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 Dante Obong

This is a much thicker and higher quality cable than those that usually come with the product. I bought a barrel cable "M" and "N". "Tip is center positive and inner diameter (ID): 2.5. Tip "M" is center positive and ID: 2.1. The "N" tip seems to fit more of my electronic devices. It should be noted that all types of tips that include the alphabet, each with a different length, inner diameter and outer diameter. Very, very confusing, and what looks good sometimes doesn't work. MAKE SURE IT IS CENTERED.
