Pick one of these up at Costco for $599.99.

 

Some of the things I like about it are;

 

1)  Cheaper than the Honda or Yamaha versions

2)  Manufacturer 3 year warranty (Yamaha only offers a 2 year)

3)  Costco stands behind the products they sell and have a generous return/exchange policy.

4)  It is powered by a Yamaha MZ80 engine, the same one in the Yamaha EF2000i Genny

5)  This model (2000iQ) can be run in parallel with another 2000iQ. (Cables are extra)

6)  USB Charging Portal on the front.

7)  Gas Tank gauge.

8)  You can run out the gas before storing, so you don't gunk up the carb.

9)  Whisper quiet (on par or better than the Honda or Yamaha)

10) 45 lbs (even a woman can carry it around)

Every time I go into Costco I feel the urge to buy one of these.  Kind of hard to justify since I have a built in.  Can't explain it, just want one.....

I have owned two of these since May 2014 and have used them several times boondocking.  On a recent trip in early September, it was 19 degrees one morning at 7800 ft altitude, and the generator started with 3 pulls and ran just as it should.  I bought 2 because I wanted to be able to run the A/C boondocking if I want to, and could not mount a larger 4000W generator that I had when I bought my 2014 2385 on this TT's rear bumper (too wimpy a bumper).  The two cost me less than one Honda or Yamaha with the same specs.  With a little modification to raise the shelf a couple of inches, both generators fit in the front storage compartment on the right side of my TT and they are light enough for me to lift and stow without too much trouble.  I did notice less power at this altitude; one would run the microwave, but it was pretty close to max load, whereas at lower altitude, one runs the microwave just fine.  As an aside, I am careful to avoid ethanol gas for them and all of the rest of my small engine equipment, as it tends to collect water more than non-ethanol gasoline.  So far, so good.

  and concur, these little 80cc motors do tend to struggle at an altitude greater than 6,000 feet. When I first tried mine, it had about 1/2 hour's use on it and probably hadn't properly broken in yet. At 6500' running the micro, it bogged down quite a bit and sometimes would recover, sometimes not. I just take both along now and they work much better in tandem. For approximately $1330.00 which includes tax, to have 3100 watts of relatively quiet genny power is an unbeatable price.

Oops, I almost forgot a few other modifications/info that you'll need!

 

1)  Generator Hour Meter Link  (easy mod to make, just wrap the wire around the spark plug wire and secure it well) 

2)  A nice cover  (Yamaha 2000 covers fit perfectly!)

3)  Link for the dipstick and magnetic plug

4)  A few extra Spark Plugs (these are the correct ones)

I also broke my generator in, for 20 hours (not all at once) and then I changed the oil (Yamalube)

 

Don't let the burning credit card scorch yer buttocks!

Yes Randy, the cover is excellent.  I tried an off brand cover but it was a mess, no handle to carry the darn thing like the Yamaha cover has!  It fits like a glove and I wouldn't be without one.

 

I think I bought mine through eBay, let me look for the price, as I think I only paid $32,00/ea.

 

$36.99 Free Shipping from eBay:

I just did a bit of shopping around and found these covers for a better price than Amazon. $38.50 each and even though there's a modest $6.95 shipping charge, they don't charge tax here in Nevada like Amazon does. I went ahead and ordered two.

James........are ya paying attention? 

Darn, wish I'd seen that first before ordering. I always forget to check e-bay. I have this age old stigma firmly planted in my cranium that it's an internet garage sale of sorts and forget that there are a lot of legitimate vendors doing business there. Oh well, mistake only cost 10 bucks.

Interesting observations.

 

When I first got to Doheny, the genny ran the A/C and the Microwave (obviously not at the same time)

 

Now that I'm powering my laptop, DirecTV box, and the 12v Winegard G2 carryout, I'm not able to run the A/C or microwave.  Seems like the extra junk (the laptop, etc) pushed the genny over it's capacity or capabilities.

 

Don't get me wrong, it's still able to power up and charge the 2 AGM batteries I have etc, but I'm kinda disappointed to tell you the truth.

 

WoodGlue

Don't be disappointed.  Just get another and a parallel cable. Running the AC is pushing the extreme limitations of these gens. Even though you may get the AC to fire up, if you saw the accompanying voltage drop, you'd be realizing that even though it runs, who knows what kind of electrical component damage could result. I know another gen and cable will set you back approximately $700.00, you'll be sittin there with 3100 watts of power and should be able to run pretty much everything.

How do you like them genny run times there at the park? :-(

When using the generator for the air conditioner:

FIRST, Turn your fridge from Automatic to LP.   You're camping off circuit, but IF you don't do this, when the generator starts, it will think it's plugged into the wall socket and switch back to AC (from the generator) That's 3 amps of relief the generator doesn't have to provide.

