Starting Watts vs Running Watts: Get the Math Right

Every generator wears two numbers, and confusing them is the most common buying mistake. Running watts is what the unit sustains continuously; starting watts is the brief surge it can supply when a motor spins up. A refrigerator that runs at 200W may demand 1,200W for a second at startup, and a window AC can triple its rated draw. Add up the running watts of everything you will power simultaneously, then identify the single largest surge item and make sure the generator covers running total plus that surge. For most homes, 5,000 to 7,500 running watts hits the sweet spot, covering a fridge, furnace fan, sump pump, lights, and electronics with room to spare.

Open-Frame vs Inverter: Which Style Fits Your Life?

Open-frame conventional generators give you the most watts per dollar and shrug off dusty job sites, but they run loud, around 70 to 76 dB, and their raw output can be rough on sensitive electronics. Inverter generators convert power twice and deliver a clean sine wave with under 3 percent total harmonic distortion, safe for laptops, TVs, and modern furnace control boards. They also throttle the engine to match the load, cutting noise to the high 50s dB and stretching fuel. If your generator will live behind a house in a neighborhood, the inverter premium is worth every penny; if it powers saws on a rural site, open-frame value wins.

Carbon Monoxide Safety Is Non-Negotiable

Never run any gas generator indoors, in a garage, or near an open window, period. Carbon monoxide is odorless and can incapacitate a person in minutes. The best 2026 models include an automatic CO shutoff sensor, marketed under names like CO-Minder, CO Shield, or CO Sense, which kills the engine if exhaust accumulates around the unit. Place the generator at least 20 feet from the house with the exhaust pointed away from doors and windows, and install battery-powered CO alarms inside on every level. If you plan to backfeed circuits, do it only through a properly installed transfer switch or interlock, never a double-male cord, which can electrocute utility line workers.

Fuel, Runtime, and Features Worth Paying For

Runtime at 25 or 50 percent load tells you how a generator behaves in the real world. A good 7,000W unit should run 10 or more hours on its tank at half load, enough to sleep through the night. Electric start with a backup recoil cord saves your shoulder in cold weather, and a fuel gauge plus low-oil shutoff should be considered mandatory. Wheel kits matter more than people expect, because a 200-pound frame without wheels is a two-person job. Outlets should include a 30-amp twist-lock (L14-30R) if you ever intend to connect to a transfer switch, and GFCI-protected 120V duplexes are a welcome safety layer for outdoor cords.

Frequently Asked Questions

What size generator do I need for a whole house?

Powering an average whole house, including central air, usually requires 10,000 watts or more. Most families do fine with 6,500 to 8,000 watts covering essentials through a transfer switch instead.

How far from the house should a portable generator run?

Keep it at least 20 feet away with exhaust facing away from windows, doors, and vents. Pair that distance with indoor carbon monoxide alarms for layered protection.

Can a portable generator run in the rain?

Not uncovered. Water and electricity are a dangerous mix, and wet outlets can short. Use a purpose-made generator canopy or ventilated enclosure that keeps rain off while allowing airflow.
