Multiquip 42780 Accessory Port USB Power

The Multiquip 42780 Accessory Port USB Power is a genuine OEM component designed for Whiteman and PRX series ride-on power trowels, including STXDF, HTX6H, STX6H, PRX, and HTXG6DF models. As a direct Multiquip OEM part, the 42780 is built to the exact specifications of the original unit installed at the factory, ensuring a correct, hassle-free installation. Whether you are restoring a damaged port or completing a machine refresh, this part ships as a verified Multiquip replacement to keep your operator console fully functional.

Key Features

• Genuine OEM Electrical Specification — Manufactured to the original voltage and connector spec, ensuring the port delivers consistent USB charging output without risk of under-powering connected devices.
• Direct Console Fit — Engineered to match the original mounting configuration on Whiteman ride-on trowel operator consoles, connecting directly to the existing wiring harness without splicing or adapter modifications.
• Broad Ride-On Trowel Compatibility — Confirmed fitment across STXDF, HTX6H, STX6H, PRX, and HTXG6DF models, covering both hydrostatic and hybrid ride-on power trowel families.
• Keeps Operator Devices Powered On the Deck — A functioning USB port allows operators to charge phones, GPS units, and other site devices directly from the machine, maintaining productivity during long finishing runs.
• Electrical Integrity Matters — A failed or damaged accessory port can introduce unwanted resistance into the console circuit; replacing it with the correct OEM part protects the surrounding wiring harness from overcurrent stress.

The Accessory Port USB Power provides an onboard 12V-to-USB power outlet integrated into the ride-on trowel's operator console, allowing the machine operator to charge or power USB devices directly from the equipment. This is particularly useful during extended concrete finishing operations where keeping a device charged on the deck avoids unnecessary interruptions. When the port fails — whether from physical damage, moisture ingress, or connector wear — the USB output is lost entirely, and leaving a damaged port in place risks drawing irregular current from the console's electrical circuit.
