The trailer that
pulls its weight.

Electrify your crews without rebuilding your yard. One trailer charges tools and equipment, on the road and at the job site, and covers its own weight behind the truck.

The problem

A trailer shouldn't
be dead weight.

If your business tows, you know the bill. Work trailers haul the crew's whole day and give nothing back.

Generator overhead

Fuel runs, exhaust, and noise complaints. And the crew still runs out of gas by Thursday.

The towing burden

Gas or electric, the truck pays for every pound it drags. A dead trailer costs fuel and miles you planned on keeping.

The visibility gap

No charge state, no location, no service records. The trailer is the one asset nobody can see.

The fix

Same crew. Same route.
Different trailer.

Swap the trailer and the same day runs cleaner: power on site, a lighter tow, and a fleet you can finally account for.

Clean power at the job site

240/120 V outlets and tool charging at the tailgate. Quiet, exhaust-free, and ready before the site has power.

It covers its own weight

An onboard e-axle offsets the trailer's own drag and rolling resistance, so the miles you planned on stay with the truck.

A trailer you can finally see

Charge state, location, and service history for every unit, live in the fleet app and inspection-ready.

Under the deck

How it works.

Five modules, one platform: the hardware that turns a trailer into the crew's power supply.

Elementrailer battery pack module with high-voltage connectors

Large battery pack

10–60 kWh of modular storage mounted low on the deck: the energy source for tools, equipment, and the trailer itself.

E-axle

A motorized axle that offsets the trailer's own drag and rolling resistance, so it covers its own weight behind the truck.

Loaded trailer on a downhill grade with energy flowing from the wheels back to the battery under braking

Regenerative braking

Downhills and stops feed energy back into the pack, and braking stays smooth at full load.

Trailer control module receiving an over-the-air update from the cloud, with progress shown on a laptop and phone

Telematics & OTA

Charge state, location, and health stream live to the fleet app, and updates ship over the air.

Safety by design

The chassis is engineered from the ground up around the battery: mounted low, centered, and weight-balanced. We build as NATM members.
