essential to protect expensive motherboard components.
The MPS-305QC Wide Voltage DC Power Supply combines an adjustable DC power supply, USB fast charging tester, and smartphone repair tool into one compact workstation solution.
With real-time voltage/current monitoring, USB-A & USB-C charging analysis, OVP/OCP protection, output control, panel lock, and wireless charging test capability, it helps technicians quickly diagnose:
The clear 4-digit LED display provides real-time voltage and current monitoring, allowing repair technicians to accurately observe power consumption changes during smartphone troubleshooting, motherboard testing, and circuit diagnosis.

By locking the knobs and buttons, technicians can avoid unexpected voltage adjustments caused by accidental touches, providing safer operation during long-time debugging and motherboard repair.
The independent OUTPUT button allows users to turn the front output terminals ON/OFF without shutting down the entire power supply.
This provides faster and safer operation when connecting devices, changing test conditions, or performing repeated repair tests.
The built-in wireless charging area allows technicians to test wireless charging performance after smartphone repair.
Simply place a compatible phone on the top surface for quick charging verification without additional cables or equipment.
