Your Truck’s Best Friend: A Comprehensive Buying Guide for APUs
What is an APU for Trucks?
APU stands for Auxiliary Power Unit. Think of it as a mini-power plant for your truck. It gives your rig extra electricity without needing to run the main engine. This means you can power your cab’s amenities, like lights, air conditioning, and electronics, while the big engine is off. It saves fuel and reduces engine wear.
Key Features to Look For
Power Output (Wattage)
APUs have different power outputs. More wattage means you can run more devices at once. If you need to power a microwave and a powerful AC unit, you’ll need a higher wattage APU. For basic needs like charging your phone and running a small fan, a lower wattage might be enough.
Fuel Type
Most truck APUs run on diesel, just like your truck. Some might use gasoline or even battery power. Diesel is common because it’s readily available at truck stops. Battery-powered APUs are quieter and don’t produce emissions, but they need to be recharged.
Noise Level
A quiet APU is a happy driver’s APU. Look for models that advertise low decibel (dB) ratings. This is important for resting comfortably in your sleeper. Some APUs have noise reduction features like soundproofing or special mufflers.
Fuel Efficiency
Even though it saves fuel by not running the main engine, the APU itself uses fuel. Check the APU’s fuel consumption rate. A more fuel-efficient APU will cost you less in the long run.
Cooling/Heating Capabilities
Does the APU offer air conditioning and heating? This is a big one for driver comfort. Some APUs only provide electricity, and you’ll need separate heating or cooling systems. Integrated systems are more convenient.
Battery Charging Capabilities
Many APUs can also charge your truck’s batteries. This is a great bonus feature that keeps your truck ready to start.
Important Materials
APUs are built to be tough. They use strong metals like steel and aluminum for their casings and internal components. High-quality wiring and durable hoses are also crucial for longevity. The generator itself will have copper windings for efficient electricity production.
Factors That Improve or Reduce Quality
Brand Reputation
Sticking with well-known and trusted APU brands often means better quality and customer support. Research brands that have a good track record in the trucking industry.
Build Quality and Durability
A well-built APU will have sturdy construction and resist vibrations and harsh weather. Look for solid welds, secure mounting points, and protection against the elements. Cheaper, flimsy materials can break down faster.
Maintenance Requirements
Some APUs require more frequent maintenance than others. Simple maintenance is good. Complex or costly maintenance can be a hassle and add to your overall costs. Check the recommended service intervals.
Warranty
A good warranty shows the manufacturer stands behind their product. A longer warranty period usually indicates higher confidence in the APU’s reliability.
User Experience and Use Cases
Driver Comfort
The biggest win for drivers is comfort. APUs allow drivers to stay cool in the summer and warm in the winter without idling the main engine. This means better sleep and less stress.
Fuel Savings
By avoiding unnecessary engine idling, drivers save a significant amount of money on fuel. This can add up quickly over a year.
Reduced Engine Wear
Idling an engine causes more wear and tear than running it at optimal speeds. An APU reduces idling time, which extends the life of your truck’s engine.
Powering Accessories
Beyond comfort, APUs can power microwaves, coffee makers, laptops, TVs, and other electronics, making life on the road much more convenient.
Environmental Benefits
Less idling means fewer emissions. APUs contribute to cleaner air.

A: Installation can be complex and often requires professional help. It involves connecting fuel lines, electrical systems, and mounting the unit securely.
Q: How much fuel does an APU use compared to idling the main engine?
A: APUs are designed to be much more fuel-efficient. They use a fraction of the fuel that idling your truck’s engine would consume.
Q: Can I use an APU in all weather conditions?
A: Most APUs are built to withstand various weather conditions, but it’s always good to check the specific model’s specifications for extreme temperatures.
Q: What kind of maintenance does an APU need?
A: Maintenance usually involves regular oil changes, filter replacements, and checking electrical connections. It’s generally less intensive than main engine maintenance.
Q: Will an APU affect my truck’s warranty?
A: It’s important to check your truck manufacturer’s warranty policy. Some may void certain engine warranties if not installed by certified technicians.
Q: How long does a typical truck APU last?
A: With proper maintenance, a good quality APU can last for many years, often 10 years or more.
Q: Do APUs require special fuel?
A: Most APUs use standard diesel fuel, the same fuel your truck uses. Some battery models do not use fuel at all.
Q: Can an APU power all my truck’s electronics?
A: The ability to power electronics depends on the APU’s wattage. You need to match the APU’s output to your power needs.
Q: Are there any government incentives for installing APUs?
