Replacement AC Adapter for Lenovo Laptops

This 65W 20V 3.25A power supply replaces original chargers for a wide range of Lenovo IdeaPad and Flex models including the IdeaPad 3 5 Flex 5 4 6 11 14 15 series. It delivers 65W output and is also compatible with 45W 20V 2.25A requirements. The unit accepts AC 100-240V 50/60Hz input for worldwide use. A 4.0 x 1.7 mm barrel connector fits the listed devices.

Thermals Noise and Power Draw

The adapter operates at 65W maximum output with 20V 3.25A delivery during normal charging. Input voltage range of 100-240V allows stable operation across different mains supplies. No active cooling fan is present so acoustic output is minimal in typical use. Power draw scales with the connected laptop's demand up to the rated limit.

Build Quality Connectors and Daily Use

The barrel plug measures 4.0 x 1.7 mm and mates with compatible Lenovo ports on models such as Flex 4 5 6 series and IdeaPad 330 330s 530s S530 S130 Yoga 710 lines. A standard IEC C7 or C5 mains lead connects the brick to the wall outlet. The unit is supplied new and carries the listed part number compatibilities including ADL45WCC ADP-45DW B ADL45WCH ADL45WCG ADLX65CLGU2A ADLX65CCGC2A PA-1450-55LL PA-1450-55LZ PA-1450-55LS PA-1450-55LR PA-1450-55LN PA-1450-55LK PA-1450-55LI PA-1450-55LG GX20L23044 GX20K11838 GX20L29355 SA10M42786.

Questions about this item

How do I install the 4.0 x 1.7 mm connector correctly and what is the common mistake?

Align the 4.0 x 1.7 mm barrel plug with the laptop's DC jack and push straight in until fully seated; the common mistake is inserting it at an angle which can bend the centre pin.

What maintenance or replacement will this 65W 20V 3.25A AC adapter need later?

The detachable AC mains cable may wear at the strain relief; the adapter itself is sealed and has no user-serviceable parts, so replace the whole unit if output voltage drops under load.

What limit appears first when this charger runs at 65W continuously?

Thermal protection triggers first; sustained 65W output raises the case temperature until the internal safety circuit reduces power or shuts down until it cools.
