NShi 45W USB-C ac adapter 5V 2A 12V 2A 14.5V 2A 15V 3A 20V 2.25A black

45W USB-C replacement adapter

This NShi adapter delivers 45W through a USB-C connector and replaces the OEM units listed under part numbers 4X20M26252, 4X20M26256, 5A10K34713, 5A10K34723, 689C4, 814838-002, 815033-850, 815049-001, 81MH0006US, 81MH0007US, 848293-850 and 90XB03UN-MPW020. It suits owners of compatible laptops and USB-C devices that require a direct replacement for a lost or failed original charger. The black housing matches the typical OEM finish.

Multi-voltage output under load

The adapter negotiates five fixed voltage steps: 5V at 2A, 12V at 2A, 14.5V at 2A, 15V at 3A and 20V at 2.25A, maintaining the full 45W ceiling at the highest step. Circuit protection and stable current regulation are verified by UL, CE, FCC and RoHS certification, so sustained output remains within spec without thermal throttling or voltage droop during continuous charging sessions.

Replaces listed OEM chargers

It directly substitutes the twelve part numbers above, covering a range of USB-C laptops and peripherals that shipped with those original adapters. The jump is worth it when the original unit is damaged, lost or no longer holds a secure connection, and a certified multi-voltage replacement restores full charging speed without needing the exact brand-matched SKU. Buyers whose devices demand a proprietary barrel connector or a higher wattage than 45W cannot use this adapter.
