Review on ⚡️ HiLetgo 5pcs USB 2.0 A Male to DC 5.5x2.1mm 5V DC Connector Charging Barrel Jack Power Cable - Black (Max 2.5A Power Cable, Center PIN Positive) by Dave Hock

I didn't know they existed and I didn't know they would work, but this is amazing value and allows me to set up my portable switch router perfectly for my portable NetBoot to run a Mac without external connection to diagnose ! 5/5, this allows me to even use what would normally use a 5v1a dc switch in my mobile router's USB port while charging the mobile router. If your switch only uses 5v1a or less, you can power it from the USB bus! The same goes for routers!
