Medela Pump in Style Battery Pack | Portable Power for Advanced Pumps

The Medela Pump in Style Battery Pack is a purpose-built power solution for the Pump in Style Advanced breast pump. Designed as an authentic Medela spare part, it’s engineered to work with Medela’s 9-volt Pump in Style Advanced models produced from January 2008 onward. With this battery pack, you gain pumping freedom—no outlet required, no need to plug in first, and no interruptions if you’re away from a wall socket.

Real-life use cases include pumping in the car during a family trip, pumping in a quiet hotel room, or simply keeping your routine when you’re traveling light. The unit accepts 8 AA alkaline or rechargeable batteries and delivers up to about two hours of pumping time, depending on battery type and pump settings. For best results, many users opt for rechargeable batteries to keep you going through busy days.

What’s included: a battery pack and a padded microfiber case to protect the unit during travel. The compact case can slide inside your breast pump bag or attach to a strap for hands-free transport. Note that the battery container identifies 12V as the total voltage of 8 AA batteries; the reference to 9V is about compatibility with the pump’s transformer.

Compatibility and authenticity

Because this is an authentic Medela spare part, it’s designed, tested, and approved to work with Medela equipment. It’s compatible with Medela Pump In Style with MaxFlow and Pump in Style Advanced pumps manufactured from January 2008.
