Compatible IdeaPad and Chromebook models

This 65 W AC adapter fits Lenovo IdeaPad 110, 110s, 120, 120s, 130s and Flex 4, 5, 6 models with 14 or 15 inch screens. It also supports Chromebook N22, N23 and N42 devices. The 4.0 × 1.7 mm barrel connector matches the charging port on these laptops.

Replaces 45 W and 65 W Lenovo chargers

The adapter delivers 20 V at 3.25 A for 65 W output and is backwards compatible with systems that originally shipped with a 20 V 2.25 A 45 W unit. It accepts 100–240 V AC input at 50 or 60 Hz for worldwide use. The upgrade is worthwhile when the original charger is lost, damaged or no longer holds a stable charge.

Build integration and protection

The package includes the power adapter and a detachable AC power cable for immediate desktop or travel deployment. Internal circuitry provides over-voltage, over-current and short-circuit protection to safeguard the laptop during charging. The rugged housing resists impact from daily transport. Buyers needing USB-C Power Delivery or a different barrel size should look elsewhere.
