Battery is 5 star rating.

Great communication, shipping was fast, and generator showed up in perfect condition. Haven't had to actually use it yet. Started on 2nd pull. Stop shopping, you found your best place to buy from. NATIONAL SUPPLY

Bought one about 4 years ago to power the camper. It's every bit as quite as a Honda. The only thing that could make it better in remote start. I bought an aftermarket kit and now it's perfect. Took me (first time doing this) about 2 hours to install using the supplied video. Installed the generator in the back of the pickup and rigged up so I could plug into it while traveling. Now I can start or stop the generator either in the pickup or the camper or anywhere within range. Works perfect and can't hear the generator at all from inside the camper. Yes, the truck needs to be withing range of the cord but that has never been a problem. Yet!

Battery worked just fine. Started up my generator first try. No issues.

Very happy with my recent purchase of the Yamaha generator. Works as it should. Ran my a/c unit when hooked the two generators together .

Still in the box . I didn't unpack it yet 'cause I'm moving down to Florida.
I just rely on Yamaha excellent reliability, and trust their reputation so I'm going to take a chance on warranty time.

My second one of these. Solid. Quiet. Reliable. Yamaha doesn't make junk. There is a reason these are more expensive then other generators in this class. Peace of mind that it will work every time. If you maintain it and stay in the usage guidelines you will get every penny's worth of your investment back. It may outlast you.

Generator works as it should. Have only used it for thirty minutes or less.

Would help if they came with some operator instructions.

Best price I could find!

These generators preformed flawlessly. Great power and option to use one or two, as needed. Exactly what I needed. Great purchase experience also. Thank you!

I needed a portable generator on short notice and was pleasantly surprised to have it delivered in 3 days and in time for my trip. It was delivered in perfect condition and has run flawlessly. Highly recommend

Just what I needed at a reasonable price. Thank you!

Selected this particular model since it is NOT electric start, pull start only. The ONLY reason it did not start on the first pull upon new assembly was due to choke lever not set correctly. Pulled it three times then as soon as choke was set to full, it started immediately and every time thereafter. Solid frame construction, quiet operation, everything you would expect from a "Yamaha" brand of equipment!! Only (minor complaints) 1) CO sensor VERY sensitive, shut it down quickly after startup in my garage. 2) Unable to register the unit through Yamha for warranty. Company is working to resolve this with Yamaha

This is the second time buying this tune up kit, for my generator. It's contains everything needed and works perfectly
