Question about Ekström 2000i

This Generator product in China, it Chinese name is QL2000i. which is OEM product for this brand. Factory is https://www.qinglongpower.com/. Taizhou Qinglong Machinery & Electric Co., Ltd.

"Normal operation" is not a definite statement, as the unit burns more or less petrol depending on the consumers connected (= load = wattage consumption) (which can also be heard in the engine noise). This generator has a tank capacity of 4 litres, which is enough for about 4.5 hours of continuous operation under full load (2 kW). And regarding manufacturing: Ekström is a Swedish brand name, so I think the products are made in Sweden.
