45W AC Adapter for Lenovo Ideapad

This 45W AC adapter supplies 20V at 2.25A for a wide range of Lenovo Ideapad models including the 100, 110, 310, 320, 510, 520, 710 and 720 series. It matches original part numbers such as ADP-45DW and ADL45WCC. Buyers who need a higher wattage unit or a different connector size should look elsewhere.

Plug-in replacement with 4.0×1.7mm tip

The barrel connector measures 4.0mm outer diameter and 1.7mm inner diameter, matching the port on compatible Ideapad laptops. Installation is a direct swap: connect the AC cable, plug the tip into the laptop and power on. The most common issue is ordering this adapter for an Ideapad 100S 11.6" model, which uses a different connector and will not fit.

20V 2.25A output confirms compatibility

The critical specification is the DC output of 20V at 2.25A, delivering 45W. If the original charger shows the same voltage and amperage, this unit will work; if the laptop requires a different voltage or current rating, this adapter is not suitable.

Questions about this item

How can I verify the adapter is delivering 20V 2.25A to my Ideapad 320-15ISK after connecting it?

The laptop should show a charging indicator and the battery percentage will rise; a multimeter on the 4.0×1.7 mm tip should read 20 V DC under load.

What items are included in the package and what must I source separately?

The box contains the 45 W adapter with fixed 4.0×1.7 mm DC cable; an AC mains lead for your region is not included and must be purchased separately.

Which connector size matches the Ideapad 510-15ISK and 720S-14IKB models listed?

Both series use the 4.0 mm outer / 1.7 mm inner diameter barrel, so the single 45 W 20V 2.25A version supplied fits all listed models.
