Of course, we pay the price of the “speed ğı offered by these tools with their larger and more heavy than standard charging adapters.

Indeed, why are the adapters of fast charger, compared to standards?

The rules of physics are the primary reason for this situation.

The basic logic of rapid charge is to provide more power transfer for a short time. This depends on the power formula. For example, a standard charging adapter provides 5V/2A (10W) power, while fast charging devices can reach assets, 20V/5A (100W). This requires the components to be larger and more robust.

In rapid charge, the current or voltage is increased by increasing the power. However, the high current can lead to resistance -based heating. In order to control this temperature, the resistance of the conductors to carry the high current should be low. This requires thick copper wires and special alloys. In addition, cooling systems increase the size of the device.

The electronic circuits in the rapid charging devices have a more complex structure than the elder.

The components that control the high voltage are produced in larger sizes to avoid too much heating. In addition, these modules used for power storage and voltage transformation are physically large to withstand high power levels.

The chips that provide contact with the device and the middle of the battery cover the extra circuit area. This is another factor that causes the devices to be larger.

Of course, high power brings some risks.

Therefore, these devices have to add extra security layers to overflow defense circuits, thermal sensors and insulation equipment. The weighing and size of the increasing number of components increases naturally.

In addition, the size of the adapters is also affected by this situation, as there are 2 or 3 USB ports in a number of fast charging devices.
