What is the laptop adapter
- 3, classification: according to the use of points (AC, such as home, office use AC are called AC; DC, such as the car, the aircraft are used DC are called DC); by the output voltage current (12V series, ASUS more commonly used, such as ASUS 12V3A; 15V series, TOSHIBA more commonly used, such as TOSHIBA 15V3A, 15V4A, 15V5A; 16V series, SONY, IBM more commonly used, such as SONY 16V4A, IBM 16V4.5A; Series, HP, such as HP 18.5V3.5A; 19V series, such as ACER 19V3.42A, TOSHIBA 19V3.42A; 19.5V series, such as DELL 19.5V3.34A, SONY 19.5V4.1A; 20V series, such as DELL 203.5A , LENOVO 20V3.25A; 24V series, such as APPLE 24V1.875A; 9.5V-24V series, such as Acharger ALS-185A35C).s

What are the types of power adapter used in notebooks?
- With the increasing popularity of notebook computers, the power requirements have increased. In addition, because the battery capacity (or density) increased, charging requirements also increased - so the laptop computer power requirements have doubled. However, larger and / or hoter power adapters are not an attractive option for millions of users who carry laptops around the world. Attractive is to have a compact, but instantly charged laptop adapter. Of course, it will not produce heat, and will not cost too much. In recent years, the development of electronic products has not increased the hope in this regard, and whether the future revolution can be achieved is still a pending issue. We also want to use a laptop adapter that can be used globally without the need for a 110/220 volt operating voltage selector switch - so the laptop adapter must be designed for truly universal line voltage operation. At the same time, regulators and OEM expectations also play a role.s
