5V1A Dual Power Port

Recycle an old USB 5Volt 1Amp charger to power some fans, motors, lights etc (total current drawn by devices should not exceed your charger's ampere output).

This little box links one USB cable to 2 x 2.1mm DC socket female jacks (panel mount type). Connect your fans to male sockets and you have a neat cabling solution for any purpose you can think of.

My recycled USB charger sits on a multi-socket with my printer and both power on/off together. One fan cools the chassis undercarriage, the other cools the extruder.
