Right-Angle DC Adapter Cable
This pair of right-angle cables converts a 7.4mm outer by 5.0mm inner barrel connector to a 4.5mm outer by 3.0mm inner plug with a centre pin. Both ends feature a right-angle design to reduce strain on laptop ports. The copper core construction supports power delivery for compatible notebooks. It is intended for internal power cable applications.
Suits owners of Dell or HP laptops needing
The adapter powers on Dell systems with the smaller barrel jack but will not charge the battery on those machines. Users who require battery charging from the same adapter should look elsewhere. It also does not suit devices using other barrel sizes or USB-C power delivery. Buyers needing a straight connector instead of a right-angle profile should consider a different cable.
Converts 7.4*5.0mm source to 4.5*3.0mm load
The cable handles the power-on current for compatible notebooks using the specified centre-pin connectors. It runs out when the source adapter uses a different outer or inner diameter than 7.4mm and 5.0mm. The pair provides a spare or replacement for mobile workstations. No other voltage or current ratings are provided by the manufacturer.

Questions about this item
What existing power adapter tip does the 7.4mm by 5.0mm female end of this cable need to fit?
The female connector accepts a 7.4mm outer diameter and 5.0mm inner diameter barrel tip with a centre pin, matching the output of your current charger.
Will this right-angle adapter let me charge a Dell laptop that uses a 4.5mm by 3.0mm barrel port?
The product notes state that Dell systems can only be powered on, not charged, when using this 4.5mm outer by 3.0mm inner male tip.
How can I confirm the adapter is delivering power to the laptop after connecting it?
The laptop should power on and show an external power indicator; the supplier notes charging will not occur on Dell models.
