How to choose your right portable adapter?
(This laptop has)
V = An input Voltage of 19.5V.
AC or DC – DC as indicated by the symbol.
mAh/A – consumes 3.34A to 4.62A of current.
Once you have this key data you are ready to start looking for an adapter.
Choosing the right adapter specs.
The general rule is to match the V and equal or beat the mAh, so if you are choosing an AC adapter to make sure you check the following,
The adapter output V matches the rated input V of the device.
The adapter output is greater or equal to the devices rated mAh or A.
The plug fits into your device and has the correct polarity.
Usually, all of this info is on the adapter sticker, remember you are always looking for the output V and mAh or A.

Reading the polarity of the connector
(There is also the less popular center negative (-) connector.)

(Typical low voltage adapter sizes.)
Choosing the plug
Hopefully you have the size of the devices plug and can just check the adapters measurements, there are two measurements for these types of connectors.- OD – Outer diameter of the plug.
- ID – Inner diameter of the plug.
If you are measuring you need the diameter of the center pin for the (ID) and the inner diameter of the port (OD).
