Please focus on the “OUTPUT” section of the standard power adapter.
For example, let’s say it says “19V 3.42A”. You can calculate the
“Wattage” using the “Volts” and “Amperes”. In this case, 19 * 3.42 =
64.98, meaning the output power of the power adapter is approximately
65W.
When replacing a power adapter, the “Voltage” must be the same.
The Toshiba adapter in the photo is 19 * 6.3 = 119.7, so its output
power is approximately 120W.
For products with the same voltage, a higher wattage means the adapter
has more power headroom (a larger capacity).
Next, please check the connector shape. Generally, the center is
positive (+) and the sleeve is negative (-). If the connector dimensions
match as well, you should be able to connect it. (Outer diameter:
5.5 mm / Inner diameter: 2.5 mm). Beyond that, please proceed at your
own risk.
