Review on MyVolts USB Power Cable: A Battery Alternative for Zoom H4n and H4n Pro Recorder by James Jenkins

I ran out of battery several times at concerts or meetings. No longer! I ordered and received the USB power adapter and started using it immediately. As a videographer, I'm trying to extract clear audio from event soundbars. Sometimes using a cable isn't practical, so using the H4N for direct capture ensures clear audio on video. I don't have to worry about my batteries draining, it's just less of a headache. Worth the investment.
