Hey, thanks for your attention.
1. Yes, besides the USB-C port, there are two other switches on the side, one for Bluetooth connection, another one is the battery on/off. (1000mAh lithium battery inside)
2. No, they are not programmable RGB. Is it necessary for you?
3. This one was designed without LED backlit, after serious discussion, we decided to sacrifice the led backlit which make the keyboard battery can last more than 30 or 40 days.
Btw, here invite you to join our survey for the GG60-Pro, appreciate your feedback.
