19 V 2.1 A adapter for HP 27EA monitor
This 40 W AC switching adapter supplies 19 V at 2.1 A through a 5.5×2.5 mm barrel plug. It replaces the ADS-40NP-19-1 19040E unit originally shipped with the HP 27-inch LED LCD monitor. The package includes the adapter and a detachable power cord.
Continuous 40 W delivery under load
The adapter maintains its rated 40 W output during extended monitor operation without relying on short-term peak capacity. CE certification confirms compliance with European safety and electromagnetic-compatibility requirements for continuous use. Input circuitry accepts 100-240 V at 50-60 Hz for worldwide mains compatibility.
Fixed 19 V barrel-connector interface
Output voltage and current are not adjustable; the unit only serves devices that require exactly 19 V at up to 2.1 A. The 5.5 mm outer and 2.5 mm inner diameter plug limits compatibility to matching barrel jacks. Buyers needing a different voltage, higher current or an alternative connector type must choose another model.

Questions about this item
Does the 40 W adapter run hot or make noise when powering the HP 27EA monitor all day?
The unit is a sealed switching supply with no fan, so it stays silent and only warms slightly under the 2.1 A load of the 27-inch display.
What must I already have for this adapter to work with my HP 27EA?
You need a wall outlet that accepts the included EU, US, UK or AU power cord and a monitor with a 5.5 × 2.5 mm DC jack — the adapter plugs straight in.
Will this 19 V 2.1 A supply work if I keep an older HP monitor that also uses a 5.5 mm barrel plug?
Yes, provided the older monitor requires 19 V at up to 2.1 A and uses the same 5.5 × 2.5 mm centre-positive connector.
