Here's my experience: Ordered Thursday afternoon. Delivered Tuesday evening. Set up (30-45 minutes), start up (recoil) and run. Charged house batteries for two hours, turned off and went to bed. Woke up next morning, electric start, run, charge batteries (and run whole house) until ready for work.... shut down, come in and write review at work (on my break - no internet at home). It starts really easily (on LPG - I haven't tried gasoline yet, but have that in case one of my smaller LPG tanks runs out), runs quietly enough that the rain on my roof was louder than the generator. I may need to adjust the engine governor, as I get an overspeed indication on my inverter. Otherwise it performs like a champ!
C'mon, people... look at the big picture: you're paying rock-bottom price for a unit assembled in China by workers who typically make less in a week than many of us make in an hour. Let's fairly assess the value of the unit:
1) The engine is a Honda 'clone', making 7 hp. It was probably reverse engineered in much the same manner as Ural motorcycles were reverse engineered from 1940s era BMWs. There's no R&D. There's no search for tiny modifications which will result in minor improvements. There's no re-tooling for newer versions and none of the intellectual overhead Honda has, but the engine is based upon a design which we know to work. Even with good maintenance, this engine will not likely last as long as the Honda upon which it was based, but at 1/3 the cost (or less) it can be replaced when needed (and Amazon sells the replacement engine!)
2) This is a dual fuel generator set, from the factory... no messy modifications. It is warranted for 2 years. If you modify (or purchase) a Honda generator retrofitted for use with LPG, you'll find that Honda will not honor the warranty on their product.
3) Noise level? I read reviews where people were complaining about how loud this unit is! I fired mine up and my wife didn't even know it was going! Go and listen to other generators before you complain that this one is loud! Compared to a Honda EU3000iS (MSRP: $1900+), this unit is louder, but is still not loud.
Really.... if you want an analogy, buying this generator is like purchasing a base model Ford or Chevy and then complaining that it doesn't have fit and finish or run like a Mercedes or a Porsche. You have to look at it realistically. My Dad always said "You can't drink champagne on a beer pocketbook".
While this may be a one star Mercedes, it's a five star Ford!
Right now, this little guy IS my primary source of power, and it's looking very good. I'll update as things progress.
UPDATE: I've now had this little jewel charging my batteries for over a month. It has NEVER failed to start. I've had three really minor issues... and two can be chalked up to operator error.
1) I have begun running the generator on gasoline, instead of LPG, because gas is actually cheaper than propane, right now. This little guy can run my refrigerator, freezer, well pump, washing machine and some lights (as well as other small appliances - TV, DVD player, etc) AND charge my batteries.... some of these things run simultaneously. It runs a looooonng time on a tank of fuel. The little fuel gauge on the tank, however, doesn't always work right.
2) Speaking of running all these things - I had it wired to run 120 volts off one leg of the 30 amp/240 volt outlet. The breaker kept popping. I then changed it to run off the 20 amp 120 volt outlet, and all is well with the world. Operator error.
3) I have (he said, embarrassed) had the opportunity to "test" the low oil shut-down. Needless to say, it works. Operator error.... again.
SECOND UPDATE: The generator has been running every day since its arrival. Never a problem starting on either gasoline or LPG. One issue I've begun to notice, though: Since gasoline is currently still cheaper than LPG, that has been my fuel of choice; the issue I've noticed may - and may not - be related to running on gas. After the number of hours this has run (I estimate around 200 - no hour meter [note to DuroMax: a cheap hour meter might be a good idea for the next incarnation of this set]), the engine has now "broken in" and tends to run a little fast. As a result, the output shows "overspeed" on my inverter. I confirmed this by choking it down, a bit, and the error signal went away. I'll need to look at adjusting the run speed on the engine. Otherwise, it keeps chugging along! The Little Generator that Could!
I contacted support via email about being able to use synthetic oil after it is broken in using conventional oil. They responded quickly and gave me the ok. Do not use synthetic oil to break a motor in ONLY conventional oil. I also contacted a friend of mine who is a motor genius and asked for recommendation on what oil to use. He recommended Honda 10w30 as his oil of choice. I followed his recommendation. He also was the person who advised the 45 minute to 1 hours break in under light variable load.
It took (4) attempts using the starter button to start motor for the first time using propane as fuel. This due to my caution and generally letting the gas work its way to motor. ONE VERY IMPORTANT note for people to understand is not riding the "STARTER BUTTON" for more than 5 seconds AND waiting 10 seconds between start attempts. If you ride the starter button too long you can burn the starter unit up and it will be worthless. I only pushed the button 3 seconds being cautious as first time start up.
On the fifth start it fired right up instantly and ran well the entire time. I am sure it would of started right up had fuel ( propane) been in the system. I gave sound a 5 star rating some might argue that, but generator motors will make noise. I have a spot that absorbs most of the noise so for me it is fine.
Motor sounded solid, ran well, and completed break in task. The electric start, wheels/handles, and weight are all good for the size. I purchased back up brushes and voltage regulators for it as a precaution looking into future. Generally if something is going to go wrong with items like this it will happen soon and having an extra voltage regulator ( wearable part) is prudent.
I really like the propane fuel as most my needs for a generator will be short term. I do not like to leave gas in the tank at any time. I always shut fuel valve off small motors and let gas run out then drain tank. I also use Non-Ethanol fuel only. Being aware of 5 sec start, 10 second rest, with electric start and use of non-ethanol gas only (draining after use and emptying carburetor) are a few things that will make the life of the product hassle free and reliable.
