2000w vs 3000w: Should I get a 2000 or 3000W inverter? (Tips)

When you are comparing the two sizes, about the only difference is the number of appliances you can run at one time. Being larger, the 3000W should run cooler and give you a little bit more freedom as you camp.

This purchase will depend on what you want to run. You may not need the 3000W if you are not running the AC and the microwave through the inverter. Plus, your purchase will depend on how fast you want to deplete your battery power.

To learn more about this topic, just continue to read our article. It has the information you want to know about so you can make the right purchase for your situation. Take a few minutes to see how this information helps you decide.

Should I Get a 2000 Or 3000W Inverter?


This is a question that only you can answer correctly. The reason we say that is that you will be the one deciding how much power you will be drawing at any one time.

The larger inverter is usually the best route to take because it can provide more power for a longer period of time. This is good even if you are not running your big-ticket appliances through the inverter.

The larger product will have the power ready whenever you need it. You cannot say the same thing about the 2000W. While it is good, it may not be as reliable as the 3000W option.

Or if you have a smaller trailer with very few electrical devices that need to use the inverter, then the 2000W would be the better choice. You have to look at what you will plug into the inverter and how long you need the power supply before you can decide which of the two is best for you.

To be on the safe side, you may just want to go with the 3000W so you never have to worry about having power on hand. You just need to pick the device that works for your power needs.

2000w vs 3000w Inverter


The obvious difference is their size. The 2000W is going to be smaller in power output as well as physical size. The next difference will be the number of loads that each can handle.

The 3000W is going to be able to power more loads than the 2000W and for a longer period of time. This may be the biggest difference you need to consider. Your electrical use will need to be factored in at this point to see if the 2000W can handle what you want to use and when you want to use it.

What helps make your decision easier is determining the maximum and continuous loads you will need to power. The size of the battery will only tell you how long the inverter will work before the battery runs out of power.

Even when you are not running a lot of power through the inverter, it is better to get the bigger size. Not only does the 3000W run quieter, but it is also nice to have the extra power available when you do decide to use it.

The 2000W may not be there with any power when that situation occurs. Where the 2000W edges out the 3000W are in the amount of current needed to run the devices. The latter device needs 500 ma more current to run on idle or when there is no load on the device.

According to some experts, this is not a big deal.

What Can a 2000-Watt Inverter Power?


It will run just about any electric device that does not require more than 2000 watts of power. This means that you may not be able to run more than a couple of electrical devices at the same time.

The following list will let you know how it can operate individually. Then you can do the math to see which items can be run at the same time:

Toaster – 1200 watts

TV – 250 watts

Computer – 150 watts

Lightbulb – 120 watt

Microwave – 1000 watts

Coffee maker – 1000 watts

Stereo – 300 watts

Ceiling fans – 140 watts

Electric heater – 1200 watts

Hairdryer – 1200 watt

Freezer – 600 watts

Dehumidifier – 800 watts

Laptop – 150 watt

Phones – 50 watts

Dishwasher – 1500 watt

Electric drills – 600 watt

8” circular saw – 1400 watt

Xbox, PlayStation – 40 watt

Blender – 480 watt

Iron – 1200 watt

Even if you get close to 2000 watts, you may want to rethink your operating strategy. You have to be careful of which items you will be able to run at the same time. For example, you won’t be able to run the hair dryer at the same time as the electric heater.

Nor can you run the microwave at the same time you are preparing your morning coffee. When you buy the 2000W you need to plan out your electrical device use and stick to it.

You also have to factor in start-up wattage to make sure you are covered when another device is turned on.

Why Would You Need a 3000-Watt Inverter?


As you can see by the above list, you need the 3000W inverter when you need to run more than one or two electrical devices at the same time. There are different sizes of inverters beyond the 2000W and the 3000W but the 3000W is the happy medium.

You will find that it supplies enough power to most trailers no matter which devices need to be plugged in. It is also the best choice as it does supply a lot of power when you need it.

For larger trailers and families, you may want to look at going larger than the 3000W as some of those models, etc., will take up a lot of power and even the 3000W can’t handle the demand.

Your situation will dictate what size you need but the key is not to go too small. When you go small, you won’t have that extra energy sitting there waiting to be used and that can cause some inconvenience for you.

What Will a 3000-Watt Power Inverter Run?


When you look at the above list, you will see that it can run every item on that list. Plus, it can run the combination of the higher wattage devices at the same time. You may not get 3 of them running but you can run 2 of them.

For example, you can run the microwave and the coffee maker at the same time. Just watch out for start-up wattage problems. It will handle just about any device needing electrical power including a chainsaw, table saw, and other power tools if you like being a handyman.

What the 3000W cannot handle will be very large electrical devices that have start-up watts registering over 3000 watts. What that means is that just about anything you have in your RV or travel trailer can be run by the 3000W inverter.

The key is to make sure you know all the wattage demands for start-up and run-time before you flip the switch on more than one item.

Tips For Using an Inverter

1. Inverters are best when you are setting up a solar panel system and running your RV or trailer on that power source. Since it is a renewable source, you can use the inverter just about anywhere.

2. Power inverters can also power cabins if you stay in one. They are not just for RVs and trailers. They are a very versatile piece of electrical equipment that can help you with your power needs in pop-up trailers as well.

3. You will find that many inverters have USB ports installed. This will enable you to recharge cell phones, laptops, etc., when you are far from a power grid.

4. The best inverters come with digital screens. That makes it easier to track your power usage as well as make sure everything is running smoothly and correctly. Those screens should also let you know the battery power supply levels as well.

5. Most new power inverters are made to be very quiet. That makes it easier to sleep through the night without using ear plugs. Check the decibel levels of each one before you buy your new model.

Some Final Words

Getting the right power inverter for your camping situation takes a little math. You need to figure out what devices you will be running, and what their wattage demand is and compare that with the inverter size.

Tobe on the safe side of electrical use, go with the 3000W. It may be more than what you need but there will be times when you may need more than what a 2000W can supply.

The price difference between the two is not that much either, so it pays to pay more for better service.
