Asus 45 W USB-C charger for Chromebook Flip Zenbook

This 45 W USB-C AC adapter supplies 20 V at up to 2.25 A and covers the 5 V 3 A, 9 V 3 A and 15 V 3 A profiles used by Asus Chromebook, Flip and Zenbook models. It replaces the original ADP-45EW B unit and carries no separate MPN. The brick is black and terminates in a USB-C plug. Buyers who need a higher wattage unit or a barrel-tip connector cannot use this adapter.

Plug-in USB-C installation no tools required

Connection is a simple USB-C insertion; no screws, cables or software are involved. The most common issue is selecting a charger with insufficient power for the laptop model, which results in slow charging or no charge under load. Verify the laptop’s original adapter rating before ordering. A loose or damaged USB-C port on the laptop will also prevent reliable contact.

Check laptop model matches the listed compatible

Confirm the device appears in the compatible model list, which includes HP Spectre x2 12 and 13 series, Spectre x360 13, Elite x2 1012 G1, Pavilion x2 10 and 12 series, Pro Tablet 608 G1 and x2 210 detachables. Cross-reference the original part numbers 815049-001 or 815033-850. This adapter will not fit laptops that require a barrel jack or a different USB-C power profile.

Questions about this item

How can I verify the adapter is delivering the correct 20V output after I plug it in?

The USB-C connector negotiates power delivery profiles of 5V/3A, 9V/3A, 15V/3A and 20V/2.25A; your laptop will show it is charging at 45W max when the 20V rail is active.

What comes in the box and do I need to buy a separate cable?

The package contains the 45W USB-C AC adapter unit only; a compatible USB-C charging cable must be purchased separately if you do not already have one.

Which output profile should I select for an ASUS Chromebook Flip or Zenbook that requires 45W?

Choose the 20V/2.25A profile — it provides the full 45W rating listed for compatible ASUS Chromebook, Flip and Zenbook models.
