Have about 50 Hours on this thing and it runs/works great. I put a few heavy loads extending beyond output capacity and it grunted thru those fine. All my friends have Hondas of the same size. They do not have carb bowl drain, and other features. Plus this came in over $ 300.00 cheaper than a Honda.

This is the perfect sized generator for my hunting cabin in Maine. I use it to charge my batteries when there isn’t enough sun for my solar panels during the fall and winter. I was amazed at the great price and it arrived at my home rather quickly, seeing that it was shipped from California. Another awesome Yamaha product!

I have purchased three Yamaha generators from National Supply and the service has been excellent each time. I just purchased a Yamaha EF6300iSDE inverter generator and it was quickly shipped and received without damage, Yamaha packages the generators very well and National Supply makes sure their final shipping packaging is well done also.

The Yamaha EF6300iSDE is a well thought out design, Yamaha inverters are the best second to nobodies, they put out such clean power they can run medical equipment without issues. This EF6300iSDE started right up after installing the battery, oil and adding some fuel.

While there are plenty of China made clones sold at cheaper prices but they do not have the reliability of the Yamaha brand. I will spend the extra money and know I have the very best quality and longevity that you can have in a Yamaha. I will also purchase from National Supply because they have the best customer service and fast shipping.

Yamaha and National Supply are my choice when it comes to quality products and service.

Good communication from staff and was packed very well, no damage

Upgrading from a Champion 7k. It worked and broke, got it fixed but it runs 100% regardless of load and extremely loud.
The Yamaha by comparison is so much more premium, efficient and wow..so quiet!
Communication was great as it was in back order. Was packed very well, no damage and fired right up. Hoping I get many many years of trouble free power as I'm in Southern Florida.

Machine delivers it's rated output and then some. Noise levels under load are not bothersome at all. The large fuel tank (compared to others in this size range) is a wonderful feature, as are the fuel gauge and the carb drain knob. Shipping charges for this single machine were nominal; delivery took about a week, which was expected. I intend to order another one for parallel operation; should've done that initially and saved myself the shipping charges.

No words on how happy I am on my new twin Yamaha EF2200IS! Excellent customer service! You rock National Supply!

I ordered two generators from this company they decided to overnight them, at their expense and completely on their own to do this,🏆 I can’t believe they think that much of a stranger to get me the generators before hurricane Milton hit that’s amazing👏👏👍👍👍 sincerely your customer

Fast shipping and the part came in as described. The exact part we needed to finish the project.

My generator arrived with some minor damage (no fault of Yamaha, just from shipping). National Supply not only took care of it, they did so without flinching and at lightning speed. By far the most impressive customer service I've had in years.
The generator is awesome and typical yamaha quality. So its great!
I ended up buying another one for family.
The generator itself is built like a tank. The alternator is 2x the size of a northstar 7800w. Wheel kit has solid rubber wheels (not inflatable that will go flat) Oil pan is easy to check and service. The fuel-shutoff has a plug for easy draining of the fuel tank without disconnecting the line from the carb. At this point, I have literally nothing bad to say about the generator or the company selling it.
Don't risk your $$ with some big-box store crap with apathetic employees that don't know about the products their selling. National Supply is the way to go, hands down.

The fuel gauge and larger gas tank is a welcome addition over other brands. This thing is built like a tank and with regular maintenance will last for years.
Checks all the boxes for my needs as a back up for hurricanes in Florida.

Above expectations!

Our Yamaha 7200 is set up...legally...to power our entire home. With manual load shedding, turning off the how water heater, we operate our HVAC. I highly recommend a QUALITY synthetic 10w-30 oil! Operation here AGAIN in Florida has been FLAWLESS. Now on 2nd hurricane and 4 straight days running.

Covers the inverter completely, thanks.

I bought a similar-looking cable for less and returned it because it didn't fit. This one is OEM-grade. In the long run it's worth it to pay more, do the job once and right.
