Key Factors for Your Purchase
Power Output and Runtime
First, calculate your total wattage needs. Start by listing the essential devices you must power simultaneously. A unit like the Generac 6864 XD5000E offers a substantial runtime, ideal for prolonged outages.
For lighter duties, such as charging phones and running a small fridge, a lower-wattage inverter model is sufficient. Always check both the starting (peak) and running (rated) watts. This ensures your generator can handle the initial surge of motors without overloading.
Portability and Noise Level
True portability means more than just having wheels. Consider the unit’s total weight and whether it has a sturdy, integrated handle. The Champion 2500-Watt Ultralight Portable Inverter is a prime example of a lightweight design that doesn’t sacrifice power.
Noise is a critical factor, especially for camping or residential use. Look for decibel ratings measured at a standard distance, like 23 feet. Quieter operation, often found in inverter generators, makes for a better neighbor and a more pleasant experience. Learn about specifically quiet options in our guide to the best small diesel inverter generators.
Fuel Type and Efficiency
Diesel fuel is generally less volatile than gasoline and offers superior energy density. This translates to longer runtimes per gallon, a significant advantage during extended outages. Some models, like the DuroStar DS13000MX, offer dual-fuel capability for added flexibility.
Evaluate the fuel tank size against the rated runtime at 50% load. A larger tank may mean less frequent refueling but also adds weight. Diesel engines are also known for their durability and often perform better under continuous heavy loads compared to similarly sized gasoline engines.

Frequently Asked Questions
Are small portable diesel generators quieter than gasoline models?
Not inherently. Noise levels depend more on the engine design, enclosure, and whether it uses inverter technology. Many modern portable diesel and gasoline inverter generators are engineered for quiet operation, with some producing sound levels comparable to a normal conversation. Always check the decibel rating listed by the manufacturer.
What maintenance does a diesel generator require?
Regular maintenance is key to longevity. This includes frequent checks and changes of engine oil and fuel filters, as outlined in your owner’s manual. Diesel generators also benefit from using fuel stabilizers if stored and from running under load periodically to keep the engine healthy. For newcomers, our guide to diesel generators for beginners is a great resource.
Can I use a portable diesel generator to power my entire house?
It depends on the generator’s output and your home’s circuit setup. To safely power a house, you typically need a high-wattage unit (often 10,000 watts or more) and a professionally installed transfer switch. This prevents back-feeding power into the grid, which is dangerous for utility workers. For whole-home backup, ensure the generator has a sufficient rated wattage and the correct outlet, like a 50-amp connection.
How do I calculate the right size generator for my needs?
Start by listing every device you need to power simultaneously and note each item’s starting (surge) and running wattage. Add the running watts for a total, and ensure the largest starting wattage is accounted for. Your generator’s running wattage must exceed your total calculated running load, and its peak wattage must handle the largest starting surge. It’s better to have a slight buffer than to max out the generator’s capacity.
