Built in the Real World. Proven Off the Grid.

IdleX isn’t a lab project or a whiteboard concept. It was built like the trucks it serves—tested under load, refined on the road, and engineered to work every single day.

The technology behind IdleX was first developed for government surveillance trailers operating in remote environments, where reliable, off-grid power was critical. Then it was refined in luxury RVs that demanded silent, long-lasting, no-compromise performance. Today, that same architecture powers IdleX: a solid-state electric APU built specifically for the demands of Class 8 sleeper cabs.

This is not a retrofit. It’s not cobbled-together components under a familiar logo. IdleX is built from the ground up using principles from the EV world—engineered around a proprietary solid-state battery system that outperforms lithium-ion in every meaningful category: safety, stability, thermal performance, and lifecycle.

The result is the first true alternative to diesel APUs:

Zero diesel.  Zero noise.  Zero fire risk.

And up to 40 hours of runtime—no matter the climate.

With IdleX, fleets save $10,000 to $12,000 per truck annually compared to running without an APU, and $6,000 to $8,000 versus diesel units—driven by reduced fuel consumption, fewer maintenance events, and significantly less engine wear. But the real value goes beyond the balance sheet. A more comfortable, quieter cab helps drivers get quality sleep, night after night—leading to improved alertness, lower fatigue-related incidents, and greater overall safety on the road. It also creates a more appealing work environment, increasing job satisfaction and giving fleets a competitive advantage in recruiting and retaining top drivers. Over five years, total per-truck savings can exceed $50,000—while delivering a smarter, safer, and more driver-centric solution built for the realities of long-haul operations.

This is what the future of idle elimination looks like.

Quiet. Clean. Proven.

Get ready. This changes everything.
