PD65W DC-to-USB-C module for 5.5 × 2.5 mm inputs
This step-down module accepts 8 to 30 V DC through a 5.5 mm outer, 2.5 mm inner barrel connector and delivers up to 65 W over USB-C. It supports PD3.1 PPS and QC3.0 profiles at 5 V 3 A, 9 V 3 A, 12 V 3 A and 20 V 3.25 A. The board is aimed at engineers and hobbyists who need adjustable fast charging from a DC source.
Check barrel size and input voltage before ordering
Verify that your power supply uses a 5.5 mm × 2.5 mm plug; the 5521 variant with a 2.1 mm inner pin will not fit. Ensure the source voltage exceeds the desired output — for 20 V fast charging the input must be above 20 V. The module only steps down, so an input below the target voltage cannot work.
Sustained 65 W output with 92 to 97 % efficiency
Conversion efficiency stays between 92 and 97 percent under load, and output ripple is rated at 200 mV. Built-in protections cover input over-voltage, under-voltage and over-current, plus output over-current, short-circuit and overall over-temperature shutdown. No-load current remains below 3 mA, so the board runs cool during continuous operation.

Questions about this item
Does the pack contain three modules or just one, and is a DC power supply included?
The listing includes one PD65W fast-charging module with a 5.5×2.5 mm DC jack; a separate 8–30 V DC power supply must be provided by the buyer.
Should I choose the 5521 or 5525 version for a 5.5 mm outer diameter and 2.5 mm inner diameter jack?
Select the 5525 model, which matches a 5.5 mm outer and 2.5 mm inner diameter barrel connector; the 5521 variant uses a 2.1 mm inner pin.
If I feed the module 24 V from a laptop brick, will it deliver the full 65 W at 20 V 3.25 A to my phone?
Yes, with a 24 V input the module can output 20 V at 3.25 A for 65 W; power the brick on before connecting the module so the handshake completes correctly.
