Review of the Champion 100302 RV-Ready DH Series Open Frame Inverter Generator

There is no electric start, which many people would like to have seen as a feature on this model.  And, as you will see, there is the question of more noise than expected. But this tends to be an issue with most generators because noise remains very subjective, and you might very well have a different opinion. So if you are happy with the specified 64dB, then this inverter could be a very good buy. It's reasonably powerful and comes with the benefits of inverter technology.

Evidence from the reviews we have seen clearly shows that all manufacturers have a minor number of problems with defective units. For many people, it might seem like the luck of the draw. But when customers have had problems, Champion more often than not reached out in an effort to resolve them.

As usual, you should confirm you don't need more or less power output for your needs, both now and in the near future. And if you do opt for this one, remember it's pretty heavy. So protect your back by getting the optional wheels too.

The Model 100302 is a Digital Hybrid Open Frame inverter said to be 50% quieter and 20% lighter than a traditional 3500 watt generator. It's aimed at RV owners, campers, those working on smaller jobsites, and others who want a source of limited home backup power. 

The controls are well-laid out in a Quick Touch Panel. The receptacles include a 120v 30A RV (TT-30R), two 120v 20A household outlets (5-20R) and a 12v DC automotive-style socket. There is no automatic voltage regulation on the 12v outlet.  The unit also comes with a dual USB adapter and battery-charging cables. The 120v 30A outlet is for direct connection to your RV with an appropriate cable extension. 

There is no electric start on this model, just a manual recoil cord.

An Economy Mode uses Champion's Quiet Technology and Extended Runtime. This monitors power draw and adjusts engine speed according to the load, thereby reducing noise and improving fuel economy. It also promotes a longer engine life.

The 100302 doesn't have an hour meter or fuel gauge. However, there are warning lights for low oil level and overload, plus a light to indicate the unit's readiness. The engine will cut out if the oil level is too low and refuse to start until you have added more.

The generator runs continuously for about 17 hours at 25% load on its 2.9-gallon tank.

On this model, you have to drain any residual fuel in the carburetor after stopping the engine and before storing the unit. Taking such action prevents the problem of stale fuel gumming up the carburetor, which will stop the generator from starting however hard you pull the cord. 

Champion offer a 3-year limited warranty and free lifetime technical support.

You can see the manual for this generator here.

WARNING: The generator does NOT have a carbon monoxide (CO) sensor.

This model is powered by a 224cc engine made by Champion. It delivers 4000 starting watts and 3500 running watts.

With inverter technology you can connect sensitive electronic devices without fear of damage caused by spikes in the power output.

It is parallel capable, so you can double the power by buying the optional 100319 Parallel Kit for connection to a compatible unit.

Weighing in at 81.6lbs, this is one of the heavier inverters. Although you could move it on your own, two people are preferable in order to avoid injury. There is an optional wheel kit which you can purchase and fit yourself.

Champion have equipped this model with Quiet Technology, and say it has a decibel rating of 64dB. While this is about the equivalent of laughter, as an open frame model it is bound to be louder than closed frame inverters.

As an open frame inverter this generator received many 4 and 5-star reviews. It is a popular choice for buyers who want a reliable product with some extra power at an affordable price. 

Most users find the decibel level acceptable (but see below). It will run a 13500BTU A/C in an RV, but one owner notes it doesn't stretch to 15000BTU.

Starting the generator is easy using the manual recoil pull cord.

Buyers say they like its light weight, compactness, ease of use and affordability. They also give a thumbs up to the company for including a supply of oil and a funnel, so all you need is gasoline to get it started quickly for the first time. 

The 3-year warranty and Free Life-Time Technical Support is an added plus. 

Customer support, with a few exceptions, is regarded as good.

There are cases of units that are either dead on arrival or fail after some initial use. These customers say that the support they received from Champion could have been a lot better.

A lot of buyers think the generator is much noisier than advertised. One suggests a cheap muffler is to blame and, without a modification, the unit is RV-park unfriendly. Another owner says he discovered in the fine print that the decibel level was fit for a construction site. But this assertion may be a distorted interpretation of what the manual actually says near the foot of page 15.

A lot of people believe the optional wheel kit is essential for moving the generator around and should come as standard as it's not light enough to carry around.

A few units have been hard to start, and there has been an occasional fuel leak.

There is no separate gas line shut off to use up residual fuel in the carburetor prior to storage. Neither is there a fuel gauge nor an hour meter. Some customers think that these features should have been included in the design of this model.
