Our JBL Tuner XL can be used while it is charging. No need to worry since all our products have a PCM (Protection Circuit Module) and charge management IC built-in, that manages and detects the charging of your unit. Once your speaker is fully charged, it will cut off the current to protect the battery. But we still recommend using the speaker on battery mode from time to time though (but not to the point of fully draining it). This is because lithium-ion batteries still slowly discharge themselves over time, which can lead to bad, fully drained batteries. Having a regular charging schedule will prevent this. We would suggest not waiting for the battery to be completely depleted. Once the unit is low in battery, charge the unit immediately.
