Universal Lenovo charger

This 65-watt AC adapter powers a wide range of IdeaPad 3, Flex and Yoga laptops that use the round barrel connector. It accepts 100 to 240 volt input for worldwide travel use and carries UL safety certification. The unit replaces lost or damaged original chargers for compatible models. It is designed for owners who need a reliable spare or replacement power supply.

Steady 65-watt delivery

The adapter provides a continuous 20 volt, 3.25 amp output under sustained load rather than a brief peak rating. It also safely powers 45-watt IdeaPad models without over-voltage risk. UL certification confirms the unit meets strict thermal and electrical safety limits during extended operation. This makes it suitable for all-day charging while the laptop is in active use.

Replaces 45-watt and 65-watt bricks

The single adapter covers both 45-watt and 65-watt original power supplies, reducing the number of spare units a household or IT department must stock. It is not for USB-C charging models or laptops requiring higher wattage than 65 watts. The jump is worth it when the original brick fails or a second charger is needed for a different location. Compatibility spans IdeaPad 3, Flex and Yoga series listed in the specifications.

What must I already have on my laptop for this charger to connect?

Your Ideapad needs the round barrel power connector used on models such as the 3-14, 3-15, 3-17, S340, S145, Flex 5, Yoga 710 or V14.

Will this 65 W brick safely charge my older 45 W Ideapad 320 or 330?

Yes — the adapter supports both 65 W and 45 W systems, automatically providing the correct power for 320, 320S, 330 and 330S models.
