I need to travel to Asia for a week. I have had supply issues and have been using the Medela Symphony. I checked the voltage label which indicates it should be fine for up to 240V (implying it can be used with an adapter abroad). However when I called Medela Customer Service they said they do not recommend traveling outside the US with the Symphony. They recommend traveling with the Pump In Style. I was originally using the PIS and since I had supply issues, the LC recommended I switch to the Symphony which has been great. I used to get less milk when I use the PIS, and I am afraid that a week of using it will cause my supply to tank. Are there any other hospital grade pumps that I can travel internationally with? Any other ideas?
