I have been Nomail for a week while on holiday, so I apologise that this is a little delayed in response. I have just got back one of the NMAA-owned Medela Lactina pumps I look after, and on the bottom it says "Made in Switzerland Type 016 2018 100-240 V 50-60 Hz 50 VA T 1.25" and some other letters in circles that I don't know what they mean. This looks to me like it would be suitable to run on just about any country's power supply. It is marked as "Lactina Electric Plus". I also have a couple of Lactinas as a (very small) rental station. These are a bit older than than the NMAA one and marked as "Lactina Electric" (no "Plus"). One of these is marked Type 016 2003 220-240 V 50/60 Hz 80 VA T 400 mA. Obviously this one was made specifically for 220/240 V countries only. So just knowing the brands may not be enough - you may need to check individual pumps for their type. Before now I had wondered what the "Plus" meant as otherwise the pumps appeared identical. Joy Anderson IBCLC Perth, Western Australia [log in to unmask]
