U.S.-based startup Evotrex has unveiled its PG5 recreational vehicle trailer, introducing a design that combines onboard energy storage, vehicle-to-vehicle (V2V) charging and active propulsion to support electric vehicles during towing.
The PG5 is equipped with what Evotrex calls its RangeBoost system, a bidirectional charging setup that allows the trailer to transfer energy to an electric tow vehicle while driving. The system monitors the tow vehicle’s battery state and supplies supplemental power from the trailer when needed, addressing one of the main challenges faced by EV owners — reduced driving range when towing.
The trailer integrates a 43 kilowatt-hour lithium iron phosphate battery pack with multiple energy sources, including a 1.5 kilowatt rooftop solar array, a fuel-optimised onboard generator and regenerative charging while in motion. Evotrex said the combined architecture can deliver more than 270 kilowatt-hours of usable energy per operating cycle, managed by an intelligent control system that balances charging, climate control and auxiliary loads.
In addition to supplying power, the PG5 features an electric propulsion assist system. A hitch-mounted force sensor detects towing load and applies torque from an onboard motor to reduce drag on the tow vehicle. The same system enables remote, low-speed maneuvering when the trailer is unhitched, allowing users to position it at campsites without a tow vehicle attached.
“Our goal with the PG5 was to design an RV that empowers adventurers to explore without compromise,” said Alex Xiao, chief executive and founder of Evotrex. “Its self-power generating capabilities and intelligent energy management system provide the comfort, reliability and control needed for confident off-grid travel.”
The trailer is fitted with digital monitoring and control tools through a dedicated tablet running the Evotrex application. The system provides real-time data on power usage, climate settings, water levels, tyre pressure and exterior camera views, as well as an off-grid planning calculator that estimates sustainable operating time based on weather and energy demand.
The PG5 rides on an automotive-grade air suspension with adjustable ride height and uses a reinforced dual-axle chassis designed for off-road conditions. Interior features include sleeping and dining areas, a full kitchen, a dry bathroom with shower and a motorised rear patio deck that can also function as a loading ramp.
Evotrex said pricing for the PG5 starts at $119,990 for the Pioneer version, with the higher-spec Atlas model priced at $159,990. The company expects production to begin in late 2026, with customer deliveries to follow.