 

SECOND throw the blue breakers shown below.

   MAIN  -                            30 amps  (This has to stay on)

1 GENERAL PURPOSE         15 amps   (these are your receptacles. Leave them on so your laptop will have power from the generator, unless you are running it from 12 volts. It doesn't take that much.  At last resort, turn these off.)

2 AIR CONDITIONER             20 amps  (Leave on.)

3 MICROWAVE                 15 amps  

4 CONVERTER                     15 amps  (this is taking your 'onboard battery charger' out of the circuit.  For the time you have this switched, you are running just on batteries and the converter charger isn't replacing amps in your batteries.  Once the AC has been shut off, if you reactivate this breaker, the generator will then start charging your batteries. 

5 WATER HEATER (electric)   15 amps (this is probably not on, but it's a sure killer if it is.  Sucks lots of generator amps.)

 

 

Woodglue, Doug's suggestions are good ones.  I bought a second 2000iQ because (1) it gives me redundancy, (2) 2 are needed to run my A/C especially when I boondock at higher altitude, (3) 2 are needed to run my microwave above 6000-7000 ft, and (4) if nothing else, it's a $600 1 gal gas can!

Good point, Brian.   Woodglue would only need one for most 120 volt times, but if it comes to needing the air conditioner, plug in both.

WoodGlue, it's worked out well for me, even though I hated to shell out another $600.  However, I didn't have much choice because it's too difficult to handle/carry a 3000-4000W single generator, which is more than I need most of the time (except for A/C and high-altitude microwave running).

 

Brian

OK, thanks to all of my "Friends" here on LOA helping me spend my money, I just came home from Costco with one of these!!   And I have a surprising report to make.  It runs my 13.5 BTU A/C in my driveway, about 2600' elevation!!!  Didn't even struggle.  I'm sure the result will be different at higher altitudes, but for now I'm happily surprised....

Randy, I'm guessing the EF2000is cover is the right one???

 

Never mind, figured it out.......

BigE, that's great that only one 2000iQ will run your A/C at 2600'!  However, as you point out, altitude will impact it.  While the specifics depend on engine type (2 cycle vs 4 cycle) and carburated vs fuel injected, a rough figure is about 3% power loss per 1000 ft elevation from sea level.  It isn't exactly linear at lower altitudes, but when you get up to 6000-7000 ft, it is very noticeable.  For example, my 2000iQ runs my 900W microwave (that's output in the microwave; the input power is actually 1200W) just great at home at 2300'.  At 7000', where the generator output loss would be around 21% or a steady-state output of about 1400W, it will run the microwave but not at its full rating, as indicated by the longer cooking time.  I didn't have time to hook up and parallel my second 2000iQ the last trip, but will test it next time.

The problem with using ethanol enriched fuel in small engines is the fuel does not cycle through like it does in a motor vehicle. That fuel can sit in any small engine for months, and some are designed with alcohol proof hoses and tubing and some are not. The biggest problem with the ethanol enriched fuel is phase separation, where the alcohol breaks down and attracts water vapor and moisture, and you end up with a slug of water on the bottom of the tank, carburetor, fuel lines, etc., and pure gas sitting on top of that. On any small engine you're better off using non-ethanol fuel at 87 octane -- or -- using an enzyme-type fuel conditioner that prevents the phase separation. The non-ethanol fuel costs more, but by the time you add the enzyme you're at about the same cost. There are a lot of fuel stabilizers on the market, and most do not prevent phase separation. The two most popular that do are Stabil Marine Formula (blue/green color, not the red), or Starbrite. You can find them at Walmart, most every marine or boating store, and a lot of the auto parts stores. Other than these two you need to read the label carefully to verify that it does stabilize and prevent separation. I use both of these treatments in every small gas engine around the house--lawn mowers, snow blowers, weed trimmers, my Gator UTV, small Smart Tools generator, my big Generac house generator, chainsaw, Mercury and Yamaha outboard motor--everything other than the cars. Mid or premium grade fuel will not help, though a few distributors supply ethanol free only in 90 or 93 octane. The higher octane actually has less energy but does prevent detonation (knocking). 

No, not bad info. My manual says the same thing, so the fuel lines are designed to use ethanol fuel. These generators don't use a lot of fuel, so there is a good chance that without an additive you can have the separation--or use 100% gas. Cars go thru a tank in a week, that fuel may be in a generator for months. The only benefit for using a higher octane fuel than an engine is designed for is you're donating extra profit to the refiner/distributor/dealer. Every manual for every motor has the designated fuel octane requirements listed and there is absolutely nothing to be gained from exceeding that.
