Fits most laptops.

Can be set for 19-20V DC
Input: 100 – 230 V ~ 50/60 Hz 1.1 A
Maximum output current: 4.5-4.7 A

Note:
If the wattage of your laptop is lower than 90W (Watts), this will not damage your computer, the computer only takes the amount it needs.
That is, if your computer only requires 45W (Watt), then both 90W and 120W will work. If, however, your computer requires 100W, then a 90W will not be powerful enough.
It is only if you connect an ex 19V (Volt) adapter to a 15V (Volt) that you risk damaging the computer.
Note Also be sure to measure your connector so it fits.
