From units I've had, that DC output is typically unregulated voltage, and is really intended just for charging batteries, not so much for running cigarette-lighter style loads.

Agreed.


This particular generator actually has a Cigarette lighter socket as it's 12v DC receptacle.
I would prefer it had a Honda style plug because I find that when the unit is running, the vibration tends to shake the connection loose repeatedly.
This may be the only poor design choice of this unit.
If Pulsar changed it to a plug and actually provided a small DC battery charging cable with the unit it would be a very big plus.

I doubt now that the DC connection had anything to do with it. It was the faulty small portable heater.

Finally got around to getting the Pulsar PG2000is on the Oscilloscope.


Results?
BEAUTIFUL!
Perfect clean Sine waveform (as good as my Honda Inverter generator)

I went on an email spree and emailed pretty much all the Chinese manufacturers asking who makes their generator engines. Pulsar responded by saying it was Ducar. I don't know who Ducar is, so perhaps they are one of the better ones?? No idea.

I'm really interested in finding a review of the new WEN 56380i. I have my eye on that.

Don't know anything about the WEN generator but it seems very close in specs to the HarborFreight Predator 3500. Both have the 212cc motor.
Also, you "Can" push the Predator to a few hundred more watts, so maybe WEN is simply not expressing any margin for overload?

It's probably as good as most inexpensive Chinese made Inverter Generators I would imagine.

I would summarize to say, however, that the days of expensive, good quality Inverter generators are over (for now)
I paid $965.00 US for my Honda eu2000i generator about 10 years ago.

The Pulsar Inverter generator pictured in this thread was $320 BRAND NEW DELIVERED !
That was during an online sale. I think now they're about $100 more.
But still....

The Chinese have built millions of small engines not only for the scooter industry, but also for Honda, Yamaha and pretty much every one else so they have gained the expertise to build very reliable and yet very inexpensive motors. (something to consider from a military perspective)

Keep in mind when you buy a generator that it's not only power power output that matters, but for how long. In a disaster, you could lose not only power, but also the availability to replenish your fuel supply. So stretching your fuel supply is an important strategy.

That's why from my perspective, having several small (2000watt) generators which sip fuel very conservatively and can be paralleled is possibly favorable over one 4000watt generator.
Also, you have redundancy...two generators instead of one in case of failure. Of course, having several small generators AND a larger one is also great if the budget can manage it.

Of course, ymmv
