It takes 20 minutes to charge 5000mah with 12W solar panel.
It also depends on the charger you use to charge the power bank. If the charger power is relatively high, the speed will be slightly faster and it will take more than ten minutes to fully charge a bar. If the charging power of the charger you are using is relatively low, it will typically take up to half an hour to fully charge a bar, so choose the power of your charger and see if it works for how long.
The charging principle of mobile solar power is to convert the sun's energy into electric energy and store it in the battery of mobile solar power. When the mobile phone does not have enough power, the mobile solar power supplies the battery power to the mobile phone. However, mobile solar energy can only be used in the event of agency, and cell phone charging cannot depend entirely on mobile solar power. If you need to use a solar power bank to charge your mobile phone for a long time in daily life, it is recommended to choose a solar panel of more than 0.7W, otherwise it will not have a charging effect. obvious load.
First of all, please note that when charging the mobile power under strong light, do not delay charging it for at least 8 hours before the battery is fully charged. As we all know, it is still a bit difficult to get uninterrupted direct sunlight for more than eight hours a day.
Second, do not place the mobile power supply in a car where the temperature is high, otherwise the battery life will be shortened. Try not to charge the mobile power by shining sunlight through the glass,because of the effect. is not obvious.
Finally, be sure to charge the mobile power under strong light and do not use chemicals to wipe the product.
Although solar power banks are no longer a new term nowadays, they have their own advantages over lithium battery power banks and are widely used by a large number of mobile phone users. However, mobile solar power supplies still mainly rely on novelty to attract people's attention, and the advantages are not obvious from a current practical and technical point of view, the quality is very average, the charging speed is slow and power conversion rate. is weak. Therefore, smartphone users are recommended to choose high-quality, fast-charging and safe brand power banks such as Sino to charge their phones forentire battery life.
