You Can Power Your Whole Home With Your Tesla Battery Using The Roam PowerBridge Pro

Why It Matters

The PowerBridge Pro turns a Tesla into a mobile power source, expanding off‑grid capabilities for owners and signaling a shift toward third‑party vehicle‑to‑home solutions.

Key Takeaways

• Rome Energy PowerBridge Pro delivers up to 7.5 kW 240 V output.
• Device tricks Tesla into DC fast‑charging mode to export power.
• Supports both 120 V (3.5 kW) and 240 V (7.5 kW) outlets.
• Requires manual Tesla charge‑port opening; safety features include over‑current shutdown.
• Pre‑order price $1,599 with $900 discount; limited availability.

Summary

The video introduces Rome Energy’s second‑generation PowerBridge Pro, a portable inverter that lets Tesla owners draw electricity from their vehicle’s battery to run household appliances. By mimicking a DC fast‑charging session, the unit convinces the car to export power, offering up to 3.5 kW on 120 V circuits and a full 7.5 kW on 240 V NEMA 14‑50 outlets. Key specifications include dual 20‑amp NEMA 5‑20 receptacles, a 32‑amp 240 V plug, a built‑in battery for startup, USB‑C ports for charging and firmware updates, and a mobile app that displays real‑time voltage, current, and low‑battery cut‑off settings. Compatibility is limited to Tesla models with CCS ports (2021 onward or retrofitted older cars), and the device is not water‑resistant nor safety‑certified beyond a one‑year warranty. During the demo, the reviewer powers a 1,500‑watt heater and a 1,800‑watt convection oven simultaneously, pushing the 120 V limit to 3.5 kW. He also notes the two‑step activation sequence to prevent accidental drain and the need to manually open the Tesla charge port, a design choice confirmed by the manufacturer. The unit’s internal battery can be recharged from a standard wall outlet, addressing a flaw in the first‑generation model. If widely adopted, the PowerBridge Pro could give Tesla owners a practical, albeit limited, vehicle‑to‑home (V2H) solution for camping, tailgating, or emergency backup power, while highlighting the growing market for third‑party V2G hardware that operates outside OEM warranties.
