Our quiet 4000-watt generator review looked at the top generators for you to consider. You'd be getting a quiet generator if its sound level in decibels lies between 60 and 69dB, the sound range of a normal conversation.

If it goes to 70dB, it's the level of sound you'd hear from a washing machine. That's practical as well because you'll not hear it from inside your home, and your neighbors won't either.

Nevertheless, if it's over 70dB, it's the same sound level as busy city traffic or a lawnmower. No one wants that.

The Champion Power Equipment 100302 we discussed earlier has a sound level of 64dB; hence, it's one of the best quiet 4000-watt generators.

Tips To Get You The Best Quiet 4000-Watt Generator

Sound is a priority for us in this article. That's why we've listed the best quiet generators. Now, how can you compare the ones above?

Do You Need One At Home, At Work, Or When Camping?

It matters because of the voltage plus the power outlets needed. If you need one to power your RV, the generator should be RV ready such as the Champion Power Equipment 100302 discussed in the section above.

It should also be portable, compact, and quiet to match the outdoor lifestyle of a camper. To power your home during emergencies, get a portable one with fuel that doesn't degrade fast. In contrast, you'd need a high power generator for home DIY projects or your workplace.

Power Needed

Some appliances have a startup power that's different from their power consumption. For example, a microwave has a startup power that's about two times its power consumption, while a PC has the same startup and power consumption.

Therefore, you can calculate the generator power needed by adding the startup power of all the appliances you'll use at once.

Another confusing area, following...

The Type Of Generator

You'll come across inverter and standard generators. On one end, the inverter gives you stable, high-quality power you can use on gadgets like a computer, though it attracts a high price.

Such a generator protects delicate components of electronic devices from a power surge, unlike the standard generator that provides a single-phase electric current.

The standard generator, however, is a simple design with moderate quality and an affordable price.

The Accessories

They'll make the generator more efficient. For example, the WEN GN400i in our review has a parallel-ready panel to use when connecting it to another WEN generator to double the power output. You may also need additional in-built features, such as a low oil shut-off.

Start Type

When there's a power outage at night, but you still want to watch television, you have to switch on your generator. If it has a recoil start, you have to walk outside to start it manually. Therefore, go for a generator with a wireless remote start instead of a manual start.

The Champion Power Equipment 100302 has two models, a manual and a remote start, while the Green-Power America GPD4000 has a manual start only.

The Runtime

It'll either be at 50% or 25% load on a full tank. The number of hours given as the runtime tells you the duration it'll run at half or a quarter of the load rating in watts. For example, if you have 8 hours of runtime at 50% load, it means the running time at 2000 watts.

The Fuel

Fuel will add to the cost of using and maintaining your generator. Consider the features and advantages of all fuel types. For example, propane gas is environmentally friendly, clean, and you can store it for a long time. However, it burns fast. You can obtain gasoline, but it's highly combustible.
