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

I love it! I used to use four AA batteries when recording a best quality concert with my Zoom H4n Pro, as two batteries would charge to 1/4 in about an hour (I estimated - using "meter" on Zoom) . So at break I put in a second pair of batteries, I really couldn't use this set any more "fresh" as it cost me hundreds of dollars to get a reliable record compared to the price of 4 batteries. I can't change batteries in the middle of a gig and even lose 10 seconds of audio. Now, with this cable, I can power Zoom with a portable $5 USB rechargeable battery that can also power my iPhone. Why didn't Zoom think of that? Well, for less than $10, you'll never need AA batteries for your zoom ever again.
