To learn, whether you can run all these at the same time you need to know the power consumption of each appliance in your home.

There are some universal rules and precautions you need to follow when you want to run your generator safely.

The best document on this topic is the OSHA Fact Sheet: Using Portable Generators Safely and here is a quick summary:

• Never attach a generator directly to the electrical system of a structure (home, office, trailer, etc.) unless a qualified electrician has properly installed the generator with a transfer switch.
• Always plug electrical appliances directly into the generator using the manufacturer’s supplied cords or extension cords that are grounded (3-pronged). Inspect the cords to make sure they are fully intact and not damaged, cut or abraded.
• Use ground fault circuit interrupters (GFCIs), especially where electrical equipment is used in or around wet or damp locations. GFCIs shut off power when an electrical current is detected outside normal paths.
• Never use a generator indoors or in enclosed spaces such as garages, crawl spaces, and basements. NOTE: Open windows and doors may NOT prevent CO from building up when a generator is located in an enclosed space.
• If you or others show symptoms of CO poisoning—dizziness, headaches, nausea, tiredness – get to fresh air immediately and seek medical attention.
• Keep fuel containers away from flame producing and heat generating devices (such as the generator itself, water heaters, cigarettes, lighters, and matches).

For more safety tips and precautions, read this article called “Generators and Heating Safety” from New York State Department of Health or the OSHA Fact Sheet: Using Portable Generators Safely.

In general, a refrigerator takes around 1200 surge watts at the beginning while the compressor kicks in and then it gradually drops down to around 200 running watts. 

As you can see, every generator mentioned in this article could run a mid-sized refrigerator.

If you choose at least a 2000 starting watts inverter generator (Yamaha EF2000iSv2, WEN 56200i, or Generac GP2200i), you can power any modern refrigerator with a freezer easily.

Most fridges require about 800 – 1200 starting watts and 2000 watts is more than enough to power them safely.

Also, if your generator has a high total harmonic distortion, your fridge (especially if you have a modern type) may get damaged (that is why we recommend getting an inverter type of generator).

The size of a generator depends on the type of fridge you want to power:

• While modern appliances have much lower power consumption (around 300 – 400 watts), even while the compressor starts to kick in, the older types of fridges are going to need a bigger power supply (around 300 – 1,200 watts).
• Another aspect that will affect the required size of your generator is whether your fridge also comes with a freezer. In such a case it will require even more power (add 80 – 100 watts to those numbers mentioned above).

Learn more about the power consumption of different types of refrigerators in our guide FAQ: What Size Generator Do I Need to Run a Refrigerator?

In general, a common microwave needs around 1000 watts to operate. 

A 2000 watt generator provides at least 2000 running and 2200 starting watts so you can run your microwave pretty easily.

Just don’t forget to check the nameplate on your appliance to learn the precise wattage requirements.

This question doesn’t have a universal answer as each generator has unique fuel consumption and capacity of the fuel tank. 

From our experience, an average 2,000 watt generator runs for approximately 7.4 hours on a 50% load.

This number is a median that we got after looking at the run time of over 20 generators that provide around 2,000 running watts.

Here are some examples:

• Honda EU2200i – 1,800 running watts – 6 hr on a 50% load (0.95 gal)
• WEN 56235i – 1,900 running watts – 10.5 hr on a 25% load (1.0 gal)
• WEN 56225i – 1,800 running watts – 9.2 hr on a 25% load (1.0 gal)
• Generac GP2200i – 1,700 running watts – 10.7 hr on a 25% load (1.2 gal)
• Lifan ESI2500iER – 2,400 running watts – 14 hr on a 50% load (1.5 gal)
• Generac GP3000i – 2,300 running watts – 4.5 hr on a 50% load (1.06 gal)
• Yamaha EF2000iSv2 – 1,600 running watts – 10.5 hr on a 25% load (1.1 gal)
• RYOBI 2300 – 1,800 running watts – 8 hr on a 50% load (1.2 gal)
• Westinghouse iGen2200 – 1,800 running watts – 12 hr on a 25% load (1.2 gal)

In general, a 2000 running watts generator doesn’t provide enough power to run a heat pump or electric furnace. 

However, answering this question is hard without knowing the exact running and starting watts required by your electric appliance.

Please, contact the manufacturer of your pump or furnace to learn more info on its wattage requirements.

Sadly, there is not a single answer to this question. 

