Ruth's sister

Ruth's sister 5V 3 USB Port 40W Internal Power Cable B2RD4NB105408

SKU CH-Z2A1-AGQTR

A 5 V internal power cable with three USB ports delivers up to 40 W from an 8–24 V source at over 85 % efficiency

  • Charges three devices simultaneously via three USB ports
  • Delivers up to 40 W total output power
  • Accepts 8–24 V input for flexible installations
  • 1 m (3.3 ft) cable reaches internal drive bays
  • Over 85 % conversion efficiency reduces heat

Internal 5V USB power cable

The Ruth's sister B2RD4NB105408 converts an 8-24V internal supply into a regulated 5V output with three USB ports. It delivers up to 40W total power for charging phones, tablets or other USB devices inside a build. The one-metre cable provides flexible routing within a chassis. Conversion efficiency exceeds 85 percent.

Tool-free clip mounting

A built-in clip secures the module to a chassis rail or drive cage without screws. The 3.3-foot cable reaches most internal USB headers or device bays. Ensure the source voltage stays within the 8-24V range; exceeding it can damage the converter. No intelligent charge negotiation is supported, so devices fall back to standard 5V charging.

Three ports share 40W

The three USB outputs share the 40W budget, so simultaneous fast charging of multiple tablets may hit the limit. Phones and low-draw accessories run comfortably within the headroom. The synchronous voltage-stabilisation design keeps heat low during sustained loads. The unit is not a display-equipped smart charger and does not support proprietary fast-charge protocols.

Questions about this item

How do I verify the 40W converter is working after connecting it to an 8-24V source?

Connect the 1m cable to an 8-24V input, then plug up to three devices into the USB ports; all should charge simultaneously with the converter staying cool thanks to its high-efficiency synchronous voltage stabilization technology.

What is included in the box and what must I buy separately?

The package includes one converter with a 1m cable and three USB ports; you must supply your own 8-24V power source and the USB charging cables for your phone or tablet.

Which version should I choose for charging multiple devices at once?

The single B2RD4NB105408 model delivers 40W across three USB ports with over 85% conversion efficiency, making it the only version needed to charge three devices simultaneously from an 8-24V supply.
