Commercial EV manufacturer Harbinger Motors is branching out into a new line of business. The new Harbinger Industria division will offer Harbinger battery technology as standalone products for energy storage and auxiliary power.
Airstream, the iconic manufacturer of handcrafted, riveted aluminum travel trailers, is the first customer to integrate Harbinger’s energy storage technology. Airstream recently unveiled its new Trade Wind 27FB travel trailer, which features the Harbinger Power System to support off-grid camping, air conditioning and integration with solar power.
Other EV startups have been dropping like fruit flies, but Harbinger’s sales grew steadily throughout 2025, and the end of the IRA tax credits didn’t even amount to a speed bump. In a recent in-depth interview, co-founder and CEO John Harris told Charged that the company’s secret sauce includes a deep bench of tech talent, vertical integration, and a narrow focus on vehicle classes in which the company can offer price parity with legacy ICE trucks.
Harbinger designs and manufactures its proprietary high-voltage battery system at its factory in California. The company says its vertically integrated approach enhances performance, durability and cost efficiency. Harbinger’s batteries feature lithium-ion cells from Panasonic Energy, and are built to automotive-grade standards.
Features of the Trade Wind 27FB next‑generation energy system include:
- The largest battery capacity in the Airstream travel trailer lineup: up to 18.5 kWh.
- A fully integrated 600 W rooftop solar power system.
- A 50-amp service with dual air conditioners equipped with heat pumps.
- A 5,000 W inverter to enable a fully inverted electrical system.
The Harbinger Power System continuously monitors system health and ambient conditions, automatically managing battery performance to maintain optimal operation. Intelligent control of high- and low-voltage states helps prevent depletion, while a liquid-based thermal system protects the battery from extreme temperatures to extend service life. A custom display provides real-time visibility into system health, energy use and power availability across batteries, shore power and solar.
“Harbinger is excited to be driving the reindustrialization of American supply chains, bringing our industry-leading battery technology to market with Airstream, the most iconic brand in recreation,” said John Harris. “By introducing automotive battery systems to the RV market, we’re helping set a new standard for off-grid performance, and demonstrating that high-quality, American-made battery systems can be delivered at a price point that makes sense for customers.”
“The Airstream Trade Wind 27FB has the most capable off-grid electrical system we’ve ever offered in our travel trailer product line,” said Airstream President and CEO Bob Wheeler. “By integrating Harbinger’s industry-leading battery technology in our travel trailers, our customers can stay off-grid longer with confidence.”
