Best Portable Generators for Emergencies (2026)

When the power goes out, a generator is the difference between riding out a disaster comfortably and sitting in the dark hoping the lights come back. According to the EIA, the average American experienced over 7 hours of power interruptions in 2022, and that number is trending up. A portable generator keeps your refrigerator cold, your medical devices running, and your family safe. Here is how to pick the right one.

Gas vs. Dual-Fuel vs. Inverter: Which Type Do You Need?

Conventional Gas Generators

Traditional open-frame generators run on gasoline and produce raw, high-wattage power. They are the most affordable option per watt and the best choice if you need to run heavy loads like a well pump, central AC, or multiple large appliances simultaneously.

The downside: they are loud (65 to 80 dB), heavy (100 to 250+ lbs), and produce "dirty" power with more voltage fluctuation. That last point matters if you are powering sensitive electronics. They also require you to stockpile gasoline, which has a shelf life of 3 to 6 months without stabilizer.

Dual-Fuel Generators

Dual-fuel generators run on both gasoline and propane. This is a significant advantage in emergencies because gas stations run dry fast after a disaster, but propane stores indefinitely and is widely available. You lose about 10% to 15% power output on propane compared to gasoline, but the fuel flexibility is worth it.

Inverter Generators

Inverter generators produce clean, stable power safe for laptops, phones, and medical equipment. They are significantly quieter (50 to 60 dB) and more fuel-efficient because the engine speed adjusts to the load. The trade-off is lower wattage (usually 1,000 to 4,500 watts) and higher cost per watt.

For most households, an inverter generator is best for everyday outages while a larger conventional or dual-fuel unit is better for extended disaster scenarios.

How Much Wattage Do You Need?

This is where most people make mistakes. They either buy too small and trip the breaker constantly, or way too large and waste money and fuel. Here is a quick reference:

• Essentials only (lights, phone charging, fans): 2,000 to 3,000 watts
• Essentials + refrigerator + sump pump: 3,500 to 5,000 watts
• Full home backup (AC, well pump, multiple appliances): 7,500 to 12,000+ watts

Pay attention to both running watts and starting watts. Motors in refrigerators, pumps, and AC units surge to 2 to 3 times their running wattage for a few seconds at startup. Your generator needs to handle those surges or it will shut down.

Our Top Picks

Best Overall: DuroMax XP13000HX

The DuroMax XP13000HX is a beast. 13,000 peak watts, 10,500 running watts, dual-fuel capability, and electric start. It produces enough power to run essential home circuits through a transfer switch, including a refrigerator, lights, fans, a sump pump, and even a window AC unit simultaneously.

The 500cc OHV engine runs up to 8.5 hours on a full tank of gasoline at 50% load. On propane, expect about 6.5 hours. It includes a CO Alert sensor that shuts the unit down if carbon monoxide levels get dangerous, which is a feature that saves lives every hurricane season.

Best Inverter: Honda EU2200i

The Honda EU2200i is the gold standard for inverter generators. It produces 2,200 starting watts and 1,800 running watts of clean, stable power. At 48.5 lbs, one person can carry it. At 48 to 57 dB, you can have a conversation next to it. And Honda's reliability is legendary: these engines run for thousands of hours with basic maintenance.

The EU2200i will not power your whole house. But it will run a refrigerator, charge devices, power lights, and keep a CPAP machine going all night. For most short-term outages, that is exactly what you need. You can also parallel two units together for 4,400 watts if you need more capacity later.

Best Value: Westinghouse WGen5300v

Westinghouse consistently delivers solid generators at fair prices, and the WGen5300v is their best value offering. 6,600 peak watts and 5,300 running watts for under $500 (often on sale). That is enough to run a refrigerator, freezer, sump pump, lights, and several outlets simultaneously.

It runs on gasoline only, but at this price point, that is a reasonable trade-off. The 6.6-gallon tank provides up to 13.5 hours of runtime at 25% load. It also comes with a remote start key fob, which is a nice convenience feature at this price.

Best for Apartments: Champion 2000-Watt Inverter

If you live in an apartment, condo, or townhouse, you need something small, quiet, and easy to store. The Champion 2000-watt inverter generator checks all three boxes. At 39 lbs and 53 dB, it is lighter than a bag of dog food and quieter than a normal conversation.

It will not run a refrigerator and a microwave at the same time, but it will keep your phone charged, power a fan, run a lamp, and keep a small fridge going. For apartment dwellers who just need the basics during a blackout, this is the right size. It is also parallel-capable if you want to double up later.

Critical Safety Rules

Generators kill people every year. Not from the machine itself, but from carbon monoxide poisoning and electrocution. These rules are non-negotiable:

• Never run a generator indoors. Not in a garage, not in a basement, not in a carport. Carbon monoxide is odorless and kills within minutes. Place the generator at least 20 feet from any door, window, or vent.
• Never backfeed your electrical panel. Plugging a generator directly into a wall outlet without a transfer switch can electrocute utility workers repairing power lines. Always use a transfer switch installed by a licensed electrician, or run extension cords directly from the generator.
• Let it cool before refueling. Gasoline + hot engine = fire. Shut down the generator and let it cool for at least 5 minutes before adding fuel.
• Use heavy-duty extension cords. Undersized cords overheat and cause fires. Use 10-gauge cords for long runs and 12-gauge for shorter ones. Never daisy-chain multiple cords together.
• Ground the generator per manufacturer instructions, especially if using a transfer switch.

Fuel Storage

Your generator is useless without fuel. Here is how to keep a reliable supply:

• Gasoline: Store in approved containers (red cans with spark-arresting spouts). Add fuel stabilizer (like STA-BIL) to extend shelf life to 12 to 24 months. Rotate stock by using it in your car or lawn mower. Keep 10 to 20 gallons on hand for a multi-day outage.
• Propane: Stores indefinitely in sealed tanks. Standard 20-lb BBQ tanks work fine with dual-fuel generators. Keep 2 to 3 tanks full. No stabilizer needed, no degradation over time.
• Store fuel outdoors in a shed or ventilated area away from living spaces and ignition sources.

Transfer Switch: Worth the Investment

A manual transfer switch lets you safely connect a generator to your home's electrical panel. An electrician installs it next to your breaker box, and when the power goes out, you flip the switch to generator power. No extension cords running through windows. No risk of backfeeding the grid.

A basic 6 to 10 circuit manual transfer switch costs $200 to $400 for the unit plus $500 to $1,000 for professional installation. If you own your home and plan to use a generator for emergency backup, this is the best $1,000 you will spend on preparedness. It turns a portable generator from a convenience into a genuine home backup system.

The Bottom Line

For whole-home emergency backup, the DuroMax XP13000HX gives you the power and fuel flexibility to handle extended outages. For quiet, portable power during shorter blackouts, the Honda EU2200i is unmatched in reliability and quality. The Westinghouse WGen5300v hits the sweet spot of power and price for most households. And the Champion 2000-watt inverter is perfect for apartments and minimal setups. Buy one, learn how to use it safely before you need it, and keep fuel on hand. When the next outage hits, you will be the house on the block with the lights still on.
