Power Transformer for Pump In Style Advanced - part number 9207041.
Note - this transformer only works with Pump In Style Advanced breastpumps manufactured prior to 2008, and it is not compatible with any other Medela breastpump or any Pump In Style Advanced breastpump manufactured in 2008 or later. If you have a Pump In Style Advanced and it says "12V" on the faceplate, then this is the correct transformer. If you have a Pump In Style Advanced that says "9V" on the faceplate, you need to order the original version of the transformer at this link.
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.
