What this adapter powers

This 65W AC adapter supplies 20V at 3.25A through a 4.0mm by 1.7mm round tip. It is built for Lenovo Yoga, Flex and IdeaPad models such as the Yoga 510, 520, 530, 710, 720s, Flex 4, IdeaPad 310, 320, 330, 510s and V330.

Installing the charger

The unit ships with a 1 metre power cord and non-retail packaging. Plug the cord into the adapter, insert the round tip firmly into the laptop's DC jack and connect to a wall outlet; the only common issue is using a tip with the wrong outer or inner diameter.

Capacity and headroom

Rated at 65W, the adapter comfortably runs the listed ultraportables and mainstream 14 to 15 inch laptops under normal workloads. It will not support larger gaming or workstation models that require higher wattage or a different connector.

Questions about this item

How can I confirm the adapter is delivering the correct 20V 3.25A output after connecting it?

The laptop charging indicator should light up and the battery icon in the OS must show it is charging; a multimeter on the barrel tip can verify 20 V under load.

What comes in the box and what must I supply myself?

The package includes the 65 W AC adapter and a 1 metre mains lead; no extra cables or tips are required for the listed Lenovo models.

Which tip size matches my Lenovo Yoga or IdeaPad — the 4.0 mm or another?

This unit has a 4.0 mm outer and 1.7 mm inner diameter round tip; check your original charger for the same dimensions before ordering.
