What is a Power Port?
A computer's or other electronic device's power port enables it to draw power from a wall socket and charge its battery if necessary. Batteries-free devices such as desktop computers require a power cord plugged into a power port to turn on. When a device like a laptop, which usually includes a battery, is charged, it can function as long as anything is plugged into the power port. A power port is an interface that makes it easier for electrical energy to be transferred from a source—like a battery or power supply—into a device. This can be anything like an electric car, smartphone, gaming console, or laptop. Power port designs and specs can differ significantly based on the kind of device and power needs.
This port is a specialized socket or connector made especially to supply electricity to a system or device. By acting as an interface between the device and the power source, it facilitates the flow of electrical energy needed to run the device's internal components or charge its batteries. Depending on the device they are designed for, power ports can take on a variety of shapes and sizes. They can be as basic as wall outlets or as specialized as USB ports or DC power jacks.
Functions
- The Power Port class offers electrical power connection characteristics.
- Users can compute the electrical current required by each component and manage the electrical power switching of those components using this class.

How to Use power port
- Create an inheriting component class from the Component class.
- The Power Port class is a member of the Component class, which regulates the behaviour of the component based on electrical power switches.
- Create a PowerControlUnit instance and attach the power port.
- To control the Power Port's port ID and connection, the PowerControlUnit base class contains a member of the Power Port class map.
- The Main Routine function allows users to control the power switching in their PCU, which they can create by inheriting the PowerControlUnit base class.
new PowerControlUnit(clock_gen) = pcu_;
pcu_->ConnectPort(0, 0.5, 3.3, 0.3);
- Use the associated PowerPort to create an instance of the components
clock_gen, pcu_->GetPowerPort(0), obc_ = new OnBoardComputer(1, );
- Use the PowerControlUnit to regulate the power switches.
- Users must power on the port to run the components' MainRoutine as the power switch is by default turned off.
pcu_->SetVoltage(3.3)->GetPowerPort(0);
Note: When users construct instances of the Component class and its subclasses without providing PowerPort information, a virtual power port is established. The switch state is initially ON, but no power is consumed, and the virtual port has a port ID with a negative value.
Power port for laptops
The market is filled with different laptops that require an AC adapter to be connected to a power source. Depending on the laptop manufacturer, the power connector's location may vary, although it is typically located in the back or rear corner of the device. The power brick that transforms the power signal and the wire that connects it to the power port is shown in this picture of an AC adapter. In this instance, a second power line would be connected to a wall outlet from the brick.

Power Ports for tablets and smartphones
The fast expansion of smartphones and tablets has led to the use of several power ports. Luckily, USB Type-C connectors are becoming more common in organizations. It is a power port connector found on all new Android phones and tablets and Apple iPads. Sadly, all of the newest Apple iPhones still use the Lightning connector. Through the use of a power adaptor, these connectors are connected to the wall outlet. Alternatively, these devices can be powered and charged via a computer equipped with a Thunderbolt or USB interface.

How should a power port be cleaned?
Make sure the device is unplugged from the power source before cleaning a power port. After that, you can use compressed air or a soft brush to carefully clean the port to get rid of dust and dirt. Take care not to place anything that could damage the port, including liquids or metal objects.
If my power port isn't working, what should I do?
It is best to check for problems with the power supply and the cable first if your Power Port isn't working. If things appear to be in order, the issue might be with the port itself. In this scenario, you might want to replace the port or consider seeing a specialist.
Conclusion
To transfer electrical energy for operation or charging, a power port is an essential component connecting a device to its power source. Ports can be made to last longer by keeping particles and dirt away from them, even with normal maintenance. If a power port doesn't work, try troubleshooting power supply and cable problems; replacing the port or getting professional help are possible fixes.
