The board with two chips on it is the transmitter (power with 9V). The longer board is the output and you can connect that to the part of your project that needs powering. Inductive charging is a way of powering a device without a direct wire connection. These chargers work by taking a power transformer and splitting it in half, an AC waveform is generated into one, and couples into the second coil. This is a basic charger set, and it does work, providing 5V DC output from the output half when the input half is powered with 9V to 12VDC. You can draw, as much as 500mA if the coils are 2mm or 3mm apart. If you only need 100mA or 200mA, you can be up 7mm apart. For 10mA draw, the coils can be up to half an inch (12.5mm) apart. Any non-ferrous/non-conductive material (eg air, wood, leather, plastic, paper, glass) can be use between the two coils.
