Should You Buy It?

This is a fairly powerful and affordable portable generator, and judging by the experience of the majority of its owners, you will get a good machine were you to choose to buy it.

It's able to operate with both gasoline and propane, so you can have a much more flexible and versatile option. But, like most of its competitors, it's not flawless.

Customer service in whatever sector is rarely going to please everyone. While being put on hold or thrown to the mercy of a call center is extremely frustrating, it's a fact of life nowadays from which unfortunately there seems to be no escape. 

In terms of the warranty, most if not all manufacturers have very similar terms, and buyers having to pay for freight costs seems to be the norm. We have more to say about warranties in general here.

However, for many customers this generator has proved to a good solution when for whatever reason the grid has been off. So if the power it delivers and the price coincides with your needs, then this looks to be a decent option for your shopping list.

The following has more detailed information on the generator.

Overview of the Generator

Duromax XP4850EH Components
The XP4850EH is a medium power dual fuel portable generator with an all-metal construction to ensure durability and reliability in tougher conditions.  It can power lights, a refrigerator and a home air conditioner. On a jobsite, it can power high amperage tools. With these capabilities, it's a good choice for ensuring some home backup when you need it, and aiding your jobsite work.

Controls and Features

Control Panel of the DuroMax XP4850EH
The control panel has a three-way rocker switch that electrically starts/runs/stops the generator (a manual pull recoil cord is also on the rear).

For your connections, it has 2x120v household GFCI outlets and 1x120v/240v 30A twist lock outlet. All have circuit breakers to protect the generator from overload conditions. In addition, there is a voltmeter and 12v DC posts for external battery charging. Owners are warned that:

● Only the 120v receptacles must be used to connect 120v devices.
● The 120/240v receptacle can be used to connect 120v devices, using an appropriate adapter.
● Only the 240v receptacle must be used to connect 240v devices.

An MX2 switch allows you to choose between operating the generator at both 120v and 240v simultaneously, or get the maximum power from each of the 120-Volt receptacles, making it Ideal for RV use.

The generator has a sensor that shuts down the engine when the oil level falls below a safe limit. It also prevents you from starting under the same conditions.
 
The unit is EPA Certified and CARB Compliant, so it can be used in all 50 states.

Do not operate this generator in an enclosed environment to avoid serious risks from carbon monoxide poisoning.

Power Output

The XP4850EH produces 4850 starting watts and 3850 running watts when using gasoline with its 208cc 7HP engine. On propane, the power delivery falls to 4608 starting watts and 3658 running watts. 

With these amounts of power you can run your lights and most of your household appliances, such as a refrigerator and a home air conditioner. It also has enough juice to allow you to work with high amperage power tools, say on a jobsite.

This model uses traditional generator technology and incorporates "Surge Arrest", which provides a degree of protection from power surges. But if you plan on connecting sensitive electronics, you will need a UPS/line conditioner to prevent fluctuations potentially causing damage.

Power outputs can be significantly affected by ambient temperatures and altitudes. Look here for more information on this because how much power your prospective generator can deliver may depend on where you live, 

Weight

This generator weighs 122lbs. It comes with never-flat rear wheels and a foldable handle designed to make it more portable. Not every buyer is a fan of the never-flat style of wheels and there are alternatives available.

Noise Level

While there are no established standards for measuring noise levels, the sound level specified for this model is 69dB, which is said to be about as loud as a dishwasher.

What Most Buyers Like

Most owners give this 5-stars, though it also gets fewer stars too. The majority say it's compact, super easy to assemble and get going with the electric starter. The dual fuel option is great as gas stations quickly run out during emergencies.

It's an excellent option as a partial house backup generator at a very affordable price. In terms of quality it's what you should expect from the economical end of the power generation sector. 

What Some Buyers Like Less

The comments here don't reflect the overwhelming number of positive views expressed by customers. But it's worth alerting you to some issues raised by people who are less than happy with the product.

The complaints include poor factory workmanship, cheap materials, unavailability of spares and poor instructions, as well as noise. Some buyers say customer service is mediocre with staff parroting scripted responses. Others said they got no response at all.

There is an apparently attractive 3-year warranty with DuroMax generators. But as one owner found, the devil is in the detail. On reading the warranty document it becomes clear that only parts are covered. Buyers are responsible for shipping costs and doing any work required themselves, even if they have no mechanical knowledge. 

Some owners advise that to prevent the wheels from flattening over time you need to move the generator frequently. One customer had one no-flat-wheel develop a flat spot after sitting for about 4 to 5 months. "It now it thump-thumps as it rolls across the garage floor". 

A few find that adding oil is difficult because of what they see as a poor design. And the 12v outlet actually measures about 20v DC. So if you're planning on connecting a 12v DC appliance, they warn you could end up in trouble.
