Why Buy?

It is a good choice as a backup generator for small households, as most household appliances can be operated with it as long as you keep an eye on the load.

Choosing the Right Size 50 Amp Generator

The choice of the right size of a 50 amp generator depends entirely on your needs. If you’ve a motorhome that requires 50 Amps of current, the minimum recommended power is about 4,000 amps. If you’ve several appliances, i.e. a microwave, a television, a refrigerator, and AC, you’ll need a little more wattage.

Here’s how to find the right size portable generator for your needs:

Determine the Size You Need

Generators produce running watts and surge (or, start) watts. To determine your wattage requirements, you must do the following:

  • Make a list of the devices you’re going to power at the same time
  • Make a note of their running watts and additional requirements for the starting wattage. This information can be found in the operating instruction of the individual devices or on the data plates
  • Add up all the running watts. Your generator must deliver as many operating watts
  • Find out which device requires the highest starting wattage. Add this to your total number of starting watts. This new number is the number of starting watts your generator must deliver

Running Time

You want a generator that offers a long-running time with half a charge of fuel. The longer it can operate, the less often you need to refuel. It also means that you’ll get steady power for longer. It’s recommended that you buy a generator that provides at least 10 hours of running time with half a load.

Sockets and Cable Set

Make sure you choose a generator that has enough outlets for all your equipment needs. If you plan to operate a window AC unit, the generator should have a 30 amp socket with a lock.

You also want a generator with a high-performance cable set. These cable sets have four household sockets at one end, which makes an extension cord unnecessary.


Portable generators are heavy. You want to ensure that they come with folding handles and a decent wheel kit to make life easier.

Why You Need a Portable Generator

Generators may seem like a luxury item in general if you don’t live in an area threatened by a natural disaster, but they’re essential for emergency equipment in your home. They provide power in the event of an outage, but that won’t be the only time you’d need to use them, most especially the portable type.

A portable generator can serve a variety of purposes due to its compact design and highly mobile features. Here are a few examples:

  • A portable generator is great for use as a mini-charging station if you drive an electric car
  • You power electric pumps if there’s a power failure and you require water
  • You can power sump pumps to prevent flooding during a severe storm
  • They also enable you to enjoy all your modern conveniences while camping

Frequently Asked Questions

How Many Watts Does a 50 Amp Generator Supply?

A generator with a 50 amp socket has the potential to deliver 12,000 watts (50 amps by 240V). However, not all models can produce this amount of power continuously. For example, the Champion 100297 has a 50 amp socket, but can only put out a peak power of 10000 watts. On the other hand, the Duromax XP12000EH delivers a starting power of 12000 watts before it drops to 9500 running watts.

How Is a 30 Amp Generator Different from Its 50 Amp Counterpart?

The main difference lies in the type of sockets. One has a 30-ampere outlet, the other a 50 amp socket. The difference between these outlets is that a 30 amp outlet has 3 connections, of which only a 120V hot wire is present. A 50 amp socket, on the other hand, has 4 prongs and has two 120V hot wires that supply 2 separate 50 amp, 120V feeds.

Strictly speaking, a 30-amp generator can deliver a maximum of 3,600 watts at 120V (30 amp x 120v). Alternatively, a generator with a 50 amp socket can deliver 12,000 watts at the same voltage (50 amp x 2 x 120V).

Is It Possible to safely connect a 30 Amp RV Into a 50 Amp Plug?

Yes, that’s very possible. But note that these 2 connectors have different configurations. A 30 amp socket has a 3-prong design, while a 50 amp outlet has 4 prongs. So you need an adapter from 30 amp female to 50 amp male (also known as dog bone) to make the connection possible.

How Can I Use a 50 Amp Generator Safely?

To safely operate your generator when camping with a motorhome, you should first make sure that you use high-quality components. Any generator or connections you use must be error-free and of high quality.

Second, you’ll want to ensure that your generator is secured in a flat place. Generators tend to vibrate with the movement of the engine, so make sure that it’s completely level on a safe surface.

Lastly, see to it that you don’t overload your generator. This can be achieved by calculating the watt requirement and comparing it to the wattage of your generator.


If there’s a need to draw as much power as the generator can deliver, with generators that have a 50 amp socket, you can never go wrong. Although they can also be used at home, these generators are dependable workhorses for demanding projects with high output on construction sites, farms, and ranches as well as for large mobile homes and buses.

We chose the Duromax XP12000EH as the number one recommendation for the best 50 amp generator to buy this year. Anyone thinking about a 50 amp generator needs power, and this model has it in abundance, whether you decide to utilize petrol or propane.
