The solar folding bag is a new type of high-tech solar product with intelligent adjustment function, which can adjust different output voltages and currents. It can charge different charging products, such as MP3, MP4, PDA, digital cameras, mobile phones and other products. The solar folding bag is small in size, high in capacity and long in service life. It is suitable for business trips, tourism, long-distance travel by car and ship, field operations and students' backup power supply. It has the characteristics of safety protection, good compatibility, large capacity, small size and long service life. Let's talk about how to choose a solar folding bag.
The key to the quality of a solar folding bag lies in:
1
Efficiency of use. The conversion efficiency of a solar panel, as the name implies, refers to the efficiency of converting light energy into electrical energy; the conversion rate of a general solar panel is only 14-16%, and the charging speed is slow; a good conversion rate can reach about 23%.
2
Constant voltage output, control circuit and protection circuit. The current solar folding bag products on the market are very complex. The protection circuit and control circuit in it may be simply designed, or have poor compatibility, which can easily damage the mobile phone or shorten the service life of the mobile phone and battery. Therefore, the design of the control circuit and the protection circuit are very important.
3
Solar charger accessories. This issue is often overlooked by many users, but it is an aspect that cannot be ignored. There are bad suppliers in the market who configure inferior accessories for price advantages. You should pay special attention when purchasing solar chargers.
Types of solar folding bags
1. Solar folding bags generally cover between 5W and 300W. They are too large to be produced, and generally do not require such large solar panels for outdoor activities.
2. Solar folding bags can be produced according to customer requirements in customized sizes, wattage, different types of solar panels, folding numbers, output interfaces, output lines, etc.
3. Solar folding bags can be designed for customers, board making services, various forms of LOGO requirements, etc.
4. Solar folding bags can customize circuit boards for customers or provide standard circuit boards such as single USB, dual USB, single USB + DC output regulator or linear output
