👨‍✈️ Can an APU really help with driver retention?

Absolutely. A well-rested driver is a happy—and loyal—driver.

Driver comfort is a top factor in retention. Our electric APUs provide a whisper-quiet and cool environment, allowing for deep, restorative sleep without the noise and vibration of a diesel APU or idling engine. Investing in our E-Series is a direct investment in your most valuable asset: your drivers.

📉 What are the biggest hidden costs of engine idling?

It's more than just fuel. It's accelerated engine wear, DPF issues, and lost time.

Engine idling costs you in four key ways:

Fuel Waste: Burning up to a gallon of diesel per hour.

Engine Wear: An hour of idling is equivalent to many miles of driving wear.

DPF Clogging: Leads to more frequent, costly, and time-consuming regens.

Downtime: Increased maintenance and repairs mean your truck isn't earning.

💡 I have an older truck. Is it too late to switch to an electric APU?

Not at all. Retrofitting an older truck is one of the fastest ways to modernize your fleet and slash operating costs.

Our systems are designed for easy installation on a wide range of new and older truck models. Upgrading your existing truck with our LiFePO₄ APU system is a smart, strategic move that immediately reduces your fuel bill and maintenance load.

🛡️ What kind of batteries do you use and are they safe?

We use the safest, most durable lithium technology on the market.

All our APU systems are powered by specially designed 12V Lithium Iron Phosphate (LiFePO₄) batteries. This technology is known for its exceptional safety and long life. Every battery pack includes a sophisticated Battery Management System (BMS) with built-in protections against:

Overcharging

Over-discharging

High temperatures

Low battery levels

⚖️ How much lighter is your system compared to a diesel APU?

Our electric APU system provides a significant weight reduction.

By removing the diesel engine, fuel tank, and exhaust system, our LiFePO₄-based APU is substantially lighter. This can translate to improved fuel efficiency for the main engine and a larger payload capacity for your truck.

🚛 What truck brands are your APUs compatible with?

Our APUs are designed for universal fitment across all major brands.

We have successfully installed our systems on Freightliner, Peterbilt, Kenworth, Volvo, Mack, International, and more. Our flexible mounting hardware and simple wiring make it adaptable to almost any Class 8 sleeper truck.

⚡ Does the installation require cutting into my truck's wiring harness?

No, our process is designed to be minimally invasive.

Our technicians integrate the system by making simple, clean connections to the truck’s electrical system, primarily at the alternator and battery terminals. We do not perform major modifications or cut into the factory wiring harness, ensuring the integrity of your truck's OEM systems.

💸 Are there any government rebates or incentives for installing an electric APU?

Yes, many states and federal programs offer grants or tax credits.

Programs promoting clean idle-reduction technologies are frequently available. We can provide you with information to help you search for current incentives in your area, which can significantly lower the initial cost and accelerate your ROI even further.

⛽ Besides fuel, what other savings can I expect?

The savings go far beyond the pump.

Reduced Engine Maintenance: Fewer hours on your main engine means longer intervals between expensive overhauls.

Extended DPF Life: Less idling means fewer forced regens and a longer lifespan for your Diesel Particulate Filter.

Zero APU Maintenance Costs: No oil, filters, or belts to replace on our electric APU.

No Idling Fines: Complete protection from costly compliance tickets.

📊 Do you provide a customized ROI calculation for my fleet?
