Hi Maura! Thanks for asking this question. What you should see, when you plug a speaker in to be charged, is a steady red light. The light goes off at the end of charging. However, while I can say the sound and operation of the speakers has been solid, there have been a two units with a questionable red light–that’s out of several hundred, but still.

This does not mean it isn’t charging. For a good charge, just leave the units plugged in overnight, and they should play again for a long, long time–this can mean months! As long as they are playing, all is good.

Good to have you along with us. Stay in touch. 🙂
