What should I pay attention to when buying solar string lights?

1, charging should be fast. This mainly depends on its charging power. 2, choose a brand new battery for solar string lights. Because of the lack of industry standards for solar lamps and lanterns, there are many manufacturers who directly use the second-hand batteries eliminated from electric vehicles, which are used to reduce costs. Maybe the price of such a light will be very low, but really not durable. So when you buy solar string lights, make sure to see if the battery is a new battery. And the capacity of the second-hand battery will become smaller, not at all up to its labeled capacity, and will not be able to ensure sufficient light hours. 3, the level of protection should be high. Solar string lights need to be exposed to the wind, sun and rain for a long time, so protection and so on, as well as to be high enough to avoid the light into the water and dust caused by the shortening of the lamp life. Protection level is the IP level of the light, I represents dustproof, P represents waterproof, in general the higher the number the better. Of course, in addition to these basic requirements, buy solar string lights can also consider its ability to work in rainy days. The brand you mentioned does a good job on this point, they use cloud and rain intelligent adjustment system, can ensure that the continuous cloudy and rainy days can also work normally.
