Laptop power adapter is the device used in computer laptop to convert A. C to D. C. Different kind of power adapter for computer have different output voltages. Output voltage differ according to the designing of a computer.
Laptop computer use DC power, laptop adapter used to convert AC voltage from the source of power such as electricity and convert to DC power voltage that is used to laptop computer.
NOTE
Each AC power adapter has different and specific power rating.
THERE ARE SEVERAL KINDS OF LAPTOP POWER ADAPTER
1. AC power adapter.
Used to convert AC voltage from the source to DC voltage.
2. DC power adapter.
This kind of power adapter produces direct DC voltage and supply direct to computer laptop.
3. Universal power adapter.
Universal adapters have very high advantages because they have several values of output voltages and the computer user can choose according to the types of laptop input voltages.
DIFFERENT VALUES OF OUTPUT VOLTAGES
1. 10 voltage output power. (mostly mini computer)
2. 14 voltage (late mac book laptops ).
3. 18 voltage.
4. 18.5 voltage (HP, Toshiba, acer, Lenovo )
5. 19 voltage (most of H.P and TOSHIBA laptops).
6. 19.5 voltage (mostly of dell laptops).
7. 20.5 voltage.
OTHER NAMES FOR LAPTOP ADAPTER
1. AC/DC ADAPTER.
2. LAPTOP POWER SUPPLY.
3. LAPTOP CHARGER.
4. AC/DC POWER SUPPLY.
