Yamaha EF12000DE - 9,500 Watt Electric Start Portable Generator

This generator is huge/heavy but very well made. It is noisy when in operation, nosier than I expected. The included wheel kit is very difficult to install going by included instructions. It came with a defective, from the factory, NGK spark plug, that I replaced for $5. As stated in the description no battery is included, the manual says 12v/30ah or 40ah battery. The included battery cable hookups (automotive style but smaller round) do not fit any battery I could find. Yamaha USA was no help with this when I called.

I had to rig my own nut bolt style for the recommended battery. Overall even with the problems I encountered I would purchase this unit again. R&L carriers that delivered put it in my garage with no help from me during a nasty snow storm, which was greatly appreciated & they are not required to do so its up to you to get it from the curb/road to your house. Mine did come with an hour meter installed even though the description says it has none. Just a FYI this generator is a near copy of the Subaru RGV12100.

Runs my whole house. Easy to start. No problems with this unit so far.

Best Generator I Have Ever Owned and I Have Had Hondas But Yamaha Tops Them as Far as Workmanship and Dependably You Buy a Better Generator

EXCELLENT GENERATOR DOES EVERYTHING YOU NEED IT TO DO TROUBLE FREE cANT WAIT TO USE AGAIN qUIET

After one year of considerable use I could not be happier with this generator!

Quiet, well-made, and easy to operate. Packaging and delivery were very good. Wheels are difficult to install; but once installed, the generator moves without much effort.

Have not had a chance to give it the full test, but it will handle our guest cottage. We were without power for almost 6 days with no running water. Thank God we live on a lake and could take lake baths.

The only disappointment was the advertised free shipping. Generators Direct had a $50 shipping charge added to my credit card. No big deal, but not as advertised.

I have used the generator once for an event lasting 8 hours. It worked flawlessly supplying 60Amps of power. Only comment I have is that I had to leave the event after 6 hours, run to a gas station and bring back more gasoline. On full load, it only runs for about 6 hours on a full tank.
