How much power does the DuroMax XP5500HX give you?
On gas, this model is rated for 4,500 running watts and 5,500 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.
On propane, you get 4,275 running watts. That is 225 fewer watts than on gas.
| Fuel | Running watts | Starting watts |
|---|---|---|
| Gasoline | 4,500 W | 5,500 W |
| Propane | 4,275 W | 5,225 W |
The details for this model
Model: XP5500HX. Manufacturer part number: XP5500HX. 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 current manufacturer table says remote start, but the model has existed in earlier configurations. Confirm the specific shipped revision and included remote before relying on that feature.

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 19 hrs hours at 25% gasoline power use; 9 hrs hours at 50% gasoline power use. The listed gas tank holds 4 Gallons. 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. For a well pump or central air conditioner, have an electrician check voltage, running power, and startup demand. A 240V outlet alone does not guarantee enough power.

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: rocker switch. Practice starting it before an outage so you know you can use it when needed. It weighs 128-lbs. Wheels can help on level ground, but they do not make stairs or lifting into a vehicle easy.
The listed warranty is 5 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 →
Other generators to compare
WEN GN5600 →
The GN5600 provides 4,500 running watts on gas and comes with wheels. It is a 120V-only generator, even though the description mentions a transfer switch. It cannot power 240V appliances.

EFURDEN EDOG-21 →
The EDOG21 provides 4,500 running watts and 6,000 starting watts at 120V. It cannot run a 240V well pump. Its 30A outlet has a separate limit, so you cannot draw all 4,500 watts through that one connection.

Briggs & Stratton Q6500 30761 →
The Q6500 30761 is an inverter generator with 5,000 running watts and 6,500 starting watts, according to the brand's store. It also lists CO Guard shutdown. Its enclosed design may appeal for home backup, but noise claims need matching test conditions to compare fairly.

Questions about the DuroMax XP5500HX
How much running power does it provide?
4,500 watts on gasoline; 4,275 watts on propane. Starting watts are only available briefly, not for steady use.
Is it an inverter generator?
No. It is a conventional generator. A voltage regulator does not make it an inverter. 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?
Its 120/240V output may work with a suitable 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 DuroMax XP5500HX?
If you do not need a huge generator, this smaller HX model gives you gas, propane, and 120/240V output. It provides 4,500 running watts on gas. Its wheels help on level ground, but lifting it is another matter.
