Compatible HP All-in-One Power Supply
This 90W AC adapter replaces the original charger for HP 21z Touch, 19xt Windows 7 and 21t Windows 7 Touch All-in-One PCs including the 19-2235t model. It delivers 19V at 4.74A to match the OEM power requirements for these specific systems.
Included Power Cord Enables Immediate Use
The bundled mains cable removes the need to source a separate IEC lead so the adapter works straight from a wall socket. A built-in smart chip communicates with the HP hardware to confirm correct voltage and polarity before full power is applied.
100–240V Input Limits Global Portability
The wide-range input accepts 50Hz or 60Hz mains supplies between 100V and 240V, letting the unit operate worldwide with only a plug adapter. It cannot charge devices that require a different output voltage or a higher wattage than 90W.

Questions about this item
Will the 19 V 4.74 A output brick need replacing after a few years?
The adapter is built with safeguards against incorrect voltage, short circuit and internal overheating, and it carries a three-year worry-free warranty from the manufacturer.
What limits continuous use of this 90 W supply?
The unit is rated for 19 V at 4.74 A, so sustained loads above 90 W will trip its protection circuits before any component overheats.
How much heat or fan noise does the adapter produce when running all day?
It has no fan and relies on passive cooling; the built-in overheating safeguard keeps temperatures in check during 24-hour operation.
