I have a used Medela pump in style advanced in great working order in the backpack for easy packing around. It is a double breast pump to make pumping go much faster. It comes with power supply to either plug in as well as a battery pack that can provide up to 2 hours of pumping on the go. I have also included the extra cooler in carry kit with ice pack. It includes all accessories including many bottles, tubes, some nipple shields. Some things are still in packaging, those used have all been sterilized. Let me know if you are interested and have any questions. $75 OBO. This ad is cross-posted.
