Questions about this item

Will the 19.5 V 6.15 A output charge my older Lenovo Y470 the same way as the original adapter?

Yes — the 19.5 V 6.15 A 120 W output matches the original specification, and the 5.5 x 2.5 mm plug fits the Y470 charging port.

How can I confirm the adapter is delivering the rated 19.5 V after I plug it in?

The laptop battery icon should show charging, and a multimeter on the barrel connector will read 19.5 V when the unit is powered.

Does the package include both the AC adapter and a mains cable for a UK socket?

The box contains one AC adapter and one power cord; the cord supplied matches the plug type selected at purchase.
