This is an inverter for EL wire and tape, similar to our pocket inverters, except it is a brick that takes 12V input instead of 2 AA batteries. This means its good for 'fixed' installations since you can just plug it into a 12V wall adapter. It's also good for portable projects where you want to have a big battery pack like an 8xAA holder which will last 4-5 times longer than just 2xAA's. It is also more powerful, and can drive twice as much EL as the 2xAA inverter! Another nice thing about this inverter is it's a potted brick, so its quieter than the 'open' inverters with a switch.
It's got twice the power of the 2xAA pocket inverter, you can drive up to 6 meters combined of our high brightness EL wire (20 feet), or 12 meters (40 feet) of plain EL, or up to 100 square centimeters combined of panel/tape - so either a 10x10cm square or 1 meter of 1 cm wide tape.
