In the product details it states this keyboard can be connected to tablet via USB. This is true if your tablet has a USB port, and there's only one that I know of that does have this. Most tablets have a cable that has a male end that allows you to plug into a computer which would be the female end. So it would be more convenient to have a female end with the keyboard to connect with the charger. I had to purchase an adapter just to hook up my tablet to the keyboard. This not being a common item, it cannot be found in stores. If the picture or description would have been more in detail I would have chosen another product instead of waiting on another item to come in the mail. I have not even been able to use this keyboard in the month I have had it. Everything else about it is fine just would've wished to know up front that I would be spending more money just to make this work.
