A:AnswerI have no problems connecting multiple devices with this speaker. My family of 5 all can use speaker paired to different phones and iPad If it doesn’t connect right away turn it off and try again. Usually works second attempt at connecting.
A:AnswerMine only took about an hour after using it 9 hours in my truck at work. If you are able to connect to a USB port while using it, it will recharge while in use.
A:AnswerAre you charging it with the stock cable the speaker came with? I’ve found that some micro usb do not charge for example my PS4 micro usb will not charge it so I will use the stock JBL cable with a standard iPhone usb to wall socket
