There are dozens of generators of various brands and models. How should consumers buy them?

First move: three certificates should be complete. A qualified generator should have production license, product certificate and trademark registration certificate. The product certificate shall include the certificate of the whole unit, the certificate of internal combustion engine and the certificate of generator.

The second move: see whether the seller is professional. Now the business of generators is good, and all kinds of miscellaneous shops have started generator business. However, consumers had better go to a special seller of mechanical and electrical products to buy, so that after-sales service can be easily guaranteed. Those shops that sell temporary "guest" generators no longer sell generators after the peak season, which brings hidden dangers to after-sales service.

Third move: the price should be moderate. Due to different brands, the prices of various generators with the same power also vary greatly. For example, some brands of a 2 kW gasoline generator cost 1580 yuan, while some brands of generators with the same power cost 1850 yuan. Many consumers buy wherever they like, which is wrong. There is indeed an appropriate price difference between various brands, but if the price is too low, you have to consider - this product is not shoddy, right? Because, at present, the transparency of generator price has been very high. Although "high quality and low price" is what everyone wants, it is more that the quality of goods is directly proportional to the price. Moreover, the safety of electricity must be absolutely guaranteed.

The fourth move: the power should be suitable. If you have a series of household appliances such as refrigerator, air conditioner and TV at home, you must buy a generator of about 5 ~ 8 kW. For families without air conditioning and with a series of other household appliances, a generator of about 2 kW is generally enough. If only lighting is needed, a generator with a power of 650 ~ 800 watts can solve the problem.
