I charge my trusty Zoom Q4 camera with this usb charger regularly. It never lets me down. I shoot most of my acoustic folk youtube movies with it, in my comfortable home studio. I am a professional singer / songwriter if you Google me: Robin Rowley, on "The Voice Senior Belgium" and also youtube. I have been experimenting with various types of lighting, especially a backlight, which gives good depth to the pictures. Yes, if necessary, I would replace this essential piece of kit in a heartbeat.
