Having owned a couple of types of Chinese generators I can give me 2 cents with unbiased honesty
They work well, as long as you remember to change the oil every 50hrs or 6months.
The first one we didn't, lasted 12 months. The 2nd one we do, still going 3 yrs later.
Don't forget to factor in a 20m extension cord, power board and weatherproof power cable joiner/enclosure.
If it is just for yourself in the field get the smaller one, quieter, lighter.
