Review on 🔌 XINYUWIN USB Type-A Male to 5.5mm x 2.1mm Barrel 5V DC Power Cable - Compatible with Laptop, Notebook, HUB Splitter, Router, LED Lights, USB Speaker by Rick Rownd

This adapter set is versatile. It's like a multi-tool or a USB-powered pocket knife. One of the main things I use it for is running an HDMI recorder, which is typically used by your TV and runs on AC power connected to a mirrorless camera powered by a power bank. When you combine this cable/adapter with a USB power bank, it can do many portable things that require an outlet (of course it has to be something that only requires 5V 2A to work).
