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.
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

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.

Finally got around to getting the Pulsar PG2000is on the Oscilloscope.
Perfect clean Sine waveform (as good as my Honda Inverter generator)

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

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.

One final Note on Pulsar Generators.
I have a number of generators ranging from 6250Watt Briggs and Stratton powered units to HarborFreight units and Honda Units.
This Pulsar Generator is one of my favorites. It is feature packed, has a USB outlet and all the bells and whistles of the units costing over twice as much.
It is quiet, start on first or second pull every time and runs smooth.
It is also VERY well built inside.
Provided the problem I was having was just because of one rogue appliance, it cranks out power exactly as advertised.
In addition, their Customer Service is responsive and very helpful. They were prepared to replace the generator for me with return shipping paid by them
I can highly recommend Pulsar Generators.

A final question.......
Has anyone ever heard of a situation such as the following?
Suppose you have a small device plugged into the DC outlet on the generator......
Is there any known circuitry inside a portable Inverter Generator that might sense that something is connected to the 12vDC port and then limit the output to the AC outlets?
I did initially have a small 12vDC device plugged in when I was having the issue in the OP. But I have no idea if that could cause the generator to reduce it's available output to the AC outlets.

I'll be testing that same small portable heater today with standard AC from a home wall socket to see what the VA and watts are that the portable generator could not handle.
|07-27-2019 09:28 AM|
Thanks for the suggestion.
I did the tests checking the VA as suggested with various appliances connected. Most times the Watts was essentially equal to VA.
That said, it may have been one appliance (A small, 1500Watt portable heater) that was causing the problem after all. Without that particular appliance connected the generator was able to run a 1550Watt / VA load.
With one caveat ......I'll mention below.
