A-iPower AiPower GXS1500i 1500-Watt Gasoline Portable Inverter…

What it can run

Generators are sized in watts. Running watts are what the unit can supply continuously; starting watts are a short surge for motors and compressors. The A-iPower AiPower GXS1500i 1500-Watt Gasoline Portable Inverter Generator is rated at 1,200 W running and 1,500 W starting.

Wattstanding calculationWattstanding calculation — to size a generator, add the running watts of everything you will run at once, then add the largest single starting surge (starting − running watts) from any one motor. The result must stay within the generator's running and starting watts. Appliance wattages are typical planning values — read the nameplate.

Use the load calculator to total your own appliances.

Fuel and runtime

The maker states a 0.7-gallon tank and up to 8 hours at the stated load, which implies about 0.09 gallons per hour at that load.

Wattstanding calculation0.7 gal ÷ 8 h = 0.09 gal/h; a full day at that load ≈ 2 gal. Multiply by today's fuel price for a daily cost, or use the fuel calculator.

Seller or manufacturer claimUp to 8 hours at 25% load; up to 6 hours at 50% load

Connecting it to a home

To power home circuits you need a rated transfer switch or interlock and an inlet, matched to this generator's outlet and amperage, installed by a licensed electrician.

Seller or manufacturer claimOutlets as listed: 1 x 5-20R duplex, 20A, 120V

Check the pairing in the generator ↔ transfer-switch compatibility matrix.

SafetyNever plug a generator or battery system into a wall outlet to power the house ("backfeeding"): it can send electricity back into the utility lines and injure line workers, and it can start fires. Connecting a generator to a home's wiring is a job for a licensed electrician, with the permit and inspection your local code requires. Wattstanding does not give wiring instructions.

Safety and placement

SafetyNever run a generator inside a home, garage, basement or any enclosed or partly enclosed space — exhaust contains carbon monoxide, which can kill in minutes. Keep it outdoors, well away from doors, windows and vents, with the exhaust pointed away from the house, and use battery-powered carbon monoxide alarms indoors. Follow the maker's manual and U.S. Consumer Product Safety Commission guidance.

This listing mentions a carbon monoxide shutoff or sensor, which is a useful backup — not a substitute for placing the generator outdoors and keeping working CO alarms inside.
