SKU CH-R8AZ-0D2Q1

A five-pack of 2.0 mm pitch 4-pin to USB-C female adapters delivering 5 V 3 A power with waterproof dustproof rubber plugs for DIY electronics and small appliances

  • 5-pack value set for multiple DIY power conversion projects
  • 0mm pitch 4-pin interface ensures stable power input connection
  • DC 5V 3A output delivers safe reliable charging for USB-C devices
  • Waterproof dustproof rubber plug protects port from moisture and debris
  • Plug-and-play conversion turns 4-pin source into universal USB-C female charging port

Five-pack power conversion kit

This SMUGDESK adapter set contains five identical units that convert a 2.0mm pitch four-pin power source into a USB-C female port. Each unit delivers a DC 5V 3A output suitable for charging compatible devices. The multipack format supports projects that require several conversion points at once.

Waterproof rubber plug protection

Every adapter includes a fitted rubber plug that covers the USB-C port when not in use. The plug seals the opening against moisture, dust and debris to maintain reliable contact over time. This protection is useful in workshop or outdoor environments where the port may be exposed.

DIY electronics and small-appliance builds

The adapters suit makers who need to add USB-C charging to custom power modules, prototype boards or low-power appliances. They are not intended for high-current applications beyond the rated 3A output, nor for data-transfer roles. Buyers needing a different pitch connector or higher amperage should look at alternative conversion solutions.

Questions about this item

Will the waterproof dustproof rubber plug need replacement after repeated use?

The rubber plug protects the USB-C port from moisture and debris, and can be removed or reseated whenever the adapter is connected or disconnected.

What limits continuous operation at the rated 3 A output?

The adapter is specified for DC 5 V 3 A; sustained loads at that current will be constrained by the 4-pin power source and cable resistance.

How much heat does the adapter generate when powering a device all day?

The conversion cable passes 5 V 3 A through the 2.0 mm pitch 4-pin connector to the USB-C port; heat will depend on the load and the source supply.
