Medela Mains Power Adapter for Swing breast pump.
In New Zealand we have 240 volts 50Hz power supply. If your power pack is labelled as "110volts 60Hz" then it will not work in New Zealand, and you will need to purchase a NZ adapter. These are rated for New Zealand & Australia power sockets.
The model on this page is suitable for the Medela Swing Breast Pump (single)
We do have adapters available also for the double pumps of Pump in Style - Freestyle - Swing Maxi breast pumps, but you need to order via this other page.
