Voltaic F3.5x1.1 to Micro USB connector
Connects Voltaic 2.0 Watt, 3.4 Watt or 6 Watt Panel directly to Voltaic V15 battery or device with Micro USB input. Charges many, but not all, devices like smartphones directly from the solar panel (skipping the battery). The 3.4 Watt panel will work in more cases than 2.0 Watt panel.
Please Note, this adapter plug is included with Voltaic 6 Volt Solar Kits that have the V15 battery.
