I was afraid my laptop had died of old age. I tried a new battery, but the didn't work. Then noticed the angle of the cord at the plug. It appeared to be frayed. This cable has my laptop running like new.

Good and cheap solution instead of purchasing a new adapter

tl:dr - a handy adapter to have on your workbench and/or reuse older power bricks.This is one of those simple ideas that work out great =D These are super awesome if you do laptop repairs and you just want one "big" power brick (say from one of the older Dell docks) on your repair bench, and if you got a laptop requiring the smaller barrel plug you just keep this adapter handy.Also while many recentish laptops (say after 2018) do also accept USB-C charging, they often also still have a "legacy" small barrel charger plug, and you can use that while working on a machine to free up a USB-C port if you don't have a dock/hub that has power pass-through OR often won't negotiate to full charging wattage.

Ordered a two pack, but only one worked correctly. I contacted the seller and they promptly sent a replacement two pack; again only one worked. So I did end up with two working cables, just a took a little longer than planned.Note that the non-working cables will power the laptop as an "unknown" wattage adapter. It appears that the serial link between adapter and computer is not working. This is the same thing that happened to my OEM dell adapter cable after a few years and why I needed a replacement. See the attached images -- you can get to this screen by pressing F2 when powering up the computer.

I had to replace this product after a year of light use. Of the three new ones I received, only one fit snugly in my Dell laptop. The concept is so simple, the implementation is so flawed.
