Power Output and Connector

This AC adapter delivers 20 volts at 2.25 amps for a total of 45 watts. It uses a 4.0 millimetre by 1.7 millimetre barrel connector. The unit accepts 100 to 240 volt input at 50 to 60 hertz for worldwide use. A foldable plug makes it compact for travel.

It fits a range of IdeaPad models including the 100S, 110, 330S, 310, 320 and 510 series. Yoga 710, Flex 4 and Flex 5 devices are also supported along with Chromebook N22. Buyers with laptops that require a different voltage, amperage or connector size should look at something else.

Decisive Specification

Questions about this item

Does the 4.0 mm × 1.7 mm barrel connector carry the full 45 W at 20 V 2.25 A?

Yes, the 4.0 mm × 1.7 mm tip delivers the rated 20 V 2.25 A for 45 W output.

What clearance does the foldable-plug body need behind a wall socket?

The foldable pins lie flat, so the adapter sits close to the wall and only needs a few millimetres of depth behind the outlet.

How do I attach the supplied AC cable to the adapter brick?

Plug the IEC C7 figure-8 end of the cable firmly into the brick’s recessed inlet until it clicks; the pins alone do not lock.
