How much power does the maXpeedingrods MXR4000GT give you?
On gas, this model is rated for 3,200 running watts and 4,000 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 3,000 running watts. That is 200 fewer watts than on gas.
| Fuel | Running watts | Starting watts |
|---|---|---|
| Gasoline | 3,200 W | 4,000 W |
| Propane | 3,000 W | 3,600 W |
The details for this model
Model: MXR4000GT. Manufacturer part number: MXR4000GT. 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 listing gives a 2-year warranty while an official 4000W product page gives 1 year. Obtain written confirmation for the GT variant and seller.

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.
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 we like and what to consider
Reasons to consider it
- Runs on gas or propane.
- 3,200 running watts on gas.
- 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 3,000 watts.
- Noise figures depend on the distance and how hard the generator is working.

Questions about the maXpeedingrods MXR4000GT
How much running power does it provide?
3,200 watts on gasoline; 3,000 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. 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 maXpeedingrods MXR4000GT?
This is the dual-fuel MXR4000GT with Bluetooth, not the similarly named gas-only model. App controls can be handy, but it is still a 120V generator and makes less power on propane. Ask the seller to confirm the warranty because the published terms differ.
