Compatible Power Adapter

The ROLADA BRJ65B200325 is a 65W AC adapter built for Lenovo IdeaPad 3 and Flex 5 laptops requiring a 20V 3.25A input. It serves as a direct replacement or a spare unit for travel. The barrel connector uses a 4.0mm x 1.7mm round tip with a black centre pin. It is not a USB-C charger and will not fit yellow square tips.

Fixed Output Limits

The brick delivers a steady 20V at up to 3.25A for a maximum of 65W. Input accepts 100-240V at 50-60Hz for worldwide mains use. The fixed voltage means it cannot charge devices that need a different voltage rail. The barrel interface carries no data and cannot negotiate higher power profiles.

Replaces 45W And 65W Units

This adapter safely replaces both 45W (20V 2.25A) and 65W original chargers thanks to backward compatibility. The laptop draws only the current it requires. Buyers needing a USB-C power source or a tip size other than 4.0mm x 1.7mm should look elsewhere. The detachable AC cord eases packing but does not change the output specification.

Questions about this item

Is this 65W charger the right one for my Lenovo IdeaPad 3 or Flex 5 that originally came with a 45W adapter?

Yes, the BRJ65B200325 delivers 20V 3.25A 65W and is backward compatible with 45W 20V 2.25A models. The laptop draws only the amperage it needs.

What does the 65W rating actually provide when the adapter is plugged into my laptop?

It supplies a steady 20V at up to 3.25A, giving 65W maximum. If your machine requires 45W it will draw 2.25A instead, so the brick runs cooler and lasts longer.

Does the 4.0mm barrel connector work with every Lenovo charging port?

The tip measures 4.0mm x 1.7mm with a black centre pin. It fits IdeaPad 3 and Flex 5 models that use this exact barrel size; it is not USB-C and does not fit yellow square-tip ports.
