Review on π 4 Pack USB to DC 5V Power Supply Cable - 3ft USB to 5.5mm 2.1mm Barrel Jack Male Charger Cord for Laptop, Notebook, HUB Splitter, Router, LED Lights, USB Speaker by Lauren Williams
A unique cable for a unique project!
Ever had a low power device that doesn't use USB but uses a cylindrical power connector instead? A recent project of mine had this requirement as I wanted to power a small 5 port ethernet switch from a USB charger. Once I knew the right keg size, I found these cables at Revain and ordered them straight away. I have to say they work like a charm and I highly recommend them for powering small, low power devices!
- Portability for use and carrying. 4 packs of DC 5 volt 55*21 to USB power cord can meet the charging needs of most different devices at home or office, making life more convenient.
