When it comes to consignment, I believe everyone is familiar with it. In the process of traveling, especially if you need to take a plane, it is inconvenient to carry a lot of luggage at this time. Consignment has become the best choice. Through consignment, the burden of travel can be reduced. However, although it is convenient to check in, there are many items that cannot be checked. So, can the power adapter be checked? Let's take a look at it together!

In the past, power adapters generally used linear power supplies, which required a very bulky transformer to provide sufficient inductive reactance, so the power adapter was very bulky. Today's power adapters and chargers generally use modern electronic technology. The switching power supply technology directly rectifies the 220V AC power to obtain a signal similar to a square wave. Without the bulky transformer, the volume can naturally be made smaller.
