Duromax MX4500 Portable Generator

Duromax MX4500 Portable Generator

and MX4500E Electric Start:

Power Output and Generation

The Duromax Elite MX4500 and MX4500E gas powered portable generators are equipped with a 7 HP Duromax air cooled 4 stroke OHV engine which let them produce 3500 watts of continuous power while being able to surge up to 4500 watts.

Additionally you have a 12V terminal at 8.3A (~100 watts)

With 3500 Watts of continuous power available the outlets of L14-30R and 5-20R make it easy to use a majority of that power in combination for relatively short durations.

Utilizing just the 20 amp outlet allows you to use up to 2400W both outlets are powered by the same circuit. The manual nor wiring diagram gave the circuit breaker rating, but could be assumed to be 20 amps.

When using the L14 receptacle you can get two 120V lines (Switched for RV use) at a max of 14.5 amps each (2 x 14.5A = 29A) or in 240V mode at 29 amps.

Fuel Type and Noise Levels:

The Duromax MX4500 and MX4500E portable generators use gasoline as their fuel. They have a fuel tank capacity of 4 gallons and is advertised to run for 8 hours at 50% load capacity. However, the owner’s manual we reviewed indicated a 12 and 14 hour run time at this same load. To be safe the 8 hour looks more typical of this size of generator.


Both these generators are normal noise makers while running, advertised as producing 69 Db of sound when operating. This is presumed at the typical 23 foot range. This is a typical noise level of larger generators. I can believe a few sellers are passing this off as quiet!

Dimensions and Weight

The DuroMax Elite MX4500 and MX4500E gas powered portable gas powered generators have overall shipping dimensions of 28 x 29 x 36 inches ( H x W x L ) and shipping weigh at 140 lbs.

The stripped down version of the frame has it at 17 x 17 x 23.2 which seems to more actually fit the space requirements, but one does have to consider the wheels and handles to a lot for enough space.

Full of gas these machine are going to be close to 160 lbs, but should be easy to move around with the wheel kits. There are owners that believe that the weight is not well balanced and forward of the wheels. This appears to be debatable based on your point of view.

Typical Uses and Needs

The Duromax MX4500 and MX 4500E gas powered generators are capable of producing 3500 watts of continuous output while being able to surge up to 4500 watts. These are portable generators which use gasoline as fuel and have a gas tank with a capacity of 4 gallons which lets them run for 8 hours at 50% load capacity.
