How to Choose the Right ASUS Zenbook Charger
1. Identify Your Exact Zenbook Model
Check the complete model number on your laptop or in its system information. A product described only as an ASUS Zenbook charger may not be compatible with every Zenbook model.
2. Match the Adapter Part Number
Compare the part number printed on your original charger with the replacement listing. For example, the products in this collection include the ADP-45EW B and ADP-90RE B adapter models.
3. Check Voltage, Current, and Wattage
Match the output specifications required by your laptop. The 45W ADP-45EW B listing includes a 20V 2.25A profile, while the 90W ADP-90RE B listing includes a 20V 4.5A profile. Choose a charger based on your laptop's requirements rather than wattage alone.
4. Confirm USB-C Charging Support
A USB-C connector does not automatically mean that a laptop supports charging through that port. Confirm USB-C power input support and the required charging protocol for your specific Zenbook model.
5. Check the Product Listing Before Ordering
Review the complete compatibility list, adapter part number, output specifications, package contents, and warranty information shown on the individual product page.
