45W 20V AC Adapter for Lenovo IdeaPad

This 45-watt power supply delivers 20 volts at 2.25 amps through a 4.0 by 1.7 millimetre barrel connector. It accepts 100 to 240 volt AC input at 50 or 60 hertz for worldwide use. The unit is brand new and built to replace the original Lenovo ADL45WCC, PA-1450-55LL and ADP-45DW B GX20L23044 adapters. It suits owners of compatible IdeaPad, Yoga and Flex laptops who need a direct replacement charger.

45W capacity and connector fit

The adapter comfortably powers the listed 45-watt IdeaPad models including the 310, 320, 320S, 330S, 510, 520, 710S, 100, 110 and 120S series. It also supports Yoga 710 11, 14 and 15 inch models plus Flex 4, 5 and 6 series such as the Flex 4-1435, Flex 4-1470 and Flex 4-1570. It will not fit devices requiring the USB square yellow tip or higher 65-watt and 90-watt 20-volt 3.25-amp units, so buyers needing more power must look elsewhere.

Power cord included for immediate use

A mains power cord is bundled so the charger works straight from the wall socket without a separate cable purchase. No software, drivers or extra accessories are supplied or required. The package provides the complete charging solution for the compatible laptops listed above.

Questions about this item

Will the 4.0 x 1.7 mm connector on this 45 W adapter fit my older IdeaPad 320-15IKB that originally used a 65 W unit?

No. The 4.0 x 1.7 mm tip is designed for 45 W models only. The 65 W and 90 W Lenovo chargers use a different USB square yellow tip connector, so this adapter will not physically fit or supply the higher wattage your older machine expects.

How can I confirm the adapter is delivering the correct 20 V 2.25 A output after I plug it in?

The brick has no built-in display. Use a USB-C power meter or a multimeter on the barrel plug to verify 20 V under load; the laptop’s battery icon should show charging and the LED on the tip (if present) will light when power flows.

Does the package include a UK mains lead or only the brick with the 4.0 x 1.7 mm cable?

Only the adapter brick with the fixed 4.0 x 1.7 mm DC cable is supplied. A region-specific AC mains cord (IEC C7 figure-8 or C5 cloverleaf depending on the brick inlet) must be purchased separately.
