Description

Universal Voltage Adapter

technical field

The utility model relates to the technical field of power adapters, in particular to a universal voltage adapter.

Background technique

The power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. Electronic devices such as mobile phones, tablet computers, and notebook computers used by people in daily life are equipped with their own power adapters. Each electronic product on the market is equipped with an independent power adapter, which cannot be used interchangeably. The reason is that although the input voltage is 220V, the output voltage and output current of various adapters are completely different, and most interfaces cannot be used universally. The interface is common, and casual interchange use will cause damage to the adapter to varying degrees, posing a threat to safety. The most direct problem of the non-universal power adapter is that when traveling away from home, you need to prepare a variety of adapters to charge different electronic products, which is very inconvenient to carry.
