Type-c USB 5V 3A Integrated Charge And Discharge Module 3.7V 4.2V Power Board Charge Discharge Protection Lithium Battery Boost

High-concerned chemical : none Package : SMD is_d : Yes Dissipation Power : Integrated Charge And Discharge Module Supply Voltage : 5V 3A Application : MOBILE PHONE Type : Switch Brand Name : Gaqqee Origin : Mainland China Condition : New Operating Temperature : 0-50C

Features: 1.4 LED power display is more intuitive 2. This product is a lithium battery charging and discharging integrated motherboard, suitable for all types of 3.7V lithium batteries, polymer batteries nominal 3.7V, full 4.2V 3.The product in the design, materials, PCB technology up and down enough effort, so that the module can be in a very small volume to do a very considerable parameters and features 4.TYPE-C port support input/output charging cell phone, support for charging and discharging at the same time, automatic detection of cell phone insertion and extraction 5. Stable performance, the product has over-current discharge protection, battery over-voltage, over-charging, over-discharge protection and so on. Parameter: 3A (battery side) high efficiency charging 2.4A maximum output current Output fixed normally open 5V Standby power consumption less than 150μA Module terminal definition: Type-C interface: module 5V power supply input interface, as the output of the power supply without agreement USBA interface: module 5V output interface, can be charged to cell phones and other equipment power supply 5V: module 5V output positive welding point (can also be used as input wiring) -5V: module 5V output negative welding point (can also be used as input wiring) B+: Module connects to the positive terminal of the battery. B-: Module connects to the negative terminal of the battery. Attention: The above two module buttons only in the LED indicator lights out when the role of the indicator lights open, and can not control the input and output or close the LED indicator lights. Caution: 1. Battery connected to the reverse will burn the board, so be sure to pay attention. Need to weld to normal use, welding, please discharge static electricity on the soldering iron and the human body first. 2. Module in the no-load standby state, in order to optimize power consumption and detect whether there is connected to the input voltage will drop to 4.8V or so and will be every few seconds back up to 5V voltage, to detect whether the load is accessed. 3. The wiring must be soldered, the line should be as thick and short as possible, the center can not add a switch. 4. The more power the module uses, the closer the current is to the maximum current. Heat will be greater, use attention to heat dissipation. Frequently asked questions and answers: 1. Can the module be used as a UPS or seamless switching between input and output? A: When the input is disconnected, the input to the output there will be a short switching time, which is determined by the circuitry 2. Can the module be used as a UPS or can the input and output be switched seamlessly? A: The input and output of the same port, that is, when the input voltage, the output is the same voltage output. Just make sure the input power is enough. Avoid instability. 3. What is the role of the button? A: The keys are only used to display the voltage. No other function, the module in standby mode under the power display lamp will go out, to see the power through this button. 4. Can the C port output charge the cell phone? A: Recommended for cell phone charging with USB port, are compatible. If you use the C port, Huawei, Xiaomi and other cell phones can be, but need to agree on the chip of the phone such as Apple and Samsung's part of the model can not. The main reason is that these models need to recognize the chip to start charging (the module is a power output), so it is recommended to use the USB port is no problem. Package include: Charging and discharging module *1 label:yes
