How Portable Phone Charger Works
A portable phone charger is a battery-operated device with a control circuit, an input and output port, and a battery. It allows devices to charge without direct access to a power source. To use the power bank, plug it into an electrical outlet and fully charge it. After charging, connect your electronic device to the power bank with a USB cable.
The power bank will transmit energy to recharge your device's battery while you are away from a power source. The power bank can charge other devices by connecting them with a cable. It stores energy inside its casing, which is a rechargeable lithium-ion battery.
The primary components of a power bank are a lithium-polymer battery pack, input and output ports, a charging and discharging circuit, and a battery. A battery monitoring and protection circuit, controller, switch, and LED indicators also exist. Here is a better understanding of the key components:
-
Battery Cells: A power bank consists of rechargeable batteries with charging and discharging circuits. This indicated that the battery pack is the device's core component.
-
Input/Output Ports: Power banks include USB connections for input and output. Micro USB is primarily used for input, while Type A is for output. Moreover, the power bank can even charge your laptop if it uses Type C.
-
Circuit Protection: Charging lithium-ion batteries is one of the challenges faced. If the voltage attains a certain level, the battery temperature increases, which could eventually lead to the battery catching fire or even exploding. This might cause a significant danger to the user. Therefore, the power bank's battery pack is attached to a battery protection circuit. It continuously monitors the voltage and amperage of the battery output and input.
