myVolts 90W USB AC Adapter for Lenovo ThinkPad X1 Carbon T440 E431 IdeaPad Z510

SKU CH-R1H3-Z31Y8

90 W USB-C charger with 20 V 4.5 A output for compatible Lenovo laptops

  • Delivers 90 W output for fast charging
  • USB square connector fits compatible Lenovo models
  • 100–240 V input works worldwide
  • Replaces multiple Lenovo part numbers including 45N0236
  • Includes power cord for immediate use

90W USB AC Adapter

This 90 watt USB AC adapter replaces Lenovo part numbers including 45N0236, 45N0237 and PA-1900-081. It delivers 20V at 4.5A from a 100 to 240V input and uses a USB square connector. The package includes the power charger and a power cord.

Suits ThinkPad X1 Carbon T440 E431 and IdeaPad Z510

Buyers with the listed Lenovo models can use this as a direct replacement. It is not for laptops that require a different connector shape or a higher wattage rating. Users needing multiple simultaneous outputs should look at a different solution.

Handles 90W load with 100-240V input

The adapter comfortably powers compatible notebooks at the full 90W rating across the stated voltage range. It runs out of headroom if the connected device draws more than 4.5A at 20V or requires a proprietary barrel connector not matching the USB square plug.
