Protection circuit board (PCB) as a power management system is to move the power of the brain, through a complex circuit design, intelligent and efficient prov ides powerful protection for the safe operation of the power supply for the entire mobile. With a healthy heart must be highly intelligent brain to govern all aspects of the coordination of power bank performance. PCB protection circuit board to be responsible for the the mobile power conversion efficiency and stability of various security mechanisms as well as the output effect, its workmanship design directly determines the quality of mobile power output.
Mobile power did not qualify for protection circuit board in addition to easy to damage the charging load equipment, more likely to cause danger of fire and explosion, etc.? That we, as consumers, should what discriminating circuit board is good or bad?
Protection circuit boards must be qualified as a mobile power overvoltage, overcharge, over-discharge, overcurrent, overheating and short-circuit protection of six layers of basic protection functions and the qualified protection circuit boards must be able to effectively enhance the energy conversion rate and thus reduce the charging and discharging process in power consumption, the qualified protection circuit boards must be able to provide stable large input and output current. If the the battery performance conversion rate is lower than 80% or less, means moving the power line losses, batteries heat, there are security risks.
Therefore, only when a mobile power supply PCB protection circuit board using good workmanship and design, excellent quality batteries for use at the same time, the quality of this mobile power to get a guarantee.
