What matters most
Running watts matter more than peak watts Every generator lists two numbers. Peak or starting watts describe a brief surge for motor startup, while running watts describe what the unit sustains. Size your purchase on running watts, then confirm the peak figure covers your largest motor load, typically a refrigerator compressor, well pump or air conditioner. A fridge that runs at 700 watts can spike above 2000 for a second, and that spike is what trips undersized units.
Inverter versus conventional Inverter generators produce clean, stable power suitable for laptops, televisions and medical equipment, and they throttle down when demand drops, which makes them quiet and fuel efficient. Conventional open frame generators run at a fixed engine speed, are louder and produce dirtier power, but they deliver far more watts for the money. For sensitive electronics choose inverter, for high capacity backup choose conventional or a large inverter.
Fuel choice and storage reality Gasoline offers the highest output but degrades in storage and needs stabiliser plus periodic carburettor attention. Propane stores indefinitely, starts cleanly in cold weather and leaves the engine cleaner, at the cost of roughly ten percent less output. Dual fuel models let you keep propane on hand for readiness and switch to gasoline when you need maximum capacity.
Connection, safety and placement Never backfeed a generator through a dryer outlet. A properly installed transfer switch or interlock kit is the only safe way to power house circuits, and it protects utility crews from backfed voltage. Run any fuel burning generator outdoors, well away from windows and vents, because carbon monoxide is the leading cause of generator deaths. Look for models with a CO shutoff sensor.
Frequently asked questions
How many watts do I need for a home outage?
For a fridge, lights, phone charging and a few small devices, 2000 to 3500 running watts is usually enough. Adding a well pump, furnace blower or central air pushes you toward 7500 watts or more, and that is where transfer switch capable models make sense.
Can I run a generator in my garage with the door open?
No. An open garage door does not prevent carbon monoxide from building up. Generators must run fully outdoors, at least 20 feet from the house, with the exhaust pointed away from doors, windows and vents.
Is an inverter generator worth the extra cost?
If you are powering computers, televisions, variable speed appliances or medical equipment, yes, because the clean sine wave output avoids damage and interference. If you are only running lights, heaters and older tools, a conventional model gives more watts for the money.
How long can a portable generator run continuously?
Most manufacturers recommend shutting down for cooling and oil checks roughly every 24 hours, and runtime per tank ranges from about 8 to 18 hours depending on load. Propane models can run longer if you swap cylinders using a changeover valve.
What is a transfer switch and do I need one?
A transfer switch isolates your home from the utility grid and lets the generator power selected circuits safely. It is required by electrical code for any permanent connection to house wiring, and it should be installed by a licensed electrician.
Will a generator start my RV air conditioner?
A 13,500 BTU rooftop unit typically needs around 3000 starting watts, which rules out most 2000 watt inverters unless you add a soft start kit or run two units in parallel. A 3500 to 4500 watt inverter handles it comfortably.
How should I store a generator between outages?
Run the carburettor dry or use stabilised fuel, change the oil before storage, and start the unit for a few minutes every month or two. Owners report that stale fuel in the carburettor is by far the most common reason a generator will not start when needed.
Can two generators be connected together?
Many inverter models support parallel operation with a manufacturer kit, which combines two units into roughly double the output. This is often lighter and quieter than one large generator, and it lets you run just one unit for small loads.
The bottom line
The Honda EU2200i is the safest pick when quiet, dependable power for electronics matters most, and the Westinghouse iGen4500 is the RV answer thanks to its 30 amp outlet and air conditioner headroom. If you want a generator that keeps a house running through a multi day outage, the DuroMax XP13000EH paired with a professionally installed transfer switch is the practical choice.
