PlusRoc PR-4A061 USB-C Waterproof Adapter
The PlusRoc PR-4A061 is a DC-DC step-down module that converts an 8-35V input into a stable 5V output at up to 3A. It is built for Raspberry Pi 4, mobile phones and other 5V electronics that draw up to 15W. An IP68-rated enclosure protects the circuitry from water and dust in outdoor or vehicle installations.
Installation and Common Issues
The unit ships with 20 AWG power leads for direct wiring to a 12V or 24V source; no soldering is required if you use crimp connectors or terminal blocks. Polarity must be observed because reverse voltage will trigger the protection circuit and prevent operation. Mount the sealed body where airflow can dissipate heat when running near the 3A limit.
Limits of the 8-35V Input Range
The converter accepts DC inputs from 8V to 35V, with 12V and 24V systems recommended for best efficiency up to 96%. Operation below 8V or above 35V engages low-voltage or over-voltage protection and shuts the output down. The 15W ceiling means devices needing more than 3A at 5V cannot be powered from this adapter.

Questions about this item
How can I verify the PR-4A061 is delivering a stable 5 V at 3 A after wiring it up?
Measure the USB-C output with a multimeter or USB power meter while the load is connected; it should read 5 V and the adapter will maintain that voltage up to the 3 A limit.
What comes with the PR-4A061 and what must I source separately?
The unit includes the IP68 waterproof module with 20 AWG power leads and a USB-C output connector; you must supply the 8-35 V DC source and any device-side USB-C cable.
Which PlusRoc model should I choose if my project needs 15 W at 5 V with a USB-C plug?
Select the PR-4A061 — it provides 5 V at 3 A for 15 W through a USB-C connector, whereas the 5 A versions deliver 25 W and the USB-A variant uses a different output plug.
