How much power does the A-iPower SUA4300iD give you?
On gas, this model is rated for 3,450 running watts and 4,300 starting watts. Running watts are the power available while your appliances are on. Starting watts are a short burst to help things like refrigerators and pumps turn on. You cannot use that bigger number for appliances that need steady power.
On propane, you get 3,100 running watts. That is 350 fewer watts than on gas.
| Fuel | Running watts | Starting watts |
|---|---|---|
| Gasoline | 3,450 W | 4,300 W |
| Propane | 3,100 W | 3,900 W |
The details for this model
Model: SUA4300iD. Manufacturer part number: SUA4300iD. These are published specifications, not results from our own testing. If a detail is missing, we leave it marked rather than use a number from a similar generator.
A detail to confirm: The headline gives 4,300W gas / 3,900W LPG starting output but its table reverses those peak figures. Noise is also described as both 52 and 62 dB. We use the headline wattages and the qualified 62 dBA at half power / 7m figure, pending manufacturer clarification.

A 120V outlet powers ordinary household plug-in devices. Some pumps and larger equipment need 240V. Inverter models use electronics to control the electricity they supply. THD measures how smooth that electricity is; a lower number generally means smoother power. Check your device instructions before connecting electronics.

How long will it run?
The published runtime is 7.5 hours at 25% gasoline power use. The listed gas tank holds 1.6 gal. The more power you use, the sooner you will need fuel. A runtime measured at 25% load means the generator was only supplying a quarter of its running power, not working flat out.
Propane gives you another fuel option. Follow the manual for the regulator and cylinder size. A small cylinder may not supply enough fuel in cold weather. Read our fuel-storage guide →
What can you run during an outage?
Start by listing the appliances you need most. Check both their running watts and the extra power they need to start. A refrigerator, for example, may need much more power for a moment when its compressor kicks on.
Here is an example, not a test of this generator: a refrigerator using 600 running watts, plus 100 watts of lights and 100 watts for a router and other small devices, adds up to 800 watts. If that refrigerator needs 1,800 watts to start, the total briefly reaches 2,000 watts. Your appliances may use different amounts.
That example is within the listed gasoline running and starting ratings. You still need to check your own refrigerator, each outlet’s limit, and anything else that may turn on at the same time. If you use propane or natural gas, check those ratings separately.
A 1,500-watt heater uses a lot of power on its own. Follow its connection instructions; many portable heaters must plug directly into a suitable wall outlet. This review does not confirm 240V output for this model. Do not choose it for a 240V pump or air conditioner without checking that first. Work out how much power you need →

Reasons to consider it
- Runs on gas or propane.
- 3,450 running watts on gas.
- Inverter design, which can be useful for compatible electronics.
Things to keep in mind
- It weighs 54.8 lbs / 24.8 kg. Make sure you can move and store it.
- Switching to propane reduces running power to 3,100 watts.
- Noise figures depend on the distance and how hard the generator is working.
What owners are saying
We do not have enough owner feedback for this exact model to give a fair summary. Reviews for a similar generator, or another option on the same Amazon page, may describe a different machine. Before buying, check recent reviews for the full model number and find out how the seller handles service and returns.
Starting, moving, and maintenance
The listed starting options are: pull cord start. Practice starting it before an outage so you know you can use it when needed. It weighs 54.8 lbs / 24.8 kg. Wheels can help on level ground, but they do not make stairs or lifting into a vehicle easy.
The listed warranty is 3 Year. Read the full terms, including whether your seller and intended use are covered. Follow the manual for oil type, oil changes, and storage. Keep track of running hours during a long outage. See our maintenance guide →

Questions about the A-iPower SUA4300iD
How much running power does it provide?
3,450 watts on gasoline; 3,100 watts on propane. Starting watts are only available briefly, not for steady use.
Is it an inverter generator?
Yes, this model is listed as an inverter generator. Its published power-distortion figure (THD) is < 3%. Check your electronics’ power requirements before connecting them.
Can I use it in a garage if it has CO shutdown?
No. Never run a generator in a garage, even with the door open. Use it outdoors at least 20 feet from homes and openings, with exhaust pointed away. Carbon monoxide shutdown is extra protection; it does not make indoor use safe.
Can I connect it to my house?
Check the voltage and outlets before planning a home connection. Have an electrician choose and install the right transfer equipment and check the generator’s wiring setup. Never connect a generator to a household wall outlet.
Should you consider the A-iPower SUA4300iD?
This small dual-fuel inverter has wheels, a handle, and automatic fuel switching. It is better suited to selected 120V appliances than a whole house. The manufacturer's page gives conflicting starting-watt and noise figures, so check those details before buying.
