lutian 3.5va lt3600
https://www./lutian-3.5kva-generator-with-key-starter-lt3600e-black-5544401.html

mainly used evenings, to power 200l fridge, led tv, laptop, 3bulbs and a rechargable fan.

price is not important.
i was inclined to the lutian based on the fact there are no fakes, has a key starter and it will give room for other gadgets - e.g. a small ac/washing machine later. However run time per fuel load is very important to me. 15L for 12hrs compares badly to the sumec which is 5.5L for 9hrs. daily usage, and the running costs will climb steeply.

Which is better? I dont know if the runtimes stated are cast in stone. Should i go for the lutian, maybe running it with low loads will make it consume less OR the sumec and manage how many appliances i switch on?

Thanks.

I have a sumec
carries a deep freezer
fridge
3Hd TV at a go
3 ceiling fans
light bulbs and a times
washing machine,pumping machine,blender or micro wave although I must outbthe refrigerators.
And the fuel consumption is very low.
Its a very durable gen provided you purchase the original.

was it the same model/same output rating as the one i described above?
thanks
