A really tiny portable inverter for EL wire. Powers off of a single CR2032 coin battery (not included!), it can drive up to 50cm / 20 inches of our high-brightness EL wire or 10cm x 1cm long piece of EL tape for 3 hours (or longer if the EL wire is less than 50cm long). There is a button for selecting steady/blink/off modes. Comes with a 2.5mm pitch female JST connector. Like all inverters we've used, the 2000 Hz oscillation is slightly audible.
This inverter can only power 10 CENTIMETERS (2.5 INCHES) of 1cm wide tape or a 3cm x 3cm / 1.25" x 1.25" piece of EL panel
To connect a piece EL wire to this, you'll want a male connector wire
Soldering to EL wire is a little tricky but luckily we wrote a detailed step-by-step tutorial!
