Two small rectangular waterproof USB-C buck converter modules with green circuit boards and black components

Misskit

Misskit 2-Pack DC 12V/24V to 5V USB-C Buck Converter 5A 25W Waterproof Power Adapter

SKU CH-MJAG-H2PF8

Two waterproof buck converters step 12 V or 24 V input down to 5 V at 5 A for USB-C devices

  • Adapter typePower Converter
  • Converts 12 V or 24 V vehicle power to 5 V USB-C for phones and Pi boards
  • Delivers up to 5 A and 25 W for fast charging of tablets and single-board computers
  • 90 % conversion efficiency reduces heat and extends battery run-time
  • Built-in protection against reverse polarity, overload, over-current, overheat, low voltage and short circuit
  • Two waterproof modules included for redundant or dual-device installations

Two-pack buck converter for 12 V or 24 V systems

This twin-pack steps down 12 V or 24 V DC to a steady 5 V USB-C output rated at 5 A and 25 W. It suits Raspberry Pi 4 projects, phone charging or any 5 V device that draws up to the full rated current.

Simple wiring with built-in safeguards

Connect the input leads to an 8 V to 32 V source; reverse-polarity, over-current, over-temperature, low-voltage and short-circuit protection are integrated. The module accepts a wide range so a precise 12 V or 24 V rail is not mandatory, but the input must stay within the stated window.

High-efficiency sustained output

A switching regulator delivers around 90 % conversion efficiency, limiting heat during continuous 5 A loads. The waterproof housing helps in damp environments, yet prolonged maximum draw still requires adequate airflow to keep the internal temperature within safe limits.

Questions about this item

How can I confirm the converter is delivering 5 V at up to 5 A after wiring it?

Measure the USB-C output with a multimeter under load; it should read 5 V while supplying up to 5 A, and the built-in protections will shut down if limits are exceeded.

What comes in the package and what extra items are needed?

The pack contains two buck converter modules with USB-C output; you must supply a DC source between 8 V and 32 V and the USB-C cable for your device.

Should I use the 12 V or 24 V input setting for my Raspberry Pi 4?

Both 12 V and 24 V are within the recommended 8–32 V range; choose the voltage that matches your existing power supply.
