The Voltaic Systems 6 Watt kit comes with their 6 Watt Panel and their V15 Rechargeable Battery, plus a variety of cables and connectors. The panel charges the battery, which functions like a typical external battery pack common these days with smartphones and mobile devices. The output of the battery is through a standard USB plug.
The EL Wire logo is powered by an inverter that runs off of (2) AA batteries. Since the inverter is necessary for the operation of the logo, it needs to be kept. But the batteries could be replaced by the power from the V15 Rechargeable Battery.
