SKU CH-P6EF-0RVHJ

A 90 W 20 V 4.5 A USB square-tip charger compatible with numerous Lenovo ThinkPad, IdeaPad, Yoga and Flex models and matching multiple OEM part numbers

  • 90 W output powers demanding Lenovo laptops
  • 20 V 4.5 A delivery matches original adapter specs

  • USB square-tip connector fits listed ThinkPad and IdeaPad models

90 W Square-Tip USB Adapter

This 90 W AC adapter delivers 20 V at 4.5 A through a USB square-tip connector. It accepts 100–240 V 50–60 Hz mains input and terminates in a three-prong US power cord. The unit replaces Lenovo part numbers such as ADLX90NCC3A, PA-1900-081 and 45N0237. It ships new with the adapter and cord included.

For Lenovo Ultrabook and Yoga Owners

The charger fits ThinkPad X1 Carbon, T440, X240, E440, E540, Edge E431, E531, S431, T431s and IdeaPad Yoga 11, 11s, 13, 2 Pro plus Flex 14, 15, 15D models. It also covers G410, G500, G505, G510, G700, B5400, S210, S500, S510p, U430, U430p, U530 Touch and S1 series. Buyers whose laptops require a round barrel tip or a higher wattage brick should look elsewhere.

Build Integration

The square-tip plug mates directly with the charging port on the listed ultrabooks, eliminating the need for a separate barrel-to-USB dongle. The 100–240 V input works on international mains with only a plug adapter, so the same brick serves travel and desk duty. The three-prong cord provides a grounded connection without occupying a second outlet strip socket.

Questions about this item

Does the square-tip USB connector on this 90 W 20 V 4.5 A adapter fit the charging port on my ThinkPad X1 Carbon?

Yes, the square-tip USB connector is the correct size for the X1 Carbon and the other listed ThinkPad and IdeaPad models.

Can I keep using my existing US three-prong AC power cord with this replacement adapter?

The package includes a new US three-prong cord, but the adapter inlet is a standard C6 socket, so your existing cord will also work.

How can I confirm the charger is delivering the rated 20 V 4.5 A output after I plug it in?

The laptop’s battery indicator should show charging, and a USB-C PD meter placed in-line will read 20 V at up to 4.5 A under load.
