HP laptop charger 65W 45W

This AC adapter supplies 19.5 V at up to 3.33 A for a rated 65 W, and also supports 45 W at 2.3 A. It is built for HP notebooks that use the blue-tip barrel connector. The unit is new and intended as a direct replacement for the original power supply.

Blue tip 4.5 x 3.0 mm connector

The barrel plug measures 4.5 mm outer diameter by 3.0 mm inner diameter, a size HP calls the Smart Blue Tip. Only laptops with this exact jack will mate securely; other HP models with different tip dimensions cannot use this adapter. Input voltage ranges from 100 V to 240 V at 50 Hz to 60 Hz.

65 W rated output

The single figure that decides fit is the 65 W maximum output with 19.5 V 3.33 A delivery. If the target laptop requires more than 65 W, or a different voltage, this adapter will not meet the power demand. Buyers whose devices need a higher-wattage supply or an alternative connector type should select a different unit.

Questions about this item

Should I pick the 65 W or 45 W rating for my HP laptop?

The adapter delivers 19.5 V at 3.33 A for 65 W and automatically supports 19.5 V at 2.3 A for 45 W, so it covers both power levels with the same blue tip.

What does the 65 W rating mean when the charger is plugged into my notebook?

It means the unit can supply up to 19.5 V at 3.33 A continuously, giving enough headroom for charging while you work on a compatible HP EliteBook, ProBook, Pavilion or Chromebook.

Does the 4.5 x 3.0 mm blue tip limit the power I can draw?

The blue tip is rated for both 65 W and 45 W output, so the connector itself does not cap the power below what the adapter is designed to deliver.
