It's 3 hours st 25%
With the throw away, 60 hours at 25% with the 20# cylinder
Not enough power for my needs

The only question I have is how much does it eat (propane) it says run time at 25% load (175 watts) 3 hours.. That is not enough for a full charge on batteris that are at 50%. and also you can not use well you MIGHT be able to run a 60 amp converter (I'd limit to 45) Which will increase your time needed to recharge.

I do notice it shows both a "Throw away" and a 25 pound bottle. so is it 3 hours per throw away or per 25 pounder???? bid difference.

Still for 250.. Worth a look,


Please read about VA and watts etc. 60 or 45? Get real! Or maybe just read my previous post and have a look at the PowerMax spec sheet. It is not rocket science. [emoticon]

Looks like the little gas inverter is on sale again:

Sportsman Inverter


I really like mine, but I don't overload or abuse it either.

I wouldn't be too fast to claim that a little genny like that little Ryobi can't be very useful for drycamping in an RV.

We have a motorhome RV with a built-in 4000 watt Onan generator, but still carry along a little 650 watt Honda suitcase generator. One at a time - the little Honda will power such things as our RV's 45 amp converter, a hair dryer on it's low setting, an electric heater on it's low setting, and our little RV vacuum cleaner. It starts right up after sitting for months with gasoline in it, and will run 5-6 hours on 1/2 gallon of gas. It does all this at a full power noise level of 54 dB(A).

IMHO, small low-noise gas-sipping generators can be very useful for camping in tents or RVs ... even as a relatively quiet backup to solar when there's little or no sun.

I do exactly the same thing with a 800 VA generator.

May be folks like to zero-in on the weaker points for whatever reason.

LPG is a cleaner fuel. Clean enough to eliminate foul gas, storage. Oil stays clean, so do cylinder internals, valves and no muffler clogging.

Compromising means just that -- a trade off. Understand the specs, weigh the positives against the negative points. If there are too many negatives, move on...

Yes for me would be just for a battery charger in bad conditions.
Will eventually test a 20 amp portable, 35a WFCO, 40a PF corrected Xantrex.

I do know the difference between VA and WATT.
I also studied some rocket scientist
They were both on the same test.. I Passed.

The converter amps to generator watts are based on the recommendation of others for PRogressive Dynamics 9200 serie converters. they tell me that a Honda 1000 can only handle a 60 amp.. I know a Gernerac 1000 (True 1000 watts) can power a 9180 with charge wizard but I'm told a HONDA can not if the batteries are low. So since thi is a 900 peak (not 1000) I downgraded one converter from those. It might run a 60 but it would be running at maximum capacity.

But I do know the difference between Watts and VA and the difference between DC and AC.. IN a DC circuit Watts and VA are identical but in ac VA times power factor = watts and it is rare for power factor to be ONE (Only in a pure resitive circuit would it be one.. Light bulb (incandescent) or space heater or other heater for the most part or a fully compensated inductive/capacitive system which is very rare)


Home is where I park it.

Using your rocket science, you will note that for output of 45 amps at 14.6 volts (657w) you will need input of 9 amps x 120 volts (1080VA).

When you try to do that 1080 with a 900 peak gen, your rocket will be a damp squib.

"They" say that a Honda 1000 can "only" handle a 60 amper? They must have gone to the same rocket science school you did. A 55 amp converter with the usual 0.7 PF pulls 11 amps at 120 volts (1320VA)

"They" would be correct if the statement were about an eu2000i. A non-pf-corrected 60 amp converter in boost mode is about 50 VA short of 1600, the eu2000i's max continuous rating. (The numbers will vary a bit based on efficiency and pf values).
