Product
About the Cabin Comfort.
What exactly is the Cabin Comfort?
The Cabin Comfort is a self-contained climate control unit built specifically for long-haul sleeper cabs. It heats and cools the cab using its own battery pack, so the truck’s diesel engine can stay off all night — no fuel burning, no engine noise, no fumes.
What versions are available?
Two installation options: under the sleeping berth (Cabin Comfort, on request) or external installation (external mount). Same performance — pick the form factor that fits your truck.
How much does it weigh?
131 lb. Light enough that two people can move it during install — no special lifting equipment required.
Does the Cabin Comfort heat and cool?
Yes. The same unit handles both heating in winter and cooling in summer, so drivers stay comfortable year-round without the engine running.
Is there a remote monitoring app?
Yes. A proprietary app gives fleet managers and drivers real-time visibility into status and performance.
Installation
Getting it on the truck.
How long does install take?
About 2 hours. The website also states 3 hours as a conservative figure — either way, no full-day shop visit.
Do I need a mechanic?
No mechanical skills required. The unit is plug-and-play with only two cables.
Which cables connect to the truck?
Only two umbilical cords: a 12 V cable to the existing battery pack and a control cable to the on/off power switch. No alternator tap. No engine connection.
Does it work on my truck?
The Cabin Comfort is engineered for Class 8 sleeper cabs with standard 12 V electrical systems. Contact us with your make/model and we’ll confirm fit.
Where does it physically mount?
Under the sleeping berth (Cabin Comfort) or externally (external mount). Both versions hide the hardware away from the driver and keep the cab clutter-free.
Savings
Show me the money.
How much diesel will I save?
About 1 gallon per hour when the truck is not in motion — up to 12 gallons a day for long-idle drivers. Annual: roughly 2,921 gallons per truck.
What does that translate to in dollars?
Average monthly savings of $750 - $1,000 per truck in diesel alone. Maintenance and depreciation savings stack on top.
Does the engine wear less too?
Yes. Every idle hour adds invisible “idling miles” that wear pistons and cylinders. Less idling = longer oil intervals, fewer DPF cleanings, less air-filter wear and better resale value.
When do I break even?
Short-term financial breakeven. The diesel savings often pay for the Cabin Comfort in months, not years. Run the savings calculator for your exact payback.
Where does the calculator data come from?
Argonne National Laboratory and the US Department of Energy. We use 0.98 gph as the new-truck average; empty trucks idle at 0.64 gph and loaded ones at 1.38 gph.
Compliance
Staying legal everywhere.
Does the Cabin Comfort help with California’s 5-minute idle rule?
Yes. The Cabin Comfort lets you keep the cab comfortable with the engine off, so you stay under the 5-minute limit and avoid the $300-per-violation fines.
What about federal regulations?
By reducing idle time the Cabin Comfort supports compliance with DOT, EPA, FMCSA and NHTSA rules — helping fleets avoid costly fines.
How much CO₂ do I actually avoid?
Up to 550 lb of CO₂ per year for every hour of idling reduced. A typical driver eliminating 8–10 idle hours per night avoids roughly 65,500 lb of CO₂ per truck per year.
Maintenance
Keeping it running.
How often does the Cabin Comfort need service?
It’s virtually maintenance-free. No oil, no filters, no belts. Designed for longevity and reliability.
Is the system field-tested?
Yes — 6 years of testing in extreme conditions. Real trucks, real fleets, real climates.
What kind of warranty?

NRGPWR Box
NRGPWR BOX questions.
Which model should I pick?
Model 3000 (3,080 Wh, on request) is the compact pick for short outages and portable use. Model 6000 (5,888 Wh) doubles the runtime — best $/Wh on the market at roughly $0.85/Wh.
How fast does the UPS kick in?
6 milliseconds. Fast enough that desktops, NAS, medical equipment and POS systems don’t miss a beat.
Can I charge it from solar?
Yes — 50 A solar input. Connect panels for true off-grid energy independence. AC wall (18 A) and 12 V car (12 A) charging are also supported.
How long does it run a fridge?
8–13 hours on Model 3000; 17–26 hours on Model 6000. Full appliance runtime chart on the NRGPWR Box page.
Financing
Paying for it.
Is financing available?
Yes. We partner with QuickSpark Financial for owner-operators and American Bank Equipment Finance for fleets — everything from a single tractor to enterprise-scale rollouts.
What if my credit isn’t great?
QuickSpark works with multiple funding sources and has special programs for low credit scores and brand-new businesses. Apply once, they shop the right lender.
Will the savings cover the payment?
Most operators structure the payment so the monthly diesel savings ($750–$1,000) cover the financing payment — meaning you’re cash-flow positive from day one. See Financing.
