45W replacement charger for Lenovo notebooks

This 45 watt power adapter delivers 20 volts at 2.25 amps through a 4.0 by 1.7 millimetre connector. It is built as a direct replacement for the original Lenovo supply used across numerous IdeaPad, Yoga, Flex and Chromebook models. The unit accepts 100 to 240 volt input at 50 to 60 hertz for worldwide use.

Check connector size and voltage before ordering

Verify that your laptop requires a 4.0 by 1.7 millimetre barrel tip and 20 volt output at 2.25 amps. Confirm the original part number matches PA-1450-55LU or ADP-45DW C to ensure correct polarity and fit. The charger is not suitable for devices needing a different tip diameter or higher wattage.

Slim design fits tight bags and frees a bulky brick

The compact housing reduces bulk in a carry case and leaves more room for other accessories. It plugs directly into a standard mains lead without an extra power block on the floor. The 45 watt rating supports everyday charging for compatible ultraportable and mainstream Lenovo systems.

Questions about this item

What comes in the box and do I need to buy a mains lead separately?

The package includes the 45 W power adapter with a fixed 4.0 × 1.7 mm DC plug; a detachable AC cord for the 100–240 V inlet is not included and must be sourced separately.

My Lenovo model appears several times in the compatibility list — how do I pick the right one?

Match the exact model number on your laptop’s base label to the list (for example Yoga 710‑14IKB, IdeaPad 330‑15IKB, Miix 520‑12IKB); the adapter’s 20 V 2.25 A output and 4.0 × 1.7 mm tip must match the original PA‑1450‑55LU or ADP‑45DW specification.

Will the 45 W rating actually run and charge my Yoga 710 under load?

Yes — the unit delivers a steady 20 V at 2.25 A (45 W), which is the factory rating for the listed Yoga and IdeaPad models, so it will power the system and charge the battery simultaneously.
