Buying Guide: How To Choose The Best 4000 Watt Generator That Suits Your Needs

Best 4000 Watt Generator

After reading our reviews, a minority of you here have already found the best 4000 watt generator for your needs, budget, and demands. Congratulations! We are happy to be a part of helping you find out the most suitable generator among many choices in the market. 

With many of you who haven’t found the perfect one, don’t worry! This is a normal situation. We understand that because we all have already been there before. What you have to do right now is to start reading our buying guide, to know and acknowledge some important criteria you need to take into consideration when deciding to buy a suitable generator. 

This is a crucial section so we highly recommend you pay attention to it and take notes!

Conventional Vs Inverter 

Best 4000 Watt Generator

There are 2 types of generators: a conventional generator and an inverter generator. Therefore, we want you to determine which type of generator you want to own? Every generator has its advantages and disadvantages.

With a conventional generator, it just generates AC electricity and releases it from the electrical outlet. In contrast, an inverter generator generates electricity in three steps (high power AC to DC and then return to steady, and clean AC power).

Moreover, when it comes to noise level, a conventional generator will be noisier than an inverter generator. Also, an inverter one is more fuel-efficient and more expensive than a conventional unit. However, a conventional generator will produce more power.

Single Vs Dual Fuel

Most people like the single fuel generator. A single fuel generator is a standard model that solely depends on one source of fuel, which is gasoline. 

However, a dual fuel generator can be a big help to you. With this kind of generator, you can rely on 2 types of fuel, which is gasoline and propane. 

Best 4000 Watt Generator

In our view, we think the dual fuel generator will be a better choice. Because of the availability of two types of fuel, it helps to guarantee that you will have electricity no matter what the circumstances are. If you depend on one form of fuel, you could be restricted to what you may have available at home.

Price

4000-watt generators can come from a variety of prices. A common point is that it will cost you several hundred dollars. However, you may find a generator at $200 or even up to $800 to $900. It all depends on your budget.

If you are tight on budget, you can choose a cheaper model. In contrast, if the budget is not your concern, you are free to go! Many models in the market for you to choose from.

However, you should choose the one with the suitable features and power ranges for your needs. We want to remind you that it’s better to pay more money for a sustainable generator to use for a long time than having to rebuy a new one after some years. 

Power Output

Best 4000 Watt Generator

A power output includes starting and running watts. When you mention the 4000-watt generator, it talks about the starting watts that use to start devices in the first few seconds. After that, the running watts come into effect. You need to remember that the running wattages (also known as rated wattages), will always be under 4000 watts. 

Therefore, when you use the generator for appliances like a TV, a coffee maker, an mp3 music player, or a computer, you can operate all these devices at the same time and there still will be some left electricity. 

However, if you intend to use for types of equipment like freezers, or refrigerators, or air conditioners, this is a whole different story. These appliances require a large amount of energy. Therefore, before using, you need to list all these items you want to generate and add their watts to make sure it doesn’t exceed 4000 watts.

Fuel Tank Size

For your information, the amount of time to run relies deeply on the fuel tank size. For instance, a generator with a fuel tank size of 4.5 gallons will offer you more runtime than a fuel tank size of 3 gallons. 

A smaller fuel tank will reduce the size of a generator, therefore, requires you to replenish the tank regularly.

Best 4000 Watt Generator

In contrast, a bigger fuel tank will help you lengthen the runtime, however, it depends on the fuel-efficiency of the generator as well. And of course, it will increase the size of the generator. 

Power Outlets

Remember to check the number and kinds of outlets that are available in the generator to decide if it’s suitable for your use. 

You can choose 2 common 120V outputs for ordinary use. If you want to charge electricity for multiple devices, you can choose 4 to 6 outputs

Moreover, if your intent is for high-powered devices, ensure to look at the twist look receptacles to avoid the easy disconnection of the plugs in rough environments. 

Also, if you want to charge devices for your RV, remember to check if a generator comes with the RV outputs. 

Finally, the USB outlets should also be included for your convenience. 

Noise Level

Best 4000 Watt Generator

This is also an important factor you need to look at when considering a generator. This is especially necessary if you want to bring it to your camping or in your recreational vehicle. 

With a loud noise generator, you will wake your partners, your families, and your neighbors. Therefore, this will cause discomfort for these people and produce complaints. We are sure that you don’t want this to happen

Therefore, make sure to look at the noise level in the product’s description. A generator with smaller engines will produce less noise than the bigger engines. However, it also depends on the noise reduction system of a generator. So choose wisely!

Portability

Best 4000 Watt Generator

This depends solely on your purposes. If you plan to use it at home, at an only place, then the compact design is not your top-priority aspect. On the other hand, if you want to bring it with you, we suggest you choose the portable one to avoid the inconvenience you may face when transporting a heavy one. 

Luckily, most of the 4000 watt generators are simple to carry around. Then we can say that you don’t have to worry much about their size and weight anymore!

Warranty

Not just generators, with every electronic appliance, you need to take a serious look at the warranty. You probably don’t want to deal with the situation where your equipment is broken and you have to prepare for a high chance that you may have to buy a new one due to the lack of warranty. 

With generators, a 1-year warranty is a required factor. If possible, a 2 or 3-year warranty will be much better.
