45W AC Adapter for Asus ZenBook UX21E, UX31E & Transformer Book
Power your slim Asus device with precision. This 45W (19V 2.37A) power supply is the definitive match for Asus ultra-portables requiring the specialized 3.0mm micro-connector. It is fully backwards compatible with 33W (1.75A) models, providing extra power headroom for faster charging and cooler operation on your ZenBook or Transformer Book Chi.
Measurement Required: The 3.0mm Micro-Tip
This adapter uses the ultra-slim 3.0mm x 1.1mm connector. This is smaller than the standard 4.0mm plug. It is specifically required for ZenBook UX21E and UX31E models. If your charging port is exceptionally thin, this is the correct factory replacement.

- Seamless Transformer Support: Engineered for the power-sipping requirements of the Transformer Book T200TA, T300FA, and T300 Chi series.
- Optimized Amperage: Delivers 2.37A for quick battery replenishment while remaining safe for 1.75A (33W) devices.
