45 W Blue-Tip AC Adapter

This 45 W AcBel adapter delivers 19.5 V at 2.31 A through a 4.5 mm by 3.0 mm blue connector. It is built for HP Stream, Pavilion, Envy, Spectre and ZBook models that use the listed part numbers. The unit includes a US mains plug and carries UL safety certification.

Replaces OEM chargers in compatible HP laptops

The adapter substitutes for HP part numbers such as 741727-001, 740015-002, 740015-004 and 719309-003. It fits the barrel port on supported notebooks and frees the original charger for travel or backup use. No extra cables or converters are required.

Runs cool and quiet at rated load

The 45 W design operates without a fan, so it adds no audible noise to a workspace. Power draw at the wall matches the 45 W output rating under normal charging conditions. Heat stays low enough for desk or lap use during typical sessions.

Questions about this item

At what point does the 45W output limit the adapter during continuous use?

The adapter delivers a fixed 19.5V at 2.31A for a total of 45W. If the laptop demands more than 45W the adapter cannot supply it and may shut down or throttle.

Does the adapter become noisy or hot when powering a Stream 14 all day?

The unit has no fan, so it runs silently. Normal warmth is expected at 45W continuous load, but the UL safety test confirms it stays within safe temperature limits.

Which HP part numbers must the laptop already use for this blue-tip adapter to work?

The laptop must use one of the listed HP part numbers such as 741727-001, 740015-002, 740015-004, 719309-003, 721092-001, 854054-001, 854054-002 or 854054-003.
