Best Mid Size 3000 Watt, 3500 Watt and 4000 Watt Generator For Most People’s Needs

On this page we’ll take a look at the best mid size conventional generator for most people. Mid size is anything between 2 kW and 5 kW by our definition. 3000 Watt, 3500 Watt and 4000 Watt generators are the most popular of all the generators on the market. They offer good amount of power at an affordable price.

Mid-size Gensets CTADo you want enough power for your entire house?

Do you want a portable generator you can chuck in the back of your truck and take camping?

If you answered yes to either of those you’re in the wrong place.

A mid-size generator sits between highly-portable and huge-power.

You know how at the movies you tend to buy the mid-size popcorn? The small is not enough and you doubt you can finish the large… Yeah, the mid-size generator hits the sweet spot too. It’s the most popular size of generator on the market for this reason.

How do people use this size?

In February I went to this Greek Festival at the local park. There was tons of food trucks serving Greek food and beer. And there was live music and that sort of thing.

Because I love generators I was walking around the back side of all the food stalls. Why? Because I was checking out the generators they were using to power their fridges.

Some had Yamaha inverter generators connected in parallel (2x 2,400 watts). Some had extension cords connected to larger generators that were located further from crowd. But most had clearly rented portable generators from the local generator hire company. All these rentals were 4,400 surge watts and 3,500 running watts – enough to power a few fans and their fridge and freezer for the day.

What Else Can a Mid Size Portable Generator Power?

Let’s take a 3,500 watt portable generator and see what combination of electrical devices can be powered from it at once:

Combo 1: Washing machine, toaster, dishwasher, TV, fan and light

Combo 2: Oven, coffee maker, fan and light

Combo 3: Small air conditioner, blow dryer, TV, desktop computer and wifi modem

All those combos add up to around 3,500 running watts. Most portable generators in this range will power half that load for 7-9 hours on one tank of gas.

What will you need to power? Here’s some people using their mid-size generators in the wild:

Also Good: Champion 3,500 Running Watts

Champion Power Equipment 46539 4kW Portable GeneratorAnother great 3500 running watts option comes from this California company – Champion Power Equipment.

It is more than the DuroMax and similar quality, and that is why it takes a close second instead of first place honors.

Champion has sold millions of portable generators since its 2003 founding, and are a trusted and sought after brand. Both of these machines are great options in the 3500 running watts category. The reason to get the Champion over the DuroMax is it has longer runtime. It can go for 3-4 hours longer than the DuroMax off the same amount of fuel.
