ASUS Zenbook S 14 charger: what wattage to buy (UX5406)

A 100W USB-C PD charger covers every ASUS Zenbook S 14 (UX5406) and fast charges the newer UX5406AA: ASUS lists a 65W (20V / 3.25A) adapter for UX5406SA (Core Ultra 7 258V) and a 68W (20V / 3.4A) adapter for UX5406AA (Core Ultra 9 386H / 7 356H), which it calls “fast-charge capable with 100W USB-C power delivery adapter”. A UX5406SA owner can use a 65W charger.

Match & price

Full answer

ASUS USA’s tech specs for the Zenbook S 14 (UX5406) list two models. UX5406SA (Intel Core Ultra 7 258V, 72Wh battery) — “TYPE-C, 65W AC Adapter, Output: 20V DC, 3.25A, 65W”. UX5406AA (Intel Core Ultra 9 386H or Core Ultra 7 356H, 77Wh battery) — “TYPE-C, 68W Ultra mini AC Adapter, Output: 20V DC, 3.4A, 68W” with a 240W Type-C cable, and “Fast-charge capable with 100W USB-C power delivery adapter”. Both charge through 2× Thunderbolt 4 ports “with support for display / power delivery”.

So: a 100W USB-C PD charger (20V / 5A from one port, with a 5A e-marked cable) fits every Zenbook S 14 and is what ASUS names for fast charging the UX5406AA. On a UX5406SA a 65W charger matches ASUS’s own adapter. A 65W brick on a UX5406AA still charges, just slightly below ASUS’s 68W adapter. Check the model number on the label under your laptop (UX5406SA / UX5406AA) before you buy. For the regular Zenbook 14 (UX3405, 65W) see the Zenbook 14 charger page; for the Snapdragon Zenbook A14 see the Zenbook A14 charger page; for other ASUS laptops see the ASUS USB-C charger page.

What wattage to buy

What wattage to buy

  • 100W USB-C PD — ASUS says the UX5406AA is fast-charge capable with a 100W USB-C PD adapter, and 100W also covers the 65W UX5406SA. One 100W brick covers every Zenbook S 14. See 100W chargers.
  • 65W USB-C PD — the adapter ASUS lists for UX5406SA (Core Ultra 7 258V, 20V / 3.25A). See 65W chargers.
  • Under the ASUS rating — usually still charges, slower, and may not keep up while you work.
Which cable

The right cable

For 100W (20V / 5A) use a 5A (100W or 240W) e-marked USB-C to USB-C cable; a 3A (60W) cable caps charging at 60W, which is below both ASUS adapters (65W and 68W). ASUS lists a 240W Type-C cable with the UX5406AA’s 68W Ultra mini adapter. The UGREEN 65W bundle includes two 100W USB-C cables; the Apple 2 m cable is rated up to 240W. See the USB-C cable guide.
