Champion Power Equipment 100263, Best Built-In RV GeneratorWho needs the Champion Power Equipment 100263??

The Champion Power Equipment 100263 is an amazing built-in RV generator for those people who are looking for a generator to last them for a very long time. What’s even better is that this generator is quite affordable especially when compared to some other more traditional inverter generators. The 100263 generator is very popular because it can run on both gasoline and propane fuels which is very useful. The reason for that is because it’s ideal in cases when you can’t find one of the fuels for one reason or another.

Power and capacity

This generator has 3,100 running watts and 3,400 starting watts and can last for seven-point-five hours at just ¼ of load of gasoline fuels. However, when the propane fuels are being used, the generator will run for 14.5 hours at just ¼ of load. You will be able to find that the 100263 comes with a tank fuel of twenty pounds. This type of a tank fuel lets you have low refills and the performance will last for a much longer time.


There are also different kinds of outlets which is extremely useful as well for a variety of reasons. You will be able to find that there a DC outlet of 12 volt and two of 20-amp outlets of 120 volt and one 30-amp outlet of 120 volt. These outlets specifically will allow you to charge any of your electronic devices. Not to mention this generator will power up any more sensitive gadgets with ease. These gadgets are, for example, smart phones because they have THD that is lower than three percent.

Other specifications

When it comes to other specifications, the Champion Power Equipment 100263 comes with the Milwaukee OHV V-twin engine. There are two cylinders and one can see that there is a shift power as well which has estimated 717 of cc. Both of these cylinders are made out of cast iron and aluminum sleeves. This makes one great build because it makes the generator extremely durable and long-lasting. So, you won’t need to worry about the generator easily getting damaged in any kind of way.

Economy mode

Another great thing about the 100263 is that there is an economy mode. This economy mode can be switched on and used in cases if you want to decrease the usage of fuel. This will also decrease the sound so it means the generator will be a little quieter than usual. Not only that but the generator will also have a decreased electric output and will also allow the engine speed to be idle when while it is inactive, or without being loaded.

However, once you connect any sort of device to the generator, the engine will automatically start running in a regular way without decreased electric output. Once the economy mode is switched off, expectedly, the engine will be running at the standard speed.


When it comes to its weight, the Champion Generator 100253 weighs around 193 kilograms which is about 425 pounds (95 lbs). So you can easily notice that the RV generator is quite heavy and you can’t easily move it by yourself so you will need help. But, fortunately, this generator also comes with handles which are built in as well as mobility set which is also built in. Sadly, this really doesn’t make up for its heaviness entirely and its size, this will still be of a little help if you want to transport the generator.

Noise levels

Another great thing about the 100263 generator is that it really is quieter than most other generators or average ones. The noise rate is at 75 decibels which means it’s quieter than a dishwasher or a rather loud TV. This generator also has the parallel capacity which can greatly improve the power outcome of it. So you will be able to connect two of the same generators but, on the other hand, you’re going to ned a parallel capacity kit. This kit doesn’t come with the generator when purchased so you will need to buy separately.

On the warranty of the generator

The generator has a warranty of two to three year warranty and gives you free lifetime technical support which is really great. Also, it’s both approved by the EPA and CARB-compliant. You can use it in both forested areas as well as all states in the US. There is also a Cold Start Technology which lets the generator to start quickly in cold weather. One also gets a Quick Touch Panel that has access to almost all controls with ease so it’s super user-friendly.

Yamaha EF2000iSv2 2000W Built-in GeneratorDesign and appearance of the EF2000iSv2 2000W generator

In case you may not know, the EF2000iSv2 generator is just a better version of the previous EF2000is model by Yamaha. They may look the same when you see them for the first time but there are huge differences in how they work. For example, the EF2000iSv2 has a much better power output, meaning it’s more powerful than the model before it.

However, let’s start talking about Yamaha EF2000iSV2 alone. One may notice that the generator doesn’t have a very common design and appearance. That’s because it has round edges and the design is much slimmer than most other generators. It can even be compared to those radios people used to listen to in the old days. The only difference is that the generators gives us electrical current and not sound waves like a radio does.

Why do people like this generator?

A lot of experts and buyers have very positive opinions and reviews about this generators. One of the best things of the EF2000iSV2 is how quiet it is actually. It’s actually very light as well and the control panel it comes with is very user-friendly. On the other hand, the power output is pretty common and nothing unusual for a generator in 2000 watt category. The older version of this generators had 900 watts of running power but this one has a much better output – one of 1600 watts.


The EF2000iSV2 generator is also a very portable model so one can use it on their own camping trips. It can be also used for tailgating and all sorts of different off-grid activities outdoors. Its compact size and lightness is what makes this generator so great. Not to mention how quiet it is. Also, like said earlier, this model is a lot slimmer when compared to some other generators. So it makes it very easy to carry as it has a handle as well.

When it comes to its weight, it only weighs 44 pounds making the generator to be one of the lightest generators in this category. Another reason why this aspect is great is because it also means it is parallel capable. In simpler terms, you can take two of these generators without defeating the purpose of buying some random lightweight portable generator.

Noise levels

This generator is also ideal for recreational purposes because of how quiet it is. So you won’t need to worry about disturbing other people around you. The noise level of the EF2000iSV2 is measured to be of 61 decibels of rated noise level and 51.5 decibels at only 25% load.

Run time

When the load is only at 25 percent, the run time is ten-point-five hours which is probably the best run time from the off-grid power source. It’s very impressive because one wouldn’t expect the run time to be so long when you look at its compact size. One can also leaving it running during the night.

Power output

Like already mentioned previously, the power output is of two thousand watts of surge power. The running power is at 1600 watts which is pretty great in case you want to charge your own electronic devices or several appliances at home. The generator has a fuel tank which can hold up to 1.1 gallons of oil which is rather surprising.

It’s rather unusual for a generator of this power and run time to have a big tank. Due to that, one can also expect that the fuel efficiency is great on this generator. Inverter generators are famous for the clean electricity so you should expect that from this generator as well.

However, Yamaha company really takes the whole thing to a different level. There is a pure sine wave technology with Pulse Width Modulation which is transformed into a voltage stability of one percent and frequency stability of zero-point-one hertz.

Auto-decompression and auto-warm-up system

The reason why the EF2000iSV2 is so user-friendly is because it has a built-in auto-decompression system as well as auto-warm up system. The auto-decompression system is there to help in making the pull a lot more easier. And, the auto-warm up system increases the speed of the engine so it’s much easier to connect devices of high power.

Control panel and power outlets

The generator also has a control panel where you can find three power outlets. There are two AC power outlet of 120 volts and one DC outlet of 12 volts. On the downside, there are no USB ports on this generator. This generator is also compatible with EPA and CARB so you can use it in California as well.
