A:AnswerYes, it is completely safe to leave the Link 20 connected to the power whether it is in use or not. Take note that using the Link 20 while plugged in will prolong the charging time.
A:AnswerYes using Google Home app on your phone, you can group the speakers into a stereo pair, with one being the Left channel and one being the Right channel. Works well and the audio experience is more than the sum of it's parts... the combined audio sounds much better.
Note, can only be done over WiFi using Googl Home and/or casting to the device as a Chromecast destination... when using bluetooth, it doesn't appear they can be 'stereo paired'.
A:AnswerThey can not play at the same time from the same source. Flip4 uses BT and can share the BT signal with other JBL Connect+ speakers whereas Link20 is a Google enabled speaker that primarily uses Wifi with a secondary connection of BT. They are both great speakers just different uses
A:AnswerYes, Google music is the default source of music if you ask the assistant to play some tunes. Also Chromecast is the streaming technology supported.
A:AnswerNo, the JBL Link 20 makes use of the Google Home app to connect to other Google Home speakers while the Boombox makes use of the JBL Connect+ (not compatible with JBL Connect speakers).
A:AnswerPairing is for Bluetooth, Linking is for Google Home.
As long as your tablet is on the Same WiFi network name (linksys vs linksys-5G) and you're using the same Google account, it should be listed in Devices in the Home App.
If any of those items aren't the same (like using another google account), you'll have to link your account or join the same WiFi Name.
A:AnswerNot sure. I don't see anything regarding 220 AC in the paperwork or online. Your best bet would be to contact JBL support. It does sound very good and works as described with the Google Assistant.
