Questions about this item

Does this 90W adapter need a specific AC power cord to work?

The package includes one DC power cord; you must supply a standard IEC C7 or C5 mains lead that matches your wall outlet.

Will the 7.9×5.5 mm three-prong tip fit my ThinkPad T420 that originally used a 92P1104 charger?

Yes — the connector size and pin layout match the 92P1104 and the T420 is listed among the compatible models.

How can I confirm the adapter is delivering 20V 4.5A after I plug it in?

The laptop charging indicator should light and the battery icon in Windows will show AC power with a charge rate near 90W.
