A:AnswerNo, it's a Bluetooth keyboard that attaches to a Microsoft Surface Pro 4,5,6,or 7. You have to have one of those tablets and together they turn the tablet into something that works like a laptop.
A:AnswerI don't think I have ever charged mine, and it is still going strong after about a month. It was ready right out of the box. I likely need to charge it soon, but it seems to hold a charge well.
A:AnswerBeings that this is a Bluetooth keyboard, technically it will work with a protective case, but you wouldn't be able to attach the surface pro to the keyboard. The case will not fit in the hinges that hold the Surface Pro.
A:AnswerIts only dimensionally-compatible with the Surface Pro 4 and higher. I don't think its a Bluetooth stack limitation as much as the physical dimensions for the SP3 are thicker, so the clasps won't work, but I think the SP3 might have had other functional limits working with this newer version.
