Dear Guangwei Che, If your Nexbook has an extra USB port then you should be able to plug this keyboard in and start typing. this keyboard does not have a Bluetooth feature. Hope this info answers your question
The case fits any tablet that measures 8 x 6, But the keyboard would not work even with an adapter. I think there is a problem with the metal prongs of the USB cable to keyboard. Otherwise its a great case, if I could get keyboard to work.
