8. DuroMax XP12000EH Dual Fuel Generator – Best Propane Output

This is the best generator if you have a steady source of propane. 

This dual fuel generator works on gas and propane. But out of our best picks, this has the best propane output. Propane may not be a readily available source of energy in all areas. So if you have a source of it, there’s no better option than this.

The DuroMax XP12000EH is identical to its predecessor, the Duromax XP13000EH. Also bearing the features common to the DuroMax series– dual fuel workhorse, flexible power sourcing, a DuroMax MX2 maximum power technology, etc.– the DuroMax XP12000EH also has a soundly-complementing system.

In terms of which of the two sources has the least disadvantages, propane stands out. As its natural property, propane has longer storage life so that it does not stick and mess around in the carburetor.

Since the DuroMax XP12000EH distinctly endorses and maintains the propane power section, it leans more towards a propane-induced system. In fairness to its gas power source, it still runs favorably well.

Engine & Performance:

The DuroMax XP12000E is powered by a 457cc OHV engine. Settling at an 18HP rank, it manages to compensate for the lacking 2cc mark. So, it should perform no less than the XP13000EH model.

The Rockpals 12,000’s surge protector enables it to prolong not only its own functionality but also other appliances’. Another proven benefit of this generator is that it can save you fuel.

Power surges are known to increase electricity rates in the place. Without an appliance guard, power surges can blatantly rob currents. And this can damage the appliances in the long run.

In addition to these benefits, the generator has a recoil start. Meaning, it automatically stabilizes its own power at the onset of possible battery drain. However, this feature may also cause the generator to shut down in rare instances.

Engine & Performance:

The Rockpals 12,000, an EPA III and CARB-compliant generator, deems 6.6 gallons of fuel full tank for 8.5 hours of non-stop running. Powered by a 459cc V-OHV Engine, via 4-stroke outlets: 120v on 30A, 120/240v on 30A (locking outlets), 120V on 20A (GFCI household outlets), and 120/240V on 50A.

It starts up at 12,000 watts and continues at 9,000 watts from gas power; it starts at 10,800 watts and continues at 8,100 from propane power.

Noise Level: 

Fortunately, despite its oversized muffler that makes it a bit heavier than usual, the Rockpals 12,000 is a certified quiet generator. Not louder than a vacuum cleaner, its motor operation volume ranges between 75-78 decibels.

Another notable feature of the Generac 5802 is being a temporary power provider. And, as mentioned earlier, it works best in emergencies.

Even with a large capacity fuel tank, it is still proven to operate for short intervals. Thus, experts suggest cooling it every 2-3 hours. After all, it’s a CARB-compliant engine, so it should not backfire easily.

Engine & Performance:

The Generac 5802 is powered by a 220cc OHVI engine that is known for its light and versatile functioning command. Considered to be sufficiently powerful, this engine class fully maximizes pressure using an automotive force to prolong engine life.

With that, it easily responds to light electric start touch. With a full large capacity steel tank of 4.5 gallons, it can run for up to 13 hours (interrupted) at a 50% load. Its starting mark falls at 5,000 watts, while its running mark is at 4,000 watts.

Noise Level: 

The Generac 5802’s fails at a 78-80 decibel range. This is further helped by its anti-vibration fold-down handle and never-flat wheels. Nevertheless, full pressure is concentrated in its OHVI engine. Ultimately, in the event of pressure leakage, its PowerBar monitor gives out a beep.

How to Choose the Right Size 50 Amp Generator (Buying Guide for the Best 50 amp Generator)

Either you’re buying a 50 map generator for your RV or homes, you have to buy the right size. And that’s for two reasons. One, to ensure you have enough prowess for your appliances. And two, to save money. Because buying more than what you need is a waste of money. 

You have to determine how many appliances you need to start up. And are you going to use them all at the same time? 

You need to know the starting watts and the running watts of the generator. Then alternatively, make another rundown of the starting watts and the running watts of all the appliances that you need to run.

Remember that the starting watts is what you need to “start off” an appliance. And the running watts are what’s needed to maintain them. You can sum the starting watts and the running watts of your appliances. And compare them to that of the generator. Ensure that the generator has enough power to fill in these numbers. 

This will help you decide if you don’t need all the 12000 watts that you can get from a 50 amp generator.

Starting Watts vs Running Watts

To be able to determine home many appliances your 50 amp generator can handle, you have to determine the starting watts and the running watts of each appliance.

Simply put, starting watts are the wattage needed to start an appliance. Starting watts are also referred to as surge watts or peak watts. 

And running watts are the wattage needed to maintain the appliance running. It’s the amount of wattage that an appliance will require to prevent it from failing

Appliances with a motor such as an air conditioner will require more starting watts than other appliances. After that power surge, the energy consumption decreases.

So when using a generator, which is more important, the starting watts or the running watts. Both are important. And to be able to determine if your 50 amp generator can handle the surge, compute all the starting watts of the appliance that you intend to run at the same time.

But take note that though 50 amp generators are larger and have a bigger capacity, it’s still not advisable to power ALL of our alliances at the same time. So you still have to prioritize.

Why You Should Buy 50 Amp Generator

Price-wise, a compact generator might seem a good deal. You might even argue that it’s enough for emergencies.

But it wouldn’t be enough to power all the appliances that you need, in case of a blackout. And you need a generator that has a higher watt vs the total starting and running watts of all your appliances. 

This will ensure that you can run each sufficiently. And if you’re going to run several appliances simultaneously, you need a 50 amp generator.

