Solar charger as one of the best equipment for outdoor travel, then we must pay attention to its three characteristics:

    1. Surface material

    Solar charger is one of the products commonly used outdoors. In addition to being portable, the material it uses must be waterproof, wear resistant and fall resistant. Because the outdoor conditions are very bad, and what may be encountered, so the solar charger must be anti-fall anti-build, the use of surface material for internal protection. So the selection of surface material is very important for the solar charger.

    2. Solar cells

    At present, solar cells in the market are mainly made of silicon. The difference between monocrystalline silicon and polycrystalline silicon mainly lies in the photoelectric conversion rate. The conversion rate of monocrystalline silicon is higher than that of polycrystalline silicon, while that of polycrystalline silicon is higher than that of amorphous silicon. The same material of the cell, the larger the area of the solar panel, the greater the conversion power will be, the output current will be relatively larger. As a frequent outdoor use of consumers, must buy a large area of solar charger, because its conversion power is higher than the ordinary solar charger.

    3. Intelligent voltage stabilization and intelligent restart

    The solar charger can convert solar energy into electricity in direct sunlight, but once the battery is shaded, it will power off immediately. This is the biggest drawback of solar chargers. So outdoors travel, portable solar charger is carried with the function of the intelligent voltage regulation and intelligent restart, at the same time it reflects the importance of these two function, when the sun can be regulated automatically, and once broken sunshine can  automatically restart, this not only is more efficient to worry also.

    When you buy a solar charger, be sure to choose it in accordance with your common scenes, because in different scenes, the functions of the solar charger are different. For this new type of product, we must choose carefully.
