Review on 🔌 StarTech.com 3 ft USB to Type M Barrel 5V DC Power Cable - USB Power Cable - USB (Power Only) (M) to DC Jack 5.5 mm (M) - 3 ft - Molded - Black - USB2TYPEM by Manni Diaz

Most of our VoIP phones are 5 volt powered. When people "manage" the separation of devices and power supplies, we are often left with what appears to be an expensive paperweight. Replacing power supplies costs about $20. With these 5 cheap cables you can use [high quality] 5V USB chargers for mobile devices. They save us from wasting money. I prefer the cleanliness and current stability of Anker USB power supplies to jerky power supplies (measured, no photos).
