Why Portable Generators Aren’t the Safe or Smart Choice for Home Backup Power

Written by Brad Nash | Jan 4, 2025 3:15:00 PM

When the power goes out, it’s tempting to think a small, portable generator will do the trick. They're inexpensive, easy to buy at your local hardware store, and seem like a quick fix. But while they might power a few appliances in a pinch, portable generators fall far short when it comes to protecting your home, your safety, and your long-term peace of mind.

At Guardian Home Generators, we specialize in whole home backup systems because we know what's truly required to keep your household running reliably. In this blog, we break down the risks and limitations of portable generators—and why they’re not worth the gamble.

1. Portable Generators Can Be Dangerous

Perhaps the biggest concern with portable generators is safety. These machines are notorious for causing carbon monoxide (CO) poisoning, fires, and electrocution if not used perfectly.

  • Carbon Monoxide Risk: Portable generators emit deadly CO gas. If used too close to the home—or worse, inside a garage or enclosed space—fumes can build up quickly, causing serious illness or death.
  • Fire Hazards: Improper fuel storage and overloading circuits can lead to electrical fires.
  • Shock and Electrocution: In wet conditions or without proper grounding, portable generators pose a real electrocution risk.
  • WARNING:  NEVER run a portable generator near your home and absolutely never in a garage.  Portable generators must be a MINIMUM of 20 feet from your home.

Whole home generators, on the other hand, are professionally installed, code-compliant, and fully enclosed, significantly reducing all of these risks.

2. They Don’t Power Your Whole Home

Portable generators typically produce between 3,000–8,000 watts—enough to power a few lights and appliances. But they can’t handle your HVAC system, electric water heater, oven, or other critical home systems. That means during a major outage, your comfort and safety are still at risk.

With a properly sized backup generator from Guardian, your entire home stays operational—including heating, cooling, medical devices, Wi-Fi, refrigerators, and more.

3. Manual Setup During an Emergency

Portable generators require manual setup every time the power goes out. That means:

  • Pulling the generator out of storage
  • Refueling it (often in the rain or dark)
  • Running extension cords through windows or doors
  • Monitoring fuel levels and engine operation

This isn’t just inconvenient—it’s dangerous during storms, hurricanes, or freezing temperatures. By contrast, Guardian’s whole home systems switch on automatically within seconds of an outage, keeping you protected without lifting a finger.

4. They Rely on Gasoline, Which May Not Be Available

Most portable generators run on gasoline—which becomes scarce during emergencies. Long lines at gas stations (or stations without power to pump fuel) can leave you stranded. Our whole home generators run on natural gas or propane, which are either piped in or stored on-site, offering greater energy security.

5. Short Lifespan and High Maintenance

Portable generators are not built for long runtimes or repeated use. They often require frequent oil changes, struggle under load, and wear down quickly. In contrast, Guardian’s standby generators are engineered for durability—with routine maintenance and long-term reliability built in.
