LORDWORLD 90W 20V 4.5A USB Square Tip Laptop Charger

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.
