How much power does the ERAYAK 4500P Gasoline give you?
On gas, this model is rated for 3,500 running watts and 4,500 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.
| Fuel | Running watts | Starting watts |
|---|---|---|
| Gasoline | 3,500 W | 4,500 W |
Is this model a good fit for you?
This is the gas-only, pull-start 4500P, not the 4500PD or 4500PDE. Its manual gives 3,500 running watts, 4,500 starting watts, and 120V output. The RV adapter changes the connection, not the voltage or available power.
The manual lists four hours at rated power from an 8.5-liter tank. The website's eight-hour claim does not state the same power use. Noise figures also differ in how they are measured, so do not compare them as if they were the same test. Use the manual's 54-pound weight and dimensions for storage planning.
The details for this model
Model: 4500P Gasoline. Manufacturer part number: 4500P Gasoline. 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: Amazon model name says 4500PD but model number says 4500P Gasoline; only matching gasoline 4500P manufacturer information is used. Official headline says 55 lb.; matching manual says 54 lb. Official page says 60.5 dB; manual gives 74 dBA sound pressure / 94 dBA sound power without comparable conditions. Amazon dimensions 20 × 12.2 × 19.3 in. differ from matching manual 19.88 × 16.93 × 20.25 in.

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 4 hours at rated 3.5 kW output (matching manual). The listed gas tank holds 8.5 L / 2.25 US 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.
Keep approved gas containers, rotate stored fuel, and plan where you can refill them. A bigger wattage number will not help if you run out of fuel. 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 →

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; no electric or remote starting. Keep the starter battery charged as the manual recommends. Practice any backup starting method before an outage. It weighs 24.5 kg / 54 lb. (matching manual). Wheels can help on level ground, but they do not make stairs or lifting into a vehicle easy.

Questions about the ERAYAK 4500P Gasoline
How much running power does it provide?
3,500 watts on gasoline. 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 Below 1.2% claimed on manufacturer page; load condition not established. 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 ERAYAK 4500P Gasoline?
