Which laptop power supply should you buy?

Question

Power Supply

You need to buy a new laptop power supply. Can I choose any one with the necessary parameters (voltage, current, plug size) or do I need to take exactly the same model as it was?
If you can, please send a link to a PSU that is suitable for a Lenovo G580 laptop (PSU parameters 20v, 4.5A, 5.5x2.5). The PSU model was PA-1900-56LC.

Answer 1

any, suitable for the parameters, BP.
By the way, if you are going to take a new block, take a closer look at the universal ones (with removable / replaceable plugs for various manufacturers).
