33 W 19 V AC adapter for ASUS Taichi and VivoBook

This 33 W AC adapter delivers 19 V at 1.75 A for compatible ASUS Taichi and VivoBook models. It replaces part numbers ADP-40TH A, EXA1206CH, 0A001-00330100 and ADP-33AW A. The unit accepts 100-240 V input for worldwide use. Buyers needing higher wattage or a different voltage for other laptops should look elsewhere.

Check connector size and model compatibility

Verify that your laptop uses a 4.0 mm × 1.35 mm barrel connector before ordering. Confirm your exact model appears in the supported list such as Taichi 21-DH51, Taichi 21-DH71, VivoBook X201E series, X202E series, Q200E or F201E series. Using an adapter with the wrong plug or polarity can damage the device.

Worldwide input voltage and direct replacement

The 100-240 V 50-60 Hz input lets you power the laptop in different regions without a separate voltage converter. Supplying the specified 19 V 1.75 A output restores normal charging and operation for the listed ASUS models. No additional software or cables are included with this adapter.

Questions about this item

Does the 33 W 19 V 1.75 A adapter come with a mains cable or only the brick and 4.0 mm × 1.35 mm tip?

The package includes the adapter brick with fixed 4.0 mm × 1.35 mm connector; a standard IEC C7 or C5 mains lead for 100–240 V input must be purchased separately if not already owned.

My Taichi 21-DH51 needs ADP-40TH A — will this 33 W unit work or do I need a higher-wattage version?

This 33 W unit matches the listed replacement part numbers ADP-40TH A, EXA1206CH and 0A001-00330100, so it is the correct rating for the Taichi 21-DH51.

Will the 1.75 A output sustain full CPU load on an 11.6-inch Taichi without throttling?

The adapter delivers the specified 19 V 1.75 A (33 W) continuously, matching the original power budget for the Taichi 21-DH51 and listed VivoBook models.
