Our regular BarreLEDecor Tables have to be plugged in for our LED lights to be on to highlight the beautiful char inside our barrels. However with our new barrel we now offer a rechargeable battery pack that allows our tables to be put in the center of any room. Depending on the battery the lights can remain on from 8 - 40 hours. This allows our barrels to be displayed in the center of any room without a cord. Great for wine cellars, bars, or restaurants.
