The Evotrex-PG5 is built around a 75 kW gas-powered generator and 43 kWh LFP battery, a power system you won't find in any competing trailer at any price. Here's how it stacks up against the most popular alternatives in a similar size range.
Onboard Battery
LFP chemistry. Up to 20× more usable storage than a typical trailer.
Integrated Generator
Gasoline-powered. Built into the platform from day one, not an add-on.
On-Demand Energy
Combined: 43 kWh battery + generator (20 gal) + rooftop solar.
