How Much Can You Really Run On A Portable Generator?

A real world load test from South Florida that might surprise you.

If you have ever stood in front of a generator at Home Depot wondering whether it would actually keep your home running during a South Florida storm, you are not alone. The wattage numbers on the box can feel abstract. So we decided to put one to the test in a real home and document exactly what happened.

The Setup

A customer of ours here in South Florida had recently purchased a DuroMax 13,000 watt portable generator, one of the more capable units on the consumer market. It delivers up to 50 amps of power, which on paper sounds like plenty. But paper and reality do not always agree.

We connected the generator to the home using a proper transfer switch setup and ran a real world load test to see exactly how much amperage the home was drawing under normal daily conditions.

What Was Running During the Test

Here is what was running in the home simultaneously during the test:

✅ Central AC ✅ Refrigerator ✅ Ceiling fans ✅ Lighting throughout the house ✅ Microwave ✅ Entertainment system ✅ Wi-Fi router ✅ Washing machine

All of that running at the same time drew only about 13 amps. That is barely a quarter of what the generator can deliver.

When the electric dryer turned on it briefly spiked to 35 amps, still well within the generator's 50 amp capacity. And with the dryer off there was still enough headroom remaining to also run a standard water heater.

What This Tells Us

The results were genuinely eye opening. Eight appliances running simultaneously including central air conditioning and the home was only drawing 13 amps. Even at the peak spike with the dryer running the generator handled it without issue and still had 15 amps of capacity to spare.

This is partly due to how energy efficient modern appliances have become. A newer central AC unit running in a well insulated home draws far less than most people assume, especially once it has reached the target temperature and is simply maintaining it.

With the dryer off there was still enough capacity remaining to run a standard water heater. That is a genuinely comfortable home during an outage, not a stripped down survival situation.

The Key Factor Most People Miss

The generator's raw wattage is only half the equation. How it is connected to your home matters just as much.

A proper transfer switch or interlock kit is what allows you to safely and legally power your home's circuits from a generator. Without one you are either running extension cords through your house or risking backfeeding power into the utility lines outside. Backfeeding creates an energized line that utility workers restoring power in your neighborhood have no way of detecting. Linemen have been electrocuted and killed as a result. It is also illegal under the National Electrical Code.

Transfer Switch vs. Interlock Kit

A transfer switch is a dedicated panel that isolates your home from the utility grid and allows the generator to power selected circuits. An interlock kit is a more affordable option installed directly on your existing electrical panel that mechanically prevents your main breaker and generator breaker from being on at the same time. Both are code-compliant solutions when professionally installed. An interlock kit also allows the capability to run every circuit in your home from your portable generator by manually controlling your individual breakers.

The right choice depends on your home's electrical setup and how you plan to use your generator. During a consultation we will walk you through both options and give you an honest recommendation.

Sizing Your Generator Correctly

For most South Florida homes a 10,000 to 13,000 watt generator will cover the essentials very comfortably including AC, refrigerator, lighting, and everyday appliances. If you want to run an electric dryer or electric water heater simultaneously with everything else, being strategic about when you run high draw appliances is important unless you are at the higher end of that wattage range.

For homeowners who want to power true essentials only, a generator in the 5,500 to 8,500 watt range connected through a proper interlock kit can comfortably handle a refrigerator and freezer, lights and outlets, Wi-Fi and phone chargers, fans, and a smaller central AC or window unit. That covers the basics for most households at a very manageable cost.

Here are a few tips for getting the most out of your generator during an outage:

⚡ Start your AC first before adding other loads to allow the compressor to start without competing for power ⚡ Avoid running the electric dryer and microwave at the same time if your generator is on the smaller side ✅ A gas water heater is a major advantage during an outage since it draws virtually no amperage ✅ LED lighting throughout your home dramatically reduces your overall electrical load ⚡ Always have a licensed electrician connect your generator safely with a proper interlock kit or transfer switch

Hurricane Season in South Florida

If you live in Broward or Palm Beach County backup power is not a luxury. It is a necessity. South Florida averages multiple named storms per season and even a near miss can knock out power for days. Having a properly connected generator means your food stays cold, your home stays cool, and your family stays safe and comfortable no matter what the season brings.

We regularly help homeowners throughout Fort Lauderdale, Davie, Hollywood, Pembroke Pines, Pompano Beach and Broward and Palm Beach Counties install transfer switches, run dedicated generator circuits, and ensure everything is up to code before storm season hits. Do not wait until a storm is named to start thinking about this.

Bottom Line

A quality 13,000 watt portable generator connected properly with a transfer switch or interlock kit can keep a South Florida home running very comfortably during an outage. Our real world load test proved it. With the right setup you are not choosing between your AC and your refrigerator. You are running both, along with everything else that matters.

If you have questions about generator connections, interlock kits, transfer switches, or getting your home ready for storm season we are here to help.
