Werewolf transformed my old gadgets into USB-C powered ones

This seems like a really cool device from a company called Werewolf. As the article details, they make a little $8 programmable USB-C power adapter, called the VFLEX, that you can get barrel plug adapters for to power older devices that use barrel plugs. The article discusses some caveats, such as not every USB-C power supply supporting every voltage a device may need. But you can plug the VFLEX into your power adapters (and battery banks) and create a local database of available voltages. Then when you want to power a specific device the app will guide you through which power adapters are compatible with it. I have no affiliation with the company, but after reading about the VFLEX it seems like a neat option to power some older devices I have.
