Thats probably not enough to charge larger devices like an iPad. These run terribly small! The circuitry and specs for this microphone are the same as a vintage model U-87 Neumann. This is quiet enough that I can get away with using it while on the phone. Compression is gradually reduced with each washing. I intend on ordering another for hats in my closet. I have to take them off and put regular headphones in to hear in stereo when I get a call. The ends of the cords seem to break too( Why I have the tape on it). I really doubt many people will have heard of it. Holds two full size towels, and doesn?t tip over.
