According to the specifications, that laptop can use a 65-watt adapter with 4.5 mm diameter barrel-type plug. In fact, you can use any Dell adapter with that size plug, as long as it outputs at least 65 watts. So, if you find a good deal on a more powerful one, or already have one from an old system, you may use it. For example, here's a 65-watt adapter from Parts-People who supply genuine Dell parts, and here is a 90-watt adapter.
Recently I purchased an "Inspiron 16 5630. The system came with the a USB-C charger. That's fine but prevents me the use of the Thunderbolt port since that's where it connects. I would like to purchase a power adapter which uses the barrel socket located on the left side of laptop, near display. I searched all over Dell.com but have been unsuccessful. Use Chat it gave me a part number of FHYND but doesn't exist. Can anyone put me on the right track to obtain the correct number and I would be most grateful.
