The principle of mobile phone solar charger
use efficiency. The efficiency of use includes two aspects: solar panel conversion efficiency and secondary conversion efficiency. The conversion efficiency of solar panels, as the name implies, refers to the efficiency of light energy conversion into electricity; and the secondary conversion efficiency refers to the efficiency of light energy stored in the battery after being converted into electrical energy.
solar charger accessories. This problem is often overlooked by many users, but can not be ignored. There are bad suppliers in the market for the price advantage and configuration of inferior accessories, such as AC charger (Common name AC adapter), AC charger with IC protection circuit or no IC protection circuit two. Unprotected IC AC charger not only charge current is small, the charging time is long and poor, and the hidden trouble.
control circuit and protection circuit. The current solar cell phone charger product is very complex, it is inside the protection circuit and control circuit may be simple design, or poor compatibility, easy to fill the phone or reduce the phone and battery life. So the design of the control circuit and the protection circuit are very important.
battery quality and capacity. Battery capacity is generally 1.2 times the cell phone battery. Solar built-in lithium battery discharge to the mobile phone and other digital products, energy conversion process will have energy loss, the conversion rate is generally 80% -90%, the battery is so solar power is enough for your cell phone, so big battery can you The phone battery is full. The quality of the battery is also related to the life of the solar charger.
The principle of solar mobile phone charger is to convert solar energy into electrical energy stored in the solar cell phone charger tool. Built-in battery, the need to charge the phone, the solar cell phone charger in the battery output power to the phone charge.
