65W AC adapter with foldable plug and charging indicator fits compatible Lenovo IdeaPad, Yoga, Flex, Chromebook and Miix models using a round connector
This charger supplies 65W at 20V 3.25A and also powers 45W models at 20V 2.25A. It fits IdeaPad 1 3 5 Slim 3 5 7 S340 S145 330 320 310 Flex 5 4 14 15 V14 V15 V17 laptops with a round connector. It replaces the original adapter for daily charging at home or on the move.
The foldable plug avoids scratches and saves space in a bag. A built-in charging light shows when power is flowing. The unit meets nationally recognised electronic safety standards and operates on 100-240V 50-60Hz mains worldwide. High-quality materials support reliable and durable performance.
The adapter maintains its rated 65W or 45W output during extended charging sessions without throttling. Safety circuitry protects against over-voltage over-current and short-circuit conditions throughout sustained load. It delivers consistent power for long work periods or overnight charging.

Unfold the plug fully until it clicks into the locked position, then align the round connector with the laptop's power port and insert it straight without twisting; forcing the connector at an angle can bend the pin inside the port.
Inspect the cable jacket periodically for fraying near the strain reliefs and replace the unit if the insulation is damaged; the charging indicator LED requires no maintenance but signals when the adapter is actively delivering 20V output.
The thermal protection circuit will trigger first under sustained 65W load, causing the charger to shut down until it cools; it automatically resets once the internal temperature drops to a safe level.
