Importance of circuit board protection system for mobile power supply
Security is more important than the embodiment of the core. Many manufacturers shouted "safety" slogans, but they could not say why. In fact, the protection mechanism of mobile power supply, mostly by the circuit board is responsible for. In general, a good circuit board has three protection functions, that is, overcharge protection, over discharge protection, over-current protection. If the core is compared to a storage battery, the circuit board is like a warehouse keeper, strictly controlling the input and output of the current. Mobile power output current is not constant, that is, the current is too large or the output current is not saturated (too small), will cause great damage to the battery. So buy a mobile power supply, not just listen to the business how to blow, we must recognize the flicker behind is still flicker!
Circuit protection of mobile power supply
Although the circuit board is mounted inside the mobile power, can not see the specific structure directly, but the circuit board is to control the security attributes of mobile power "brain", related to the user experience and security attributes can not be negligent.
There are a lot of people use the reaction of mobile power for charging the mobile phone, mobile phone appears unresponsive, touch disorders and black screen problem. This is because some of the poor quality of mobile power using a simple circuit board, discharge instability led to excessive current burn bad phone. Some brands of mobile power circuit board is relatively precise, with multiple protection functions, the reasonable use of the risk coefficient is zero. So, what are the benefits of circuit protection?
葡京牛牛赌场 The first is the compatibility of the difference in the scope of application - not every mobile power supply can give your phone a reasonable charge.