To learn, whether you can run your welder on a 2000 watt portable generator you need to know the power requirements of your welder (see the data tag or user manual you got to your welder). 

However, based on the information we were able to learn, the best option is to get a special generator that has been manufactured for welding purposes to be able to harness the full potential of your welder.

According to one of the most trusted welding websites out there, you will need:

• Up to 160A current level – 7000 watts minimum
• 180–200A current level – 8000 watts minimum
• 210-250A current level – 13,000 watts minimum

In general, a 2000 – 2400 running watts generator should provide enough power to run a very small air compressor (1/4 horse power) without any issues. 

However, answering this question is really hard without knowing the exact running and starting watts required by your air compressor.

We have found rough estimates for different types of compressors:

• 1/2 Horse Power – It takes 975 running watts and 1600 starting watts.
• 1 Horse Power – It takes 1600 running watts and 4500 starting watts.

As you can see in the estimates above, the issue is not running watts but starting watts. To get precise numbers, you will need to find the voltage, amperage, and horsepower information on the info-plate of your compressor.

Then, all it takes to learn the required wattage is to apply this equation:

Watts (W or kW) = Volts (V) x Amps (A)

Definitely. As long as your generator is an inverter with a low total harmonic distortion, then you can run your TV safely on a 2000 watt generator.

Here are some rough estimates of wattage requirements of various TVs:

• Tube type – It takes 300 running watts and 300 starting watts.
• Flat Screen (20”) – It takes 120 running watts and 120 starting watts.
• Flat Screen (46″) –  It takes 190 running watts and 190 starting watts.

As you can see, you will have enough spare power to run your DVD player which takes approximately 350 running and 350 starting watts as well.

In general, a 2000 – 2400 running watts generator should provide enough power to run a  small RV AC unit (11000 BTU) without any issues. 

However, answering this question is really hard without knowing the exact running and starting watts required by your AC unit.

We have found rough estimates for different types of RV air conditioning units:

• 11000 BTU – It takes 1050 running watts and 1600 starting watts.
• 13000 BTU – It takes 1800 running watts and 2800 starting watts.
• 15000 BTU – It takes 2000 running watts and 3300 starting watts.

As you can see in the estimates above, the issue is not running watts but starting watts. To get the precise numbers, you will need to find the voltage, and amperage information on the info-plate of your RV AC unit.

Then, all it takes to learn the required wattage is to apply this equation:

Watts (W or kW) = Volts (V) x Amps (A)

The answer to this question is not that simple. In general, a rough estimate of power requirements of a heavy-duty 7.25″ circular saw are as follows:

• 1400 running watts
• 2300 starting watts

As you can see, as long as your generator offers at least 2500 starting watts (we rather recommend getting slightly more power than needed), you should be able to run your machine on this type of generator.

A rough estimate of the energy requirements of a space heater is as follows:

• 1800 running watts
• 1800 starting watts

As you can see, you can easily run your space heater with a 2000 – 2400 running watts generator. 

Just don’t forget to double-check the name tag on your appliance to learn the precise wattage requirements.

Usually, a 2000 – 2400 running watts generator should provide enough power to run a very small sump pump (1/3 horse power) without any issues. 

However, answering this question is hard without knowing the exact running and starting watts required by your pump.

We have found rough estimates for different types of sump pumps:

• 1/3 Horse Power – It takes 800 running watts and 1300 starting watts.
• 1/2 Horse Power – It takes 1050 running watts and 2150 starting watts.

As you can see in the estimates above, the issue is not running watts but starting watts. To get the precise numbers, you will need to find the voltage, amperage, and horsepower information on the info-plate of your pump.

Then, all it takes to learn the required wattage is to apply this equation:

Watts (W or kW) = Volts (V) x Amps (A)

Just keep in mind that your sump pump will probably require a 240V outlet on your generator. You can read more on this topic here:

• What Size Generator Do I Need for My Sump Pump?
• Can a Generator Run a Sump Pump? (Examples)

In general, a 2000 – 2400 running watts generator should provide enough power to run a very small well pump (1/3 horsepower) without any issues. 

However, answering this question is hard without knowing the exact running and starting watts required by your water pump.

We have found rough estimates for different types of pumps:

• 1/3 Horse Power – It takes 750 running watts and 1500 starting watts.
• 1/2 Horse Power – It takes 1000 running watts and 2100 starting watts.
• 3/4 Horse Power – It takes 1500 running watts and 3000 starting watts.
• 1 Horse Power – It takes 2000 running watts and 4000 starting watts.
• 1 & 1/2 Horse Power – It takes 2500 running watts and 5000 starting watts.

