Small 2-stroke inverter generator

[markopolo-ClassB]

I saw a small pure sine wave inverter generator at Walmart today.
2 stroke gasoline engine 44cc
digital inverter generator
800w continuous 1000w max
60dB (on web, not on box)
$250
around 18 lbs empty
I think it is a Quinglong QL1000i

The Maximum Continuous Input Power on the Progressive Dynamics converter / charger in my van is 725 watts so a 800/1000w generator could be a good match for it. I was briefly tempted to buy it as it was so small and light weight ............. but I'd have to carry it and extra gas ..........

Photos from the manufacturer - I picked these to show how small & light it is.

That's what I always hoped they would come out with, but powered by a clean burning Sterling engine.

hmmm....how many db?

Edit - answer my own question - 65 db @ 7 meters! Loud!
Like the rest of the chinese generators, it's cheap - $80 ea in bulk.

I've seen 55, 60 & 65 dB(A) noted on different sites. 65 dB(A) seem to come from manufacturer now. Huge diff between 55 db and 65 db!

There's a complaint about the noise in the remarks here: http://www.aliexpress.com/item/Smart-Po ... 59255.html

I was hoping to find a YouTube video but no luck.

Compare to:

Yamaha EF1000iS
4-stroke
900w rated 1000w max
27.9 lbs
47 dBA to 57 dBA
MSRP around $879

Honda EU1000i
4-stroke
900w rated 1000w max
29 lbs
53 dBA to 59 dBA
MSRP around $949

DW always says get the Yamaha or Honda -

I have the Yamaha and love it. Always starts and is whisper quiet. It's a good choice if you just want to run battery charger or maybe the water heater. It's only 7-8 amps. It's not much heaver than this chinese generator - think it's around 20-25 lbs.

To run the air conditioner, you have to step up to the 2000 (really only 1600 watts). It has just enough amps to run a 13,500 BTU air conditioner with a soft start.

I agree - larger genset needed for typical setups.

----------------------------------------------------

It takes roughly 50 amps DC to run the 5000 BTU A/C in my van http://www.classbforum.com/phpBB2/viewtopic.php?f=12&t=2286#p11997 not factoring in the startup surge. That's why I'm semi-interested in any combo or single unit that could produce 45a or more DC. PD converter + genset for example (combo). Alten DC genset (single).


Yamaha EF1000iS
Rated AC Output (continous) 900 Watts
47 dBA to 57 dBA
MSRP around $879.00
Weight 28 lbs
17.7" x 9.4" x 14.9"

Alten G1 http://www.altendc.com/dc-generators/ga ... rator.html
Rated max DC output 55 amps
64dB to 74dB
MSRP $1,298.00
Weight 26 lb
16.1" x 10.8" x 14.6"

Walmart genset
Rated AC Output (continous) 800 Watts
65dB
Price $250
Weight 18 lbs
12.6" x 9.8" x 13"

The Walmart generator is the smallest and lightest of the bunch but I doubt I'll buy it. I could just idle the van for similar output of the 3 units listed.

I've run a 5000 BTU Frigidaire window AC unit on my Yamaha 1000 without issue (I had one rigged up to use in my sailboat). In your case, I'd plug it in directly to the generator, and not plug your rig's shore power cord into it, as the converter would probably overwhelm the unit, drawing more total amps than available.

That's good to know - thanks. I had figured that I might have to run it through the inverter. Running it straight off the the generator is way more efficient.
