What this adapter powers

The Hadepa A1800 is a new 90-watt AC adapter rated at 19.5 volts and 4.62 amps. It uses a 4.5 by 3.0 millimetre blue-tip connector and accepts 100 to 240 volts at 50 or 60 hertz. The package includes the adapter and a power-supply cord.

Sustained-load behaviour

Rated for continuous 90-watt output, the unit maintains 19.5 volts at 4.62 amps during extended charging sessions. It also supports 65-watt loads at 3.33 amps, so it can power compatible notebooks without throttling when the battery and system draw full current together.

Replacement scope and when to upgrade

This adapter replaces HP part numbers 710413-001, 709986-001, 709986-002, 709986-003, 710414-001 and 709967-003 across Spectre x360, Envy, Pavilion and EliteBook models listed in the compatibility data. The jump is worth it when the original 65-watt or 90-watt supply is lost, damaged or no longer holds voltage under load. Buyers who need a different connector size or a higher wattage rating should look elsewhere.

Questions about this item

Does the 90 W Hadepa A1800 adapter run hot or make noise when used continuously?

The 90 W unit has no fan and is rated for 100-240 V 50/60 Hz input, so it operates silently; normal warmth is expected during extended use.

What must I already own to use this 4.5 mm blue-tip charger?

You need a laptop that accepts a 4.5×3.0 mm blue-tip connector at 19.5 V 4.62 A, plus a standard IEC C7 or C5 mains cord for the wall socket.

Will this 19.5 V 4.62 A adapter work with my older 65 W HP laptop that uses the same blue tip?

Yes — the manufacturer highlights confirm compatibility with 19.5 V 3.33 A 65 W models using the identical 4.5 mm blue tip.
