Solar chargers are solar products that use solar energy to directly charge laptops, mobile phones, digital products, etc.
Genuine 4W/5V solar charger (USB output interface) produced by GS-SOLAR - weight (138g), output current is above 600mA under normal circumstances, it can charge Nokia mobile phone with a 750mAH battery, if there is enough sunshine. Full charging only takes a few tens of minutes (at midday), less than an hour. Currently, mobile phones available in the market can be fully charged in 3 hours.
Many solar chargers currently on the market are concept products. Why do you say that? Because they're all wearing high-tech solar-powered outerwear, but it's basically a mobile power supply. Solar energy on such a chargeSolar power bank (Power Bank) is intended for decoration and does not exert the true power of solar energy. Let's take an example:
There is a 2600mA model on the market equipped with a 0.4W solar panel (the actual capacity is much smaller, many are less than half). If the solar panel wants to charge mobile power, the minimum voltage should be 3.8V for floating charging. In this way, under the standard test lighting (1000W/square meter, AM1.5), the maximum operating current is only 100mA. . If this mobile power supply, the built-in solar panel charges the battery, which takes more than 26 hours under testing conditions. In our daily living conditions, the lighting is lower than the standard test lighting, so the normal working current of the solar panel of this mobile power supply is less than 80mA, and the actual output current is even more small, usually smallgreater than 60 mA. . Therefore, the solar panel of this mobile power supply needs to be left in the sun for 44 hours to fully charge the battery. If you can get 11 hours of sunlight per day, it will take 4 consecutive days for a full charge. If you really leave it in the sun for such a long time, the mobile power supply will be significantly damaged. It is possible that the battery of this mobile power supply may explode. Therefore, the solar panel equipped with this mobile power supply is just an embellishment.
So when buying a solar charger, you should buy a real solar charger.
In the case of high outdoor power consumption, ordinary mobile power supplies cannot meet the long-term outdoor power consumption. For a long time, high power demand becomes a problem for outdoor power supply. The use of genHigh-power erators and generators to generate electricity outdoors are an old-fashioned method of power supply that is impractical, not environmentally friendly and makes a lot of noise. While the portable outdoor solar mobile power supply solves outdoor electricity consumption, it can be specifically used in outdoor entertainment electricity, outdoor high-power electronic equipment, outdoor first aid electricity, the Dianxiaoer 100 W solar panel, in the sun. It can be fully charged in 6 -8 hours and can continuously provide long-term power supply for different electricity needs. It uses photovoltaic solar energy to achieve “where there is sun, there is electricity” and to guarantee a “green, environmentally friendly and noise-free” exterior. Environment.
