Solar mobile charger quality lies in three aspects: firstly, the use efficiency. Use efficiency includes two aspects: the conversion efficiency of solar panels and secondary efficiency. The conversion efficiency of solar panels, just as its name implies is refers to the light into electrical efficiency, And second conversion efficiency is refers to the light into electrical energy conversion in stored in the battery, the efficiency. Secondly, quality and capacity of the battery. The capacity of the battery is your cell phone battery 1.2 times. So the solar power is enough of your mobile phone use, so large battery can make you phone batteries. But the quality of battery for solar battery life. Thirdly, the control circuit and the protection circuit. Now on the market of product solar mobile charger is very complex, him protection circuit and control circuit is simple in design, or may, easy filling compatibility mobile phones or bad shorter and battery life. So the control circuit and the protection circuit design is very important. Solar mobile charger can only be used when emergency can't depend entirely on it for mobile phones, digital products to achieve complete to electricize, general mobile phone chargers have need of solar panels than 0.7 W.
From the price to quality the good and bad are intermingled.
A good solar charger, considering using efficiency and battery and circuit design problems, from the technology uses takes larger costs. Apparently cheap solar charger can hard to do this. According to the comprehensive investigation of solar charger the retail price of solar charger lower than 20$ generally difficult to meet the expected level or to consumers.
Advice should have certain brand prestige product.
