This inverter is the most common way to power EL wire because they tend to be cheap and batteries generally last a long time. 2 AA Batteries can power an 2.5m strand of EL Wire for about 8-10 hours.We recomend you use the rechargeable batteries, though the operating time might be less. It comes with a constant on/off switch and blink mode. Takes 2xAA Battery (not included). The battery pack comes with a belt clip you can use that to attach to clothing, hats, etc... Battery pack comes with a 2.5mm (0.1") pitch female JST connector. NOTE:We recomend to remove the batteries from the inverter when not in use, because on occasion it is hard to tell if a battery pack is still “On”.
