Ruth's sister 7.4×5.0 Female to 4.5×3.0 Male Elbow internal power cable

Connector conversion for Dell and HP

This adapter cable converts a 7.4×5.0 mm female barrel jack to a 4.5×3.0 mm male elbow plug with a centre pin. It lets an existing Dell or HP power supply feed a laptop that requires the smaller connector. The elbow shape routes the cable close to the chassis. No other devices are supported by this specific tip combination.

Pure copper core under continuous draw

The conductor uses a pure copper core rated for first-class workmanship. Copper’s low resistivity keeps voltage drop minimal while the brick supplies steady current during long charging sessions. The elbow housing holds the pins firmly so the contact resistance does not rise when the cable is bent repeatedly. Heat stays low enough that the insulation remains stable over extended use.

Black finish with reinforced elbow strain relief

A black PVC jacket covers the cable and the moulded elbow joint. The right-angle plug reduces leverage on the laptop socket when the unit sits on a desk or is carried in a bag. The centre pin on the male side engages the laptop’s detection circuit so the charger negotiates the correct voltage. Build quality is aimed at daily connect and disconnect cycles without the tip loosening.
