What is a solar charger?
I believe there is a thing that you often see and even use in your daily life. It brings us a lot of conveniences, especially when mobile phones become more and more important in our life. Imagine when you go out and your cell phone is dead, do you become anxious? With it, you can get rid of this anxiety. I think you’ve already guessed what it is. Yes, it’s a solar charger.
The solar charger is a device that converts solar energy into electric energy, which is stored in the battery. It is generally composed of three parts: solar panel, storage battery and voltage regulator. Solar charger can charge your mobile phone, digital camera, PDA and other products. High power solar charger can even power your notebook.
It has the characteristics of safety protection, good compatibility, large capacity, small size, long service life and high-cost performance. It is suitable for your business trip, tourism, long-distance travel, field operation and other environments.
How does a solar charger work？
The principle of the solar charger is to convert the light energy into electric energy in the sun and store it in the built-in battery through the control circuit. It can also directly charge your mobile phone or other electronic digital products with the electric energy generated by the light energy, but it must be determined according to the luminosity of the sunlight, electronic can be converted from AC to DC and stored in the built-in battery through the control circuit.
How to distinguish the quality of solar charger?
- Efficiency
The utilization efficiency includes two aspects: the conversion efficiency of solar panels and the secondary conversion efficiency. The conversion efficiency of solar panels refers to the conversion efficiency of light energy into electric energy; The secondary conversion efficiency refers to the efficiency of light energy stored in the battery after it is converted into electric energy.
- The quality and capacity of the battery
Solar built-in lithium battery discharge to mobile phones and other digital products will be energy loss in the process of energy conversion, the conversion rate is generally 80% – 90%. So the capacity of the battery needs to be 1.2 times that of your mobile phone battery. Only in this way can the battery fully charge your mobile phone battery. In addition, the quality of the battery is also related to the service life of the solar charger.
- Control circuit and protection circuit
The current solar charger products on the market are very complex. Its protection circuit and control circuit may be simple in design or poor incompatibility. It is easy to damage the mobile phone or shorten the service life of the mobile phone and battery. So the design of the control circuit and protection circuit is very important.
- Solar charger accessories
This problem is very important, but it is often ignored by many users. AC charger with IC protection circuit or without IC protection circuit two. The AC charger without protection IC not only has low charging current, long charging time and poor effect, but also has all hidden dangers. When choosing solar charger, you should pay special attention to whether AC charger has circuit IC protection.
What should we pay attention to when using solar charger?
- Do not put the solar charger in the car in summer (the temperature in the car is too high), which will affect the service life of the battery.
- Please don’t charge the solar charger through the glass. The charging effect is poor.
- Charging must be carried out under strong light. The solar charger will light up in weak light, but this only means that light is detected, not charging (such as under indoor lighting). Therefore, do not charge under weak light.
- As the power content of each solar charger is not consistent when it is delivered from the factory, the initial charging or discharging time will be different.
- Please do not use corrosive solution to wipe the solar charger to avoid damage.
- Do not put the solar charger into the fire to avoid explosion
