First, let’s take a look at the internal structure of 20w apple charger. Mobile phone chargers are mainly composed of transformers, rectifiers, filters, voltage regulators and other components. When the charger is plugged into an AC outlet, the AC power is stepped down by a transformer and then converted into DC power by a rectifier. Next, the DC power goes through a filter to remove the ripple signal, and finally a voltage regulator stabilizes the voltage within a range suitable for charging mobile phones. In this way, we can connect iphone usb charger to the mobile phone for charging.


In addition to basic charging functions, modern iphone charger with plug also have some advanced functions. The first is full of self-stop function. When the mobile phone battery is full, the charger will automatically stop supplying power to the mobile phone to avoid overcharging and protect the life and safety of the mobile phone battery. In addition, fast chargers are also a major feature of modern samsung 45 watt charger. Compared with traditional ordinary chargers, fast charger can charge mobile phones with higher current and voltage, greatly shortening the charging time. Under normal circumstances, a 18w apple charger can fully charge a mobile phone battery within 1-3 hours, which is very convenient and practical.


In order to ensure the safety of users, multi car charger are also equipped with overload, overcurrent and other protection devices. When the current exceeds the safety range set by the charger, these protection devices will automatically disconnect the circuit to prevent accidents caused by excessive current. In addition, in order to ensure the safety and stability of the mobile phone charging process, the 18 watt fast charger also needs to have good heat dissipation performance. The heat dissipation system inside the charger can quickly dissipate the generated heat to prevent malfunctions or fires caused by overheating. Therefore, it is very important to choose a regular brand and quality-assured 30w charger.
