Tesla export tool announced
RoamEnergy unveiled a PowerBridge Pro device that enables certain Tesla models to export power back to a home at rates up to 7.5 kW. The product is a niche capability and not a universal home backup standard, but it highlights growing product-level options for EV‑to‑home use. (evchargingstations.com)
Electric vehicles usually take power from the grid. RoamEnergy’s new PowerBridge Pro goes the other way for some Teslas, sending battery power out at up to 7.5 kilowatts. (evchargingstations.com) RoamEnergy said the device is its second-generation Tesla export tool, after a 3.5-kilowatt product introduced in October 2025. The new unit adds a 240-volt NEMA 14-50 outlet and raises output to 32 amps, or 7.5 kilowatts. (evchargingstations.com, evchargingstations.com) The company is selling the product through Kickstarter and said the first batch is scheduled to ship in August 2026. Coverage of the launch said the device is aimed at outages, job sites and off-grid use, not just emergency backup. (kickstarter.com, evshift.com) The basic idea is simple: the box works like an inverter, turning the car’s direct-current battery power into the alternating current used by household appliances. RoamEnergy’s launch materials describe it as vehicle-to-load, meaning it can run equipment directly, with possible vehicle-to-home use in the right setup. (evshift.com, kickstarter.com) Compatibility is limited. Reports on the launch said the device works only with Tesla vehicles that support the Combined Charging System protocol, generally 2021 or newer models unless an older car has been retrofitted. (evshift.com) That makes it different from Tesla’s own Powershare system, which is built around Cybertruck and fixed home hardware. Tesla says Cybertruck Powershare Home Backup can provide up to 11.5 kilowatts to a house and start supplying power within one minute of an outage. (tesla.com) Ford already offers a similar factory-backed setup on the F-150 Lightning. Ford says the truck’s Pro Power Onboard system is available at up to 9.6 kilowatts, and Sunrun says the Lightning’s home integration system can deliver 9.6 kilowatts during an outage. (ford.com, sunrun.com) RoamEnergy’s pitch is narrower than those built-in systems: use an existing Tesla battery as a portable power source without waiting for Tesla to add full bidirectional backup across its lineup. The launch coverage also said the device is not yet safety-certified, and the company said certification would come when the product reaches market. (evshift.com) The result is not a new standard for every electric vehicle owner. It is one more sign that car batteries are being treated less like fuel tanks and more like mobile backup systems.
