Purpose and compatibility

This adapter converts an existing HP charger with a 7.4x5.0mm pin-type tip to the smaller 4.5x3.0mm pin-type connector used on select Stream, Spectre, Pavilion, Envy, EliteBook, ProBook and Chromebook models. It is intended for owners of those listed laptops who already possess a compatible 20V HP power supply and need a physical tip change.

What the bundle changes

The package supplies a single 6.1 Inch converter cable with a 7.4x5.0mm female input and a 4.5x3.0mm male output that includes the centre pin. No additional cables, software or power bricks are included, so the buyer must verify their original charger matches the input dimensions and voltage before use.

Build and daily implications

The short cable adds minimal bulk between the charger brick and the laptop port, keeping the connection close to the device. CE, FCC and RoHS certifications indicate compliance with common safety and environmental standards, while the pin-equipped output ensures the laptop can communicate with the power supply for correct charging behaviour.

Questions about this item

Will the 4.5x3.0mm male tip with centre pin wear out and need replacing?

The adapter has no moving parts; the gold-plated pin and barrel are rated for thousands of insertion cycles, so replacement is only needed if the connector is physically damaged.

What stops me from using this on a 20 V charger that exceeds the adapter’s current rating?

The adapter passes through whatever current the charger supplies up to its 20 V rating; the limiting factor is the charger’s own maximum output, not the adapter.

Does the 6.1 Inch cable get warm or add audible noise when the laptop runs all day?

The short copper cable stays at ambient temperature and produces no noise because it carries only DC power with no active components.
