The module adopts Chipsea CS32G020K8U6 main control, built-in program, which is more user-friendly than pure hardware modules.Slow rise and fall design, to prevent the instantaneous current from being too large. This module can output 5v5a9v5a12v5a15v5a and 20v6a. The 5-15v of common fast charging modules on the market can only output 3a current. actually make The power consumption is very good, which can meet the vast majority of usage scenarios. Almost all fast charging protocols on the market are supported, but if the mobile phone does not support non-original fast charging.Can't reach maximum power! The product inductance adopts imported inductance, although only 12x12mm, but the heat generation is also very low. The module uses 4 strings of lithium batteries for power supply (lithium iron phosphate batteries are strictly prohibited), and has the functions of automatic stop when full and low voltage automatic protection. But the battery pack still needs Product master: CS32G020K8U6+SC8812 Oh, the protection board, to prevent excessive current and accidents. The battery pack current should be Greater than 7a as far as possible. If the battery power is too low, it will definitely not be able to achieve the maximum output effect. At the same time, the battery will also heat up when charging. The module is bidirectional buck-boost, input 5v can also charge 4 strings of battery packs, and can output 20v when the battery pack is 12v. There are 4 m2 screw fixing holes on the module, of which the rear two with pads are input, and the 4 holes of the product must be M2 screws Precautions: 5. It is strictly forbidden to reverse the positive and negative power supply 6. It is strictly forbidden to use lithium iron phosphate battery pack or battery pack without protective plate 7. The battery pack current needs to be able to output at least 7a for a long time 8. The components on the circuit board are dense, and it is strictly forbidden to touch the chip pins or other compo
