Replacement transformer for Medela Breastpumps. The standard replacement transformer works in the U.S. and in countries using 110 Volts AC. If you will be using the transformer in a country outside of the U.S., please specify whether you need the UK, European, or Australian type. Use the pull-down menu to specify which transformer you need (Pump in Style, Mini Electric, or DoubleEase).
Part numbers for the US version of these transformers:

Part numbers for the European version of these transformers:
Pump In Style: 9207016
Part numbers for the UK version of these transformers:

Please note: The Pump In Style version of this power transformer will not work with the Pump In Style Advanced breastpumps manufactured prior to 2008, but it does work with all versions of the Pump In Style Original, Traveler, Companion and the new Pump In Style Advanced breastpumps manufactured in 2008 or later. (If you have a Pump In Style Advanced breastpump manufactured in 2008 or later, the faceplate will say "9V" instead of "12V".) If you have a Pump In Style Advanced manufactured prior to the year 2008, and it says "12V" on the faceplate, then you would need to order the 12V version of the transformer at this link instead.
Please note, due to slow sales, we have discontinued the MiniElectric and DoubleEase Transformers. We are sold out of the US MiniElectric and DoubleEase transformers but still have the UK and European Versions of the DoubleEase transformers in stock. We have also discontinued the UK and European versions of the Pump In Style transformer, but we still have the US version in stock.
Please see the information on Medela's website at this link for important information regarding a Safety notice on Medela transformers and for instructions on how to properly store and care for your Medela transformer.
