Victron Interface MK3-USB-C - VE.Bus to USB-C Adapter

The Victron Interface MK3-USB-C - VE.Bus to USB-C Adapter is the bridge between your marine power system and modern device management. Whether you're monitoring battery health on a long offshore passage, managing solar inputs from your boat's charging array, or troubleshooting electrical systems at anchor, this adapter connects your Victron VE.Bus network to any laptop, tablet, or smartphone with USB-C capability. For anglers and boaters who depend on reliable power systems—especially those running advanced battery monitors, inverters, and multi-stage chargers—this interface transforms complex diagnostics from mystery into actionable intelligence.

The adapter implements the industry-standard VE.Bus communication protocol, allowing real-time data streaming and device configuration without breaking the circuit or adding complexity. Its compact form factor (4 x 2 x 5 inches, weighing just 0.25 lbs) fits easily into a nav station or tackle locker, and the USB-C connector is fully reversible—no more fumbling with orientation in rough seas. The MK3-USB-C functions as a bidirectional gateway, meaning you can not only monitor system parameters like state-of-charge, voltage, and current draw, but also adjust settings and firmware updates remotely. Built to Victron's marine-grade standards, it handles the salt air, vibration, and electrical noise that characterize life on the water.

This interface is essential for anyone operating multi-battery systems, hybrid power setups, or Victron's comprehensive energy ecosystem aboard. Cruising anglers managing extended time away from shore power, commercial fishing operations monitoring expensive battery banks, and recreational boaters troubleshooting charging issues all benefit from direct system access. Installation is straightforward: connect one end to your VE.Bus network (daisy-chain compatible with other Victron components) and the USB-C end to your device, then launch the VictronConnect app for full system visibility. Compatible with all Victron MultiPlus, Quattro, Phoenix, and Color Control devices that feature VE.Bus networking, the adapter pays for itself the first time it prevents a dead battery or identifies a parasitic drain.
