I bought a klipsch KMC 1 bluetooth speaker a few months ago on Groupon. It came with an AC adaptor it can run off of. I was wondering if anyone knows if I can keep it plugged into the AC adaptor all the time except when I take it on the go or outside? I was just wondering so that way its charged all the time when I need it and ready at the last second instead giving it the full 12 hours it needs to charge from empty.
