The difference between power adapter and charger

      Charger usually refers to a device that converts alternating current into low-voltage direct current. It includes current-limiting and voltage-limiting control circuits which satisfy the charging characteristics. The power adapter is a power converter with voltage conversion, rectification and voltage stabilization, and the output is direct current, which can be understood as low-voltage steady-state power when the power is satisfied. Source. Now let's talk about what the power adapter is. What is a charger? What's the difference between them?
      Charger: The English name Changer, usually refers to a device that converts alternating current into low-voltage direct current. Charger is a special DC power supply for rechargeable batteries. It includes current limiting, voltage limiting and other control circuits which meet the charging characteristics. Charger is widely used in various fields, especially in the field of life is widely used in electric vehicles, flashlights and other common electrical appliances. It usually charges the battery directly, without any intermediary equipment or device.
     The process of charger is constant voltage constant current trickle flow, three stage intelligent charging. The three-stage charging theory can greatly improve the charging efficiency, shorten the charging time and prolong the battery life. The three stage charging adopts constant current charging and constant voltage charging, and then adopts floating charge to maintain and charge.
     Generally, it is divided into three stages: fast charging, charging and trickle charging.
     Fast charging stage: the battery is charged with high current to restore the battery power quickly. The charging rate can reach more than 1C. At this time, the charging voltage is low, but the charging current is limited in a certain range.
      The recharge stage: Compared with the fast charging stage, the recharge stage can also be called the slow charging stage. When the express charge phase terminates, the battery is not fully charged, but also need to add the recharge process, recharge rate generally does not exceed 0.3C, because the battery voltage after the rapid charge phase increased, so recharge phase of the charge voltage should also be increased, and constant within a certain range.
      Trickle current charging stage: In the late stage of recharge, when the temperature rises beyond the limit value or the charging current decreases to a certain value, start charging with a small current until the end of the charging to meet certain conditions.
      Power adapter: English name Adapter, the common power adapter on the market is through voltage conversion, rectification and voltage regulated power converter, the output is DC, can be understood as a low-voltage voltage regulated power supply to meet the power situation.
      Power adapters are widely used in routers, telephone subcarriers, game consoles, language repeaters, walkmen, notebooks, mobile phones and other devices. Most power adapters can automatically detect 100~240V alternating current (50/60Hz).
      Power adapter is a small portable electronic equipment and electronics power supply conversion equipment, it puts the power supply outside, with a line connected to the host, which can reduce the size and weight of the host, only a few devices and appliances built in the host. Plug in wall and desktop. There is a nameplate on the power adapter, which marks the power, input and output voltage and current indicators, especially pay attention to the range of input voltage.
