90W AC Adapter for HP Laptops

This 90-watt AC adapter delivers 19 volts at 4.74 amps and accepts 100 to 240 volt input at 50 or 60 hertz. It uses a 7.4 by 5.0 millimetre barrel connector and ships with a three-prong US mains cord. The unit is compatible with a wide range of HP EliteBook, ProBook, Pavilion, G-series and Compaq Presario notebooks.

Sustained-load behaviour

The adapter is rated for continuous 90-watt output and also supports 18.5-volt, 19.5-volt, 65-watt and 45-watt loads, so it can power the original charger specification and lower-wattage models without shutting down. Overheating and short-circuit protection circuits are built in to maintain stable operation during extended charging sessions.

Thermals, noise and power draw

The supply runs from 100 to 240 volt mains at up to 2.5 amps and has no moving parts, so it operates silently. Protection features limit temperature rise and prevent damage from overloads, keeping the brick cool to the touch in normal indoor use.

Questions about this item

Does the 90W adapter run hot or make noise when it powers a laptop all day?

The unit includes overheating and short-circuit protection, and it accepts 100-240V 50/60Hz input so it operates within normal thermal limits for a 90W supply.

What must I already own to use this 7.4*5.0mm tip with my HP notebook?

You need a compatible HP or Compaq laptop that uses a 7.4 mm by 5.0 mm barrel connector and requires 19V at up to 4.74A.

Will this 19V 4.74A charger work safely alongside an older 65W or 45W brick I still have?

The adapter is rated 90W and is also compatible with 18.5V and 19.5V systems at 65W and 45W, so it can replace those lower-wattage units.
