Power

Question

Hi,

I recently purchased a Dell Inspiron 16 plus 7640. I thought it had a usb-c port so that I could connect a usb-c sdd to it. However, i find that the usb-c port is used by the 130w power supply (which has a usb-c connector)! All is not lost though. It still has a Power Adaptor Port. I have contacted DELL technical support and they tried to sell me a dock which i dont think i need. Has anyone found an adaptor into which i can plug my 130w usb-c charger with a (male) 4.5mm jack on the other end? Apparently, Dell don't do one, but I have seen one on Amazon, but it is only rated at 100w (Bewinner 100W PD Charge Converter Fast Charging Adapter for HP Laptop, USB C Female to 4.5mmx3.0mm Laptop Charging Adapter Female Type C to Male DC 4.5 X 3.0mm: Amazon.co.uk: Computers & Accessories).

Anyone please have any ideas whether this will work, or i really do need to buy another charger?

Thanks

Ivan

The Dell adapter completes a charge circuit that almost certainly will preclude using a third party adapter.

There is an OEM adapter that will do the job, and it's not that expensive (use the part number to search the UK for it).

@ejn63​ Hi, thanks for your comment. i would rather not get another charger, if i might be able to just get a cable?

Be careful to understand your seller's return policy -- I suspect what you'll end up with is an adapter that will power the system but will not charge the battery. I can guarantee you an adapter that's designed for an HP will never charge the battery in a Dell system.

You can try this USB-C to 4.5mm adapter at your own risk.  It's rated for 20v.
