A:AnswerNo, it is entirely connected by the plug. It will remain on until the computer is shut off, so you shouldn't have to recharge it (unless you're using a laptop, in which case the duration of light is reliant on the duration of battery).
A:AnswerYup. The same thing happened to me. You need an adapter that can handle more voltage. I've got a Samsung adapter with "fast charging", so it can handle more power. That one worked fine and didn't get hot.
A:AnswerI think it COULD be used for a video camera, but the camera "stand" that comes with it is designed for a phone. I'm sure you could purchase a separate piece that can adapt to it for your video camera though! Keep in mind, I am NOT an expert. lol.
A:AnswerYES...but....
Yes, it holds a smartphone, but not very well. As a matter of fact- I used it TWICE before the end that pulls back (spring) to allow your phone to fit in- has come apart.
