Chinese brands are good if you don't run AC, fridge or other sensitive appliances. But if you do, buy some renowed brand like honda, yamaha, hundai.
The best chinese brands are: Jasco, Loncin, Magma, Lifan, and many more... I have been using Magma for 10 years and still going Ma.sha.Allah... The great thing about chinese brands is that the complete spare engine and dynamo can be replaced by a brand new unit, and all other spare parts are available and very cheap.
