What to pay attention to when choosing a dual fuel generator
Here are the most important factors to consider when you are looking for a dual fuel generator:
- The first factor is the ability to cope with a heavy load. The generator should be able to power a lot of devices at the same time and run for a long time without any technical problems. The most powerful in this matter is DuroMax XP12000EH (review). It has plenty of power options and can run nonstop all day.
- The generator must be highly reliable in emergencies — especially during power outages and natural disasters, like hurricanes, etc. The generator should be your faithful friend, companion in a difficult moment. The Champion Power Equipment 76533 (review) will be set up due to wheels in less than 15 mins without any problems, which is vital, especially during hurricane wind. Thanks to the easy electric start and non-stop working time (14/15 hours a day), the Champion can become a real lifesaver for you.
- The next very important criterion is an easy electric start. Thus, the generator should start quickly, especially when you are in a rush to supply electricity to your home. The best model in this category is DuroMax XP4850EH (review). The generator starts up very easily with the key, has a recoil start, in case of a battery drain-out, and last, but not least — the generator keeps your beer cold.
- Efficiency. The unit should be quite economical — it takes the least fuel, but produces the same amount of electricity compared to other generators. The DuroStar DS10000EH (review) offers the greatest efficiency: the generator runs all night without having to fill the tank thanks to 10000 watts wattage and economical fuel consumption.
- The fifth aspect is low noise. Your dream dual fuel generator should operate quietly If you don’t want to start a real war between neighbors. The Champion Power Equipment 100263 (review) is the quietest on the list. Some people even call him quiet, like a whisper. You can even talk while the generator works, so the barbeque is not canceled when the lights are turned off!
Some additional points will also make your dual fuel generator purchase better:
Additional factors to pay attention to
- Grounding scheme system — for your safety. Grounding is used to protect from electric shock.
- Compact size — this will help the generator take up little space and at the same time be functional.
- Well-designed — when all parts and details of the generator are well built and work perfectly.
- Stable electricity generation — it concerns uninterrupted power supply, activity on the voltmeter, power in outlets, etc.
- Plenty of power options — each generator has a rated (real) and maximum power option. A quality generator can operate at maximum power for as long as possible without overloading. However, it must be remembered that the long-term operation of any generator at the “limit of possibilities” shortens its service life.
- Trouble-free oil change and operation of oil filters — the oil must be changed easily and the filters work smoothly.
- Easy to move around — even older people should be able to move the generator without problems.
- Battery charging — the battery must be initially charged and easily charged throughout the “life” of the generator.
- Lightweight — the generator shouldn’t be critically heavy to be able to move around.
- No leaking — naturally, the generator shouldn’t leak for the safety of operation of all parts of the unit.
- Available replacement parts for this unit and replacement process — the generator unit must assume the availability of spare parts and propose a replacement process.
We picked the best models based on these criteria and made a detailed review of each.

Just like a Champion Power Equipment 76533 (review), DuroMax XP12000EH has a quick start too: after turning the key, the generator starts right up in less than 3 seconds. Like all DuroMax generators, models XP12000EH and XP4850EH (review) both are approved by EPA and CARB for use in all 50 States. Like any engines that burn combustible fuel, power generators can produce toxic fumes that are released into the atmosphere. CARB tries to limit California’s air pollution caused by these harmful gases. EPA also protects the atmosphere, but CARB rules are usually stricter than EPA rules. Many generators are labeled as “CARB-compliant.” Choose those even if you don’t live in California, because they’re better for the environment and legal for use everywhere in the United States.
The only thing you should know before buying this generator is that it is cordless. That is why it will be necessary to buy or make the special hose that connects to the propane tank, the cord that connects it to any amp plug, and the ground wire.

An additional useful generator function is an auto-idle, which is easy to apply with a flick of a switch, and which protects from overload. The system is quite simple: a sensor looks at the output of the generator to determine if there is any current flowing, which would represent a load. If nothing is plugged in, there will be no current. When a consumer is plugged in, the current will flow. Also, DuroStar has an automatic low oil shutoff, that won’t allow the generator to wear out quickly. Moreover, it is approved by EPA and CARB for use in all 50 States as DuroMax XP12000EH (review). Like any engines that burn combustible fuel, power generators can produce toxic fumes that are released into the atmosphere.

It is also a winning model because it is super easy to install and use. And last, but not least — the generator always keeps your beer cold.
Note: If you’re planning to run the AC unit for a trailer or RV, you will need the DuroMax XP 3030 RV Power Adapter. Plug the 4 prong side into the generator and plug the trailer into the 3 prong side of the adapter. Turn the power switch to a 120V setting, not 120/240. If you don’t go this route the breaker on the generator will throw every time you try to turn on your AC unit.
Dual fuel generator do’s and don’ts
When you buy a dual fuel generator for the first time, there are some “Do’s and Don’ts” you should know to make your purchase experience better and easier. Here is a list of actual tips and prohibitions for setting up a dual fuel generator for the first time in your life.
- Always try to use the dual fuel generator outside for your safety, or keep it indoors but strictly in a spacious room with working ventilation, as the generator emits carbon monoxide.
- Keep the generator dry. Do not use it during the rain and never touch it with wet hands. Keep the generator under a canopy and protect it from wind and rain, otherwise, fire or electric shock may result. Also, a wet environment is dangerous for the engine.
- Wear the proper clothing. When working with the generator, it is best to use special protective gloves, closed-toe shoes, jeans, or heavy-duty pants. Such precautions will help to avoid electric shock.
- Plug appliances directly into the generator or use an outdoor-rated extension lead. Check that the entire cord is free of cuts and that the plug has all three prongs, especially an earthing pin.
- Before refueling the generator, turn it off and let it cool down. Fuel spilled on hot engine parts could ignite.
- Do not overload the dual fuel generator. Before buying a portable generator, you need to calculate the amount of power you are going to need.
- Never try to power the house wiring by plugging the generator into a wall outlet, it is known as backfeeding. This is extremely dangerous and there is a risk to utility workers and neighbors who are served by the same utility transformer.
- Avoid creating a fire hazard. Store fuel for your generator in properly labeled non-glass safety containers and keep it away from children.
