A:AnswerHi kennyg,
You can connect 2 SRS-XB12 using the Speaker Add function. Connecting it to a TV will depend if the TV supports Bluetooth speakers.

A:AnswerThe speaker would only work with a non BT TV with a audio cord to patch it in...this is not the best speaker for you if the TV has no BT. There’s other speakers designed specifically for that situation.
A:AnswerHi, Junya! No, it cannot. Check out the Sony SRS-XB40 instead. The XB40 can charge a USB device, such as a smartphone, by connecting it to the speaker (DC OUT ONLY port) with a USB cable. -Vincent
A:AnswerHi, Me! Charging is completed in about 4 hours and 30 minutes (Time that is required to charge the empty battery to its full capacity when the speaker turns off). ~Ralph
