Waterproof USB-C step-down adapter

This waterproof DC-DC converter steps 12 V or 24 V vehicle power down to a regulated 5 V output through a USB-C connector. It accepts an input range of 8 to 32 V and can deliver up to 3 A with a claimed peak efficiency of 96 %. Built-in overload, over-current, overheat and low-voltage protection helps keep connected devices safe.

Ideal for Raspberry Pi 4 and phone charging in cars

Makers powering a Raspberry Pi 4 from a vehicle electrical system will appreciate the stable 5 V rail and USB-C plug. Drivers who want a compact, rugged way to charge phones or similar 5 V gear from a 12 V or 24 V supply also fit the target use case. Buyers needing more than 3 A, adjustable voltage, or a bare-board module without the waterproof housing should look at something else.

Check your wiring and device draw before ordering

Verify that your source voltage stays within the 8 to 32 V window and that the load does not exceed 3 A. The supplied leads use 20 AWG wire, so confirm the gauge is adequate for your installation length and current. Ensure the USB-C port matches the charging or power input specification of the device you intend to connect.

Questions about this item

What input voltage source do I need to run this 12V/24V step-down adapter?

Connect it to any DC source between 8 V and 32 V — a 12 V or 24 V vehicle battery is typical — and the module will deliver a steady 5 V output.

Will this converter work if I keep my existing 12 V accessories on the same circuit?

Yes, the adapter draws only what it needs up to 3 A at 5 V and includes overload, over-current, overheat and low-voltage protection so it won’t disrupt other 12 V loads.

How can I confirm the USB-C port is delivering the full 3 A at 5 V after wiring it up?

Measure the output with a multimeter under load; you should read 5 V and the connected device (for example a Raspberry Pi 4) should boot and run stably at its rated current.
