　　How much does Baoyuan know about mobile power charging

　　In fact, the principle of mobile power supply is very simple. It is a portable charger that integrates power supply and charging functions, usually consisting of lithium cells or dry batteries as storage units. The quality of a mobile power supply depends heavily on its battery cell and protective board. Generally speaking, the lifespan of lithium polymer cells is much longer than that of lithium-ion batteries, and they are also relatively safe, usually lasting for two to three years. The indicator of a protective board is its conversion rate. A good protective board has a conversion rate of up to 90% or even more, while a regular board has a conversion rate of around 80%. The difference is even lower, and the line loss is significant. It is recommended not to use it.

　　Mobile power sources are highly sought after by the public due to their mobility, versatility, and convenience. However, its security is of utmost concern. In the market where there is a mix of good and bad, when choosing a mobile power supply, it is still more important to consider its cost-effectiveness. In addition, when purchasing a mobile power supply, one should also pay attention to whether it has protective measures such as short circuit, overcharging, over discharge, constant current, and constant voltage. Of course, high-performance power management technology is also essential.

　　Only by comprehensively considering these factors can we choose a more suitable and high-quality mobile power supply.