As you can see in the estimates above, the issue is not running watts but starting watts. To get the precise numbers, you will need to find the voltage, amperage, and horsepower information on the info-plate of your pump.

Then, all it takes to learn the required wattage is to apply this equation:

Watts (W or kW) = Volts (V) x Amps (A)

There is no way a 2000 watt generator would provide enough power to run a central AC unit. 

We would rather go for a very small emergency window AC unit as 2000 watt generators may have too little starting power.

However, the answer to this question depends on the number of running and starting watts your AC unit requires.

These numbers vary from one unit to another and are based on the cooling ability of individual models and brands. 

That is why you need to look for the following data on the name tag of your central AC unit:

1. LRA (Locked Rotor Amps) – This number represents the current you can expect under starting conditions when you apply full voltage.
2. RLA (Rated Load Amps) – This number represents the maximum current a compressor should draw under any operating conditions.
3. FLA (Full Load Amps) – This number represents the same as the Rated Load Amps.

You need to take into consideration the amps for both the compressor and the fan unit. To determine, if your 2000 watt generator can run a central AC, please consult its manufacturer or a professional electrician.

To discover the exact power needs of your AC unit, check out this helpful guide: How Many Watts Do 5,000 – 18,000 BTU Air Conditioners Use?

Keep in mind that a typical central air unit runs on a 208/240 volts and is often permanently mounted and hardwired into the electrical system of your house. 

That is why to safely run this electronic appliance you need to connect your generator through a transfer switch.

You should always connect your generator through a transfer switch if you don’t want to damage your appliances or endanger people who may be working on electric lines in your neighborhood.

Usually, a 2000 watt gasoline generator has a 4-stroke engine. 

If this is the case, you will need to use either SAE 30 (if you live in a warmer climate) or SAE 10W-30 if you are going to use it in a colder climate (do not forget to double-check with your owner´s manual).

However, there are several things you need to consider while choosing the oil for your machine:

• Whether you got a 2-stroke or a 4-stroke engine
• Starting and operating temperatures
• Type of fuel your machine runs on
• Certifications and classifications of the oil
• The reputation of the brand and company producing the oil

If you need to learn more information on how to choose the best oil for your generator, then consult our guide that is available right here. 

In general, a 2000 watt generator provides approximately 16 amps, in case of 120 volts or 8 amps in case of 240 volts.

However, we haven’t seen a 2000 watt generator that would provide 240 volts. To learn more, you should check out the owner´s manual for the machine you want to buy.

Identifying how many amps there are in a 2000 running watt generator is a very simple process. All you have to do is to apply the following formula:

Amps (A) = Watts (W or kW) / Volts (V)

You need to divide the wattage by the voltage. So, in this case you need to divide 2000 by 120 or 240 to get the correct numbers.

Here is our handy cheat sheet:

• 500 Watts, 120 V = 4.2 A, 240 V = 2.1 A
• 1000 Watts, 120 V = 8.3 A, 240 V = 4.2 A
• 2000 Watts, 120 V = 16.7 A, 240 V = 8.3 A
• 3000 Watts, 120 V = 25.0 A, 240 V = 12.5 A
• 4000 Watts, 120 V = 33.3 A, 240 V = 16.7 A
• 5000 Watts, 120 V = 41.7 A, 240 V = 20.8 A
• 6000 Watts, 120 V = 50.0 A, 240 V = 25.0 A
• 7000 Watts, 120 V = 58.3 A, 240 V = 29.2 A
• 8000 Watts, 120 V = 66.7 A, 240 V = 33.3 A
• 9000 Watts, 120 V = 75.0 A, 240 V = 37.5 A
• 10000 Watts, 120 V = 83.3 A, 240 V = 41.7 A
• 12000 Watts, 120 V = 100.0 A, 240 V = 50.0 A
• 14000 Watts, 120 V = 116.7 A, 240 V = 58.3 A
• 16000 Watts, 120 V = 133.3 A, 240 V = 66.7 A

One of the most notable advantages of inverter generators is that they’re perfect for powering small devices, such as computers, televisions, and smartphones.

If you prioritize things like fuel efficiency, quietness, portability, and the ability to safely power sensitive electronics, you really can’t go wrong with an inverter generator.

