Besides, the Honda Generator EM6500S is quite compact for a generator with the size of engine it runs on. To be precise, the Honda Generator EM6500S measures 41.4 x 27.8 x 28.3 inches.

Honda Generator EM6500S Review; Power Output

The Honda Generator EM6500S is powered by a Honda iGX390 engine. This engine has a displacement of 389cc.

In case you are wondering what displacement means, it is an essential factor that can help to determine an engine’s power output and fuel efficiency. Basically, the higher the displacement of an engine, the more power it will be able to offer.

On another note, the lower the displacement of an engine, the less fuel it can consume. The reason for this is that displacement directly affects how much fuel an engine needs to draw in to create power and maintain its operation.

In most cases, an engine with high displacement will draw in more air/fuel mixture for its operation. Due to this, it consumes more fuel.

However, due to some other factors like fuel delivery, ignition systems, valvetrain layout, etc; this theory may not hold in some cases.

In the case of the Honda Generator EM6500S, its high engine displacement certainly enables it to generate high power output.

To be precise, the Honda Generator EM6500S is capable of delivering 6,500 watts of consistent power. This generator delivers 10 seconds of 7,000-watt power for starting larger equipment.

With this amount of power, you can depend on the Honda Generator EM6500S to run basically every electrical appliance in your home. During my research, I also visited Amazon and other credible websites to discover what people were saying about this generator’s capabilities.

Based on the comments and reviews I came across, this generator can power your refrigerators, furnace fans, TV sets, and other home appliances.

Compared to the Champion 76533 and the Honda EU3000iS, the Honda Generator EM6500S is much more powerful. The Champion 76533 offers 3800 Watts of running power.

Meanwhile, the Honda EU3000iS generator produces 2800 Watts of running power.

Honda Generator EM6500S Review; Efficiency

One of the impressive features the Honda Generator EM6500S offers is its 120/240V Selector switch. To give more detail, this generator allows you to choose between using both 120 and 240 Volts, or 120 Volts only.

With this feature, the Honda Generator EM6500S offers more usable power and more performance flexibility.

Let me quickly explain. This selector switch allows the total power output the generator produces to be available through any of the 120-volt outlets.

The only thing that can limit this operation is the maximum capacity the individual outlet can take. Regardless, the feature enables you to power appliances with large wattage requirements.

In addition, the Honda Generator EM6500S also comes with a Honda My Generator app plus Bluetooth capability. The My Generator smartphone app allows you to operate and monitor the generator with an incredible amount of convenience.

This app comes preinstalled with features like wireless start/stop, operation monitoring, and service reminders. These features all work while utilizing Bluetooth connectivity on the generator.

On another note, the Honda Generator EM6500S also offers consistent power with its iAVR (Intelligent Automatic Voltage Regulation) technology.

This technology makes sure that they produce a consistent flow of power regardless of the load it is powering. Thanks to this feature, you get a reliable power source and stable power for your sensitive equipment.

Honda Generator EM6500S Review; Fuel Type and Runtime

Remember when we talked about engine displacement in the previous section? In the previous section I mentioned that an engine with high displacement will draw in more air/fuel mixture for its operation and as a result, it will consume more fuel.

You may have been wondering if that’s the case with the Honda Generator EM6500S since it has a high engine displacement. Surprisingly, the Honda Generator EM6500S offers a fairly reasonable runtime.

With its 6.2-gallon fuel tank capacity, you can expect to get 6.4 hours of continuous usage from the Honda Generator EM6500S at a full-rated load. This means that even when you power numerous home appliances at once, the generator can last you over 6 hours 30 minutes.

However, if you don’t subject this generator to power too many appliances at once, it will last a bit longer. At 50% out of its full capacity rated load, the Honda Generator EM6500S will run for 9.8 hours.

Fortunately, this generator runs on gasoline. Since gasoline is a common fuel type, you won’t have to worry about the ease of purchasing it.

Honda Generator EM6500S Review; Outlets

You will get all the basic outlets you need on this generator. To start with, there’s a 30A 125V locking plug present among the outlets the Honda Generator EM6500S offers.

The Honda Generator EM6500S also offers another locking plug. However, this one is different from the one I previously mentioned.

This one is a 30A 125/250V locking plug. These outlets are quite similar to the ones you have around your home.

You can use them for various electronics.

In addition, these two outlets come with ground-fault circuit interrupter (GFCI) features. In case you are not aware of what this means, let me explain.

A GFCI measures the electrical current going in and out of your appliances. Whenever the returning current from any of your appliances diminishes, it shuts off, signifying that the current has followed an alternate path.

To understand the operation of the GFCI, consider this scenario. Whenever you drop a power tool into a muddy puddle, the GFCI will always go off before you will feel the current electrocuting you.

Moving on, the Honda Generator EM6500S also comes with electronic circuit breakers. You can flip the main circuit breaker and sub-breakers if you have to reset the output of the generator’s outlets.

The main circuit breaker is capable of controlling the total output of all outlets on the generator. Meanwhile, the sub-breakers limit the current the generator delivers through its duplex outlets.

Thanks to these breakers, you don’t have to constantly about harmful surges occurring.

Honda Generator EM6500S Review; Noise Rating

Considering the amount of power it generates, the Honda Generator EM6500S is not too noisy.

When it is running under the maximum amount of load, it produces a noise level of 66 dB. With 50% of a full capacity workload, the noise the Honda Generator EM6500S produces reduces a little.

At 50% load, the Honda Generator EM6500S will produce a noise level of 64 dB. In general, these noise ratings are better than the 66 dB+ other generators in its power range emit.

Take, for instance, the WEN 56352 which emits a 67 dB noise level. The Honda Generator EM6500S is also slightly quieter than the Champion 46596 which emits a noise level of 68 dB.

Overall, the Honda Generator EM6500S’ low noise rating means that you can run the generator throughout the night without disturbing your neighbors.
