4.5×3.0 mm to 5.5×2.1 mm DC adapter cable

This internal power cable converts a 4.5 mm by 3.0 mm female barrel jack to a 5.5 mm by 2.1 mm male plug. It is designed to connect compatible laptop power adapters to HP computers requiring the smaller tip diameter. The pack contains two cables for spare or dual-system use.

For HP laptops needing a 5.5×2.1 mm tip

Suitable for owners of HP laptops whose charger uses a 4.5×3.0 mm connector but whose device requires a 5.5×2.1 mm input. Not for devices that need a 5.5×2.5 mm centre pin, a different barrel diameter, or a right-angle plug orientation.

Questions about this item

What size DC power jack must my laptop have to accept the 4.5 × 3.0 mm female end of this cable?

The laptop needs a 4.5 mm outer diameter and 3.0 mm inner diameter barrel jack to mate with the female connector on this cable.

Will the 5.5 × 2.1 mm male plug on this cable fit the 5.5 × 2.5 mm tip on my existing HP power adapter?

No, the 2.1 mm centre pin is smaller than the 2.5 mm hole on that adapter, so the connection would be loose and unreliable.
