Intro to 50 Amp Portable Generators

50 Amps portable generators are balanced designs offering plenty of power (up to 10kW/12kW, sometimes even more) and well suited for RVs, camping, home emergency situations, and similar.

Also, 50 Amp portable generators are heavy units, weighing 220+ (100+ kg) easily, and they can't be carried around by a single person - 'portable generator' means that they have wheels and can be towed/pushed by an adult, ATV, truck, car or similar vehicle.

In order to operate properly, these units must be maintained as recommended by their manufacturers - always keep Owner's Manual close and if unsure about something, check it first.

No matter how user-friendly modern power generators are, they are not just 'plug-and-play' devices.

When trying to find 'the best' 50 Amp portable generator, many details determine which unit is actually 'the best' one. Since these details often depend on personal requirements, needs, and habits, it is rather hard to find the best models to suit everyone.

Nonetheless, with so many models on the market, some of them do stand out. Here is our list of the Top 5 best power generators with 120/240 Volts 50 Amp power outlets (14-50R) suitable for powering RVs and all other similar applications.

Frequently Asked Questions (FAQ)

Here are some of the most common Frequently Asked Questions (FAQ) about 50 Amp and other power generators.

Before going into more details about 50 Amp 120/240 power generators, how to connect them to RVs, and the differences between 30 Amps and 50 Amps RVs, please watch this video:

What size generator do I need for 50 Amps?

In theory, one needs a 12000W power generator to run 50 Amps service provided by 120/240V 50A (14-50R) receptacles:

50A x 120V x 2 = 12000W

or

50A x 240V = 12000W

Remember, the 120/240V 50A (14-50R) plug features four prongs - 2x 120V, Ground, and Neutral Wires, and can be used as 120V and 240V.

Is there a generator with a 50 Amp plug?

Yes, there are numerous power generators with 120/240V 50A (14-50R) receptacles that accept 50 Amp plugs (14-50P).

What will a 50 Amp generator run?

The list of tools and appliances depends on the actual wattage that the power generator may provide, but 10-15kW units can power very large RVs and can even be used to power homes during blackouts - when powering homes, be sure to monitor power output regularly, because even such units may be overloaded ...

Will a 9000-watt generator run a 50 Amp camper?

Yes, but You may overload the generator - make a list of devices and appliances in the RV and try not to use them all simultaneously, at least not the most energy-hungry ones.

Will a 30 Amp generator run a 50 Amp camper?

Yes, 30 Amp generator can be hooked to the 50 Amp camper, but just be aware that the maximum usable output power of such a power generator is:

120V x 30A = 3600W

Turn on the AC unit, microwave, and a few smaller devices; the next appliance, for example, the toaster, will overload the generator.

Can I plug my 50 Amp RV into a generator?

Yes, but You need a special 50 Amp generator cord.

How to make a 50 Amp generator cord?

IMHO, go online and buy a 50 Amp generator cord from a reputable brand.

The price difference between getting the required receptacle, plug, and cable and ordering a factory-made cord is negligible - actually, it may be even more expensive to try to make a custom-built 50 Amp generator cord.

Is a 50 Amp generator better than 30 Amp?

It depends on what "better" means - power generators with 120/240V 50A (14-50R) receptacles may transfer more power, but they are open-frame, classic power generators, while smaller 30 Amp power generators are very often inverter power generators with enclosed construction, making them less noisy and more energy efficient...

Will 50 Amps power a house?

Since a power generator with 120/240V 50A (14-50R) receptacles practically means 120V x 100A, 12kW or so power generators may be used to power the house almost completely.

But, they should be connected properly, or else ...

  


Few Final Words

Power generators, even the smallest ones, should be operated outside - these units create fumes that contain very poisonous carbon monoxide, which is a colorless and tasteless gas.

Also, 50A portable generators are not toys despite being designed as user-friendly units. Keep the unit's Owner Guide close by, and if unsure, check the instructions and/or contact support (usually via the manufacturer's official website).

And whatever You do, it is your own responsibility. For short, stay safe.
