How does the mobile power work?
When the use of mobile power for mobile phones and other electronic products, digital equipment charging, the internal inverter output circuit board to the lithium battery voltage increased to 5.0V DC voltage output,
When charging the mobile power, the maximum charge voltage of the lithium battery set controlled by the protective plate is limited to 4.2V;
In fact, the mobile power inside the general includes a group of lithium batteries with a protective plate and an inverter output circuit board, plus a set of control switches and input and output interfaces.
when the lithium battery discharge to the protection voltage, the lithium battery protection board action
