HP Blue Tip AC Adapter

This 65 W AC adapter replaces the original charger for compatible HP Pavilion, Envy, ProBook and EliteBook laptops. It delivers up to 19.5 V at 3.33 A and also supports 45 W models that draw 19.5 V at 2.31 A. The blue tip connector measures 4.5 x 3.0 mm. Built-in protections include overload, over-temperature, over-current, over-voltage and short-circuit safeguards. CE safety certification is included.

Input voltage and connector constraints

The unit accepts 100-240 V at 50-60 Hz for worldwide mains use. Output is fixed at 19.5 V with a maximum of 3.33 A, so it cannot supply higher voltages or currents required by some larger workstations. Only devices fitted with the 4.5 x 3.0 mm blue tip barrel jack can be connected. Polarity and pin dimensions must match the original charger exactly.

Blue tip 4.5 x 3.0 mm connector

The single specification that decides fit is the blue tip connector sized at 4.5 x 3.0 mm. If the laptop uses a different tip diameter, pin length or centre-positive arrangement, this adapter will not connect or charge. Buyers who need a different connector size or a higher wattage output must select another model.
