I am not home most of the time since I got college so I was wondering if it’s ok for me to just leave the JBL extreme plugged into the adapter to charge since I have a tendency to forget to unplug it whenever I go out.

Not fully recommended, because the lithium ion battery will get worn down and in some rare occasions eventually get hot enough to flame up (if left plugged in for a long long time and the wrong charger gets used)