Even if you’re not going to run all of your appliances at the same time, a portable generator can only supply 25 % percent of your energy needs.

50 Amp Generator

Which Generator Size is Best to Use for Your 50 Amp RV?

Powering the RV is not as easy as you think. Many RV owners, instead of pumping electric current into their RVs, end up doing the opposite. RVs have varied electrical needs and services. Hitting a one-ampere degree should be insufficient if you’re actually aiming for a sustained wattage performance. 

The overarching means for fully understanding the RV’s electric needs is to scrutinize the nitty-gritty of your 50 amp RV system. Only by getting the hang of it can you identify the perfect generator size for your 50 amp RV.

Generator Safety Tips

The main things to look at when using generators are carbon monoxide poisoning, electric shock, and fire. Improper use can expose you to these dangers.

Carbon monoxide is a colorless and odorless gas. That’s why it’s quite dangerous as you do not know you’re inhaling it already. You’ll only realize it once you get dizzy. And in case this happens, you have to get fresh air asap and call for medical help. 

So to be able to use a generator safely at home, here are some life-saving tips.

  1. Ensure that the generator is placed on a flat dry surface. You must prevent it from getting wet. Ensure that it’s covered with tarps and supported with. It will prevent it from getting soaked with rainwater.
  2. Avoid using your generator in rainy or wet conditions. 
  3. Never touch the generator with wet hands.
  4. Before refueling, turn off the generator and allow it to cool down first.
  5. Use an approved safety can for storing generator fuel.
  6. Use only the type of fuel recommended for use on generators.
  7. Plug heavy-duty appliances directly into the generator. Otherwise, use a heavy-duty cord to connect the appliance to the generator. Ensure that it’s rated in watts and equal to the total watts of the appliances. Ensure that the cord will be able to handle the power surge. 
  8. Before connecting the cord, check if there are tears, cracks, or any damage. Ensure that it has three prongs and a grounding pin. Grounded generators can prevent shocks and electrocutions.
  9. Never plug in a generator to a wall outlet. This can put you and other people at risk of electrocution. Only licensed electricians are allowed to do so and they use special equipment for this. So don’t be a daredevil and just follow the rules.
  10. Always read the manufacturer’s instructions. And be careful not to overload your generator.
  11.  To avoid overheating, try to run all your appliances at different times. Make a schedule on how to run them in a staggered manner.
  12. To avoid carbon monoxide poisoning, these generators should be used outside and placed away from doors and windows. Carbon monoxide must not find an entryway into your homes. Generators should be located at least 15 ft away from doors, windows, or any entry point.
  13. Don’t use generators or other charcoal burning tools inside your homes. It should never be used inside an enclosed area due to the high risk of carbon monoxide poisoning.
  14. If you start to feel dizzy, it’s a sign that you have inhaled carbon monoxide. Get fresh air right away.
  15. Carbon monoxide is odorless. So to prevent inhalation of these toxic fumes, you can install carbon monoxide alarms on the entryway of your home or in your sleeping areas. 
  16. And if the carbon monoxide alarm beeps, make sure to get fresh air asap.
  17.  Always check first before using the generator.
  18.  Do a routine inspection and maintenance of your generators. Check for any cracks or leaks. And If are damaged parts, fix or replace them immediately,
  19. It’s advisable to schedule yearly maintenance of your generators. You can also commission a professional to do it. 
  20. You may run the generator before the storm season begins. Use fresh fuel and check if it is running efficiently. It’s frustrating to find out that it’s not working anymore once you need it. 
  21. Maintain an adequate supply of fuel. You can also check with your local area regulations on fuel and safety. There might be restrictions as to how much fuel you can keep in your homes. And also know your generator’s fuel consumption per appliance. 

Calculating the Result

To better grasp and measure wattage, you first need to look into the  50 amp RV system. Its system usually comprises a ground wire, two 120v (volt) wires, and neutralizing wires. So when you channel the RV to a generator, you are generating power between 120-240v. Since the 120v is the main surge, it shall be multiplied by two (representing the two surges in the range) that is: 2 x 120v. 

Now, to come up with the total required wattage size, you will have to lay the figures in this formula: 50 (ampere size) x 2 (midranges) x 120v (the main surge), totaling to 12,000 wattage size. 

The highest demand for wattage or generator size, therefore, is 12,000. But that does not mean you’ll have to purchase such a powerful generator because after all, the greatest determinant would be the total kWh needs per appliance. 

If you were keen to observe, our recommended wattage size range– 4,000-8,000- accurately falls within the 12,000 total generator size. 

Here’s a Honda chart for a guided estimation of the generator size. 


Can I use a generator even if it’s low on fuel?

That would not be recommended. You either have to shut it down in intervals to allow it to cool. Then, you will have to refuel it. Some models like that of DuroMax and Champion have backup power sources and low-oil auto-shutoff. But, you can’t be fully dependent on these features if you want the generator life to be preserved. 

Which is the best fuel source- gasoline or propane?

That is entirely dependent on the carburetor. But based on recommendations, propane proves to be mess-free, anti-stick and smooth in terms of delivering power.

What is the difference between starting watts and running watts?

Starting watts are the needed fuel or energy to start up an appliance. Running watts, on the other hand, are the watts needed to keep an appliance running. 

What is the difference between a 30 amp and 50 amp generator?

The difference is in the design and the number of watts it can provide. For the design, a 50 amp generator has 4 prongs while a 30 amp only has three. Also,  a 50 amp generator can provide 12000 watts. A 30 amp generator, on the other hand, can only provide you 3600 watts.
