Questions about this item

Will the 7.9mm x 5.5mm connector fit my older ThinkPad T420 and X220 models?

Yes, the adapter lists T420, T420S, T420i, X220 and many other T and X series models as compatible.

How can I confirm the 90W 20V 4.5A output is stable after plugging it in?

The unit includes short-circuit, overload and over-temperature protection; the laptop should charge without shutting down or showing power warnings.

Does the box include a mains lead or only the black adapter brick with 7.9mm x 5.5mm tip?

The product is the AC adapter itself; a compatible mains cable for your region must be purchased separately.
