How much power does the LIFAN LF4800iE-Y001 give you?
On gas, this model is rated for 3,800 running watts and 4,800 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 3,400 running watts. That is 400 fewer watts than on gas.
| Fuel | Running watts | Starting watts |
|---|---|---|
| Gasoline | 3,800 W | 4,800 W |
| Propane | 3,400 W | 4,300 W |
Some numbers come from the seller's listing and have not been confirmed in a matching manufacturer manual. Get those details before depending on this generator for important appliances.
The details for this model
Model: LF4800iE-Y001. Manufacturer part number: LF4800iE-Y001. 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: A matching primary manual was not retrieved. Do not borrow specifications from the gasoline-only LF4800iE.

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?
We have not confirmed a runtime figure that says how much power was being used. 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.
Confirm this generator’s running and starting ratings before using that example to choose appliances. 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 →
What we like and what to consider
Reasons to consider it
- Runs on gas or propane.
- 3,800 running watts on gas advertised by the seller; not yet confirmed in the correct manual.
- Inverter design, which can be useful for compatible electronics.
Things to keep in mind
- Confirm its weight before planning how to move it.
- Switching to propane reduces running power to 3,400 watts.
- There is no complete noise test to compare with other models.
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
Ask for the manual to confirm how this model starts. Practice starting it before an outage so you know you can use it when needed. Check its weight and size before deciding where to store it.
We have not confirmed the warranty for this exact model. 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 →
Other generators to compare
WEN DF475T →
The DF475T offers gas, propane, electric starting, and 120/240V output. It provides 3,800 running watts on gas. The larger 4,750-watt number is only for the brief extra power appliances need when starting.

WEN DF480iX →
The DF480iX gives you gas and propane, electric starting, wheels, and 4,000 running watts on gas. It is a 120V generator, unlike the 240V-capable DF680iX. It may suit appliance cords or an RV, but it cannot run a 240V well pump.

Westinghouse WGen3600cv →
This gas generator provides 3,600 running watts for 120V appliances and starts with a pull cord. It weighs about 100 pounds and does not include wheels, so think about where you will store and move it. It cannot power 240V appliances.

Questions about the LIFAN LF4800iE-Y001
How much running power does it provide?
3,800 watts on gasoline; 3,400 watts on propane. Starting watts are only available briefly, not for steady use.
Is it an inverter generator?
We have not confirmed the generator type in a matching manufacturer manual. 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 LIFAN LF4800iE-Y001?
This is the dual-fuel version of the LF4800iE, with different weight, dimensions, and propane output. We still need a matching manufacturer manual to confirm the listing. Check those details before choosing it for appliances you depend on.
