A:AnswerWe don't have a specific microphone model that we can recommend with our JBL PartyBox 100. You can use any generic microphone that can be plugged in with the mic input of this speaker.
A:AnswerYou can use a 3.5mm aux cable to connect the speaker to your smart TV. If you need more help, please contact us, so we can assist you: https://support.jbl.com/us/en/#contact
A:AnswerOur JBL PartyBox 100 can connect to other JBL PartyBox 100 and play together, you can also connect them via the cables behind for more speakers. It's worth it since it's rated highly and the sound quality is good.
A:AnswerNot sure on how many charges you get but it does have a normal power cord that can be used “for charging or for normal use” so if the battery dies it’s still useful just stationary to a 110 power outlet.
