Australian 3-pin plug. Input: 100-240 V 50/60Hz 0.3A. Output: 13.5 Vdc 500mA. 6' cord with 2.1mm coax plug, center positive. CE. This power adapter should fit most Australian style power outlets, but it is not guaranteed. You may look at the picture and see if it is similar before ordering. If ordered with a feeder, it will be at extra cost. The included standard power supply cannot be removed from it's pre-packed box. NOTE: You will still need a 220V timer (not sold by us) like a lamp timer to plug this power adapter into to operate your Super Feeder.
