A power adapter is a device that converts alternating current into direct current. It is used to supply power for notebook computers, smart phones and other electronic devices that require DC power to work.

On the other hand, the charger is a device used to charge the battery. It is designed to provide direct current to the battery and then store it for later use.

The main difference between the power adapter and the charger is that the power adapter is used to power the device, while the charger is used to charge the battery.

As for why there is no universal power adapter or charger, it is because different devices have different power requirements. For example, laptops may need higher voltage and current than smartphones, so they need different adapters. In addition, different manufacturers may use different connectors for their devices, so it is difficult to create a universal adapter or charger for all devices.