While some traditional generators can produce upwards of 17,000 watts, inverter generators don’t usually reach figures higher than around 7,000.

PROS OF AN INVERTER GENERATOR:

• Produces power with significantly lower THD
• Lighter and smaller
• More energy efficient than traditional generators
• Much lower fuel consumption
• Parallel capability
• Safe for sensitive electronics like laptops or mobile phones
• Quieter than traditional generators

CONS OF AN INVERTER GENERATOR:

• Significantly more expensive than traditional generators

To read more about how to pick the best generator for your home, check out our helpful guide linked above. 

We recommend you consider the following features:

Fuel Type – For job contractors, we recommend generators that are running on diesel as this type of fuel is more frequently used in other machines that are usually present on the job site.

This way, your fuel management will be much easier.

Long run time – The worst thing that can happen on a job site is downtime as it leads to profit loss. Every refueling takes your machine out of service for some time.

Therefore, it is vital to get a generator that can run for a whole shift without the need to refuel. This way, you can do the refueling with basic maintenance after the work shift is over.

Large gas tank – Although a large gas tank will diminish the portability of your generator, it will enable you to run it for a longer period without the need to refuel.

Automatic idle control – The automatic idle control (also known as Eco Throttle or Smart Throttle) can save you a lot of fuel costs and can reduce the noise of your generator.

It automatically adapts the rotations of your engine to the actual load. If your generator runs idle, this system can significantly reduce the number of rotations per minute.

There is no single answer to this question. There are several features of your 2000 watt generator you need to consider while choosing your transfer switch.

We are going to cover this topic soon but in the meantime, feel free to read this comprehensive guide from Electric Generators Direct: How to Pick the Perfect Manual Transfer Switch or this one from GeneratorGrid: Transfer Switch for Your Portable Generator: Buyer’s Guide

If you are looking for an RV generator, our advice is to choose a machine that is powerful but still quiet. Ideally, go for an inverter generator. There are many inverters in this category of generators but these 3 are the quietest:

1. Westinghouse iGen2500 Camo (1074+ Reviews)
2. Westinghouse iPro2500 (23+ Reviews)
3. Yamaha EF2400iSHC (111+ Reviews)

Sadly, there are no RV ready generators in this category. That is why you need to get a necessary set of adapters (also called dogbones) to easily connect your RV to any machine on this list through either a 20 or a 30 amp outlet.

So pick a generator that fits your needs the most and if it is not RV ready, don’t forget to get the correct adapter.

Finding reliable information on the “noisiness” of generators is a tough job to do. However, based on our findings, we can list the following machines as “quietest”:

1. Westinghouse iGen2500 Camo (1074+ Reviews)
2. Westinghouse iPro2500 (23+ Reviews)
3. Yamaha EF2400iSHC (111+ Reviews)

In general, if you want a portable generator that is powerful but also quiet at the same time, then go for an inverter. Sadly, these machines are much more expensive than regular generators.

If you are looking for a 2000 -2400 running watts generator that offers the most comfortable electric start, then we have only two options for you to choose from:

1. Lifan Energy Storm ESI2000iER (2000 running / 2200 starting watts)
2. Lifan Energy Storm ESI2500iER-EFI (2400 running / 2500 starting watts)

Both machines are almost the same and offer a remote start. So choose one according to the maximum starting and running watts you require.

While going over our database of 2000 – 2400 running watts generators, we haven’t identified any generator that runs on diesel. If you still need a diesel powered generator, you would need to increase the running watts category:

• Yanmar YDG2700N (2500 running watts generator)

Just expect to pay a lot as diesel generators are usually on a much more expensive side when compared to gasoline powered machines.

We haven’t found any 2000 watt generator that runs on propane. If you still need a propane powered generator, you would need to either increase or decrease the running watts category:

• DuroMax XP2000EH (dual fuel – 1600 running watts generator)
• All Power America APG3535CN (propane – 2800 running watts generator)

All these machines provide a good quality-vs-price ratio.

If you are looking for the best inverter generator that provides 2000 – 2400 running watts, then there are many options for you to choose from.

Based on our research, the best inverters in this category are:

1. Lifan Energy Storm ESI2500iER-EFI (2400 running / 2500 starting watts)
2. Westinghouse iGen2500 Camo (2200 running / 2500 starting watts)

Just keep in mind that although inverters are running quietly, they are on the expensive side.
