Charger: The English name Charger, usually refers to a device that converts AC power into low-voltage DC power. The charger is a special DC power supply for rechargeable batteries. It includes current limiting, voltage limiting and other controls that meet the charging characteristics. Circuit. Switching power adapter
Input voltage range: It is the range of the mains voltage allowed by the power adapter, and it is also the mains voltage range that guarantees the normal power supply of the power adapter. The larger the range, the better the adaptability. The input voltage range should be AC 100～240V, special reminder: it Divided into working conditions under two voltage environments: AC 110V and AC 220V. The correct test method is to switch the voltage test when the power adapter stops working.
For charger products, some people call wall plug-in Chinese-certified power adapters as power adapters, switching power supplies, and transformers. Cell phones and laptops can be charged when they are out of power. These are the simplest. The current society is a fast-paced society. The current mobile power supply promotes fast and high-efficiency charging, which greatly saves time for citizens. And now all chargers on the market have high-efficiency charging. Effect
Generally, plug-in power adapters are generally used below 36W. The characteristic of this power adapter is that it does not require AC wires, which saves costs and saves space, and does not require a countertop space for placing the power supply. It is also safer to directly plug into the plug-in board. There are a few power adapters below 36W that use the desktop type. This is generally because the product is far away from the AC plug-in board or because the power adapter is large in size and heavier, or The power adapter is heavy.
