Your Generator Needs

To determine whether a generator is appropriate for your needs, you need to first add up the wattage of tools, appliances, and motors you want to run at the same time. Then select a generator with the running wattage rating to match or exceed the total load.

Keep in mind that tools and appliances with electric motors require additional surge wattage at startup that can be double or triple the normal running wattage requirement. Look at the surge watts required and make sure you choose a generator with enough additional wattage to start them. (And remember that you're typically not starting more than half of the items at the same time.)

Here's a sampling of power ratings for common household appliances.

4.0 out of 5 stars Cost-effective Emergency Power, August 30, 2011

This review is from: DuroStar DS4000S 4,000 Watt 7.0 HP OHV 4-Cycle Gas Powered Portable Generator (Lawn & Patio)
I bought this generator in preparation for hurricane Irene. Ordered it on Wen., it arrived on Fri., just in time to set it up before the storm (can't beat Amazon Prime!). The generator was easy to set up and started in one pull. This generator provided power sufficient to run the refrigerator, a mini-split a/c unit, TV, and a couple of fluorescent lights for two days. Under this load, a full tank (4 gallons) lasted around 12-14 hours. This unit appears to be a Chinese import so I do have my doubts about long-term reliability, never the less, the DS4000 appears surprisingly well-constructed and capable for the price.

Pros:
Inexpensive
Easy to Operate
Relatively Quiet (compared to a 22" lawn mower)
Compact
Easy to read fuel gauge

Cons:
Recommended oil change interval of 20 hours (change the oil every other time you fill the gas tank?)
Oil drain obscured by frame below (as oil drains it runs along the frame and makes a mess)... Read more

This review is from: DuroStar DS4000S 4,000 Watt 7.0 HP OHV 4-Cycle Gas Powered Portable Generator (Lawn & Patio)
We have used over the last 3 days to power fridge, 2 fans, charge mobile phones and laptops and run a few lights. We are getting approx a run time of just over 13 hours on one tank (4 gallon) of gas.

Last night even hooked up the tv and cable so our son could watch some tv. Nick, Nick, Nick, Nickeloden. :)

This morning it powered the coffee maker and iron so we could be awake and wrinkle free.

I really did not expect the generator to run as long as it did on one tank so very happy with the purchase.

Next thing to purchase is something to cover it in case of heavy rain. Setup a tarp over table with bungee cords last night but would like something quicker to setup.

If we continue to have the power outage problem here in Oak Park we may look into the natural gas generator that hooks into electric system and fails over automatically. As always we will try to get it from Amazon our favorite store.

4.0 out of 5 stars Appears to handle the task, April 5, 2011
This review is from: DuroStar DS4000S 4,000 Watt 7.0 HP OHV 4-Cycle Gas Powered Portable Generator (Lawn & Patio)
I purchased this generator through an on line auction. After filling with oil and gasoline it started on the second pull. I also purchased a transfer switch to control six circuits (Reliance Model# 31406crk). The generator provides enough power to run my furnace, two refrigerators, a small freezer and some house lights. I would also recommend purchase of the wheel kit. I have only used this generator in a test situation. I don't know how well it will perform for an extended period or if the noise level will become annoying after an extended time.
