Battery Pack for Spectra S2

The Spectra S1 and S2 breast pumps differ only by the fact that the Spectra S1 has a rechargeable battery pack, and the S2 does not (meaning it always has to be plugged in to a power source to work).  

Because of this, the Spectra S2 tends to be cheaper and what is available via insurance. Also, inexplicably, Spectra refuses to make a battery pack for the S2. Their reasoning is... go buy an S1 if you need to occasionally pump away from a wall plug. 

So what can you do when you're a pumping mom who can't always be next to a wall plug? I've found a solution!

This Medela battery pack... IS COMPATIBLE!

I noticed that my Spectra S2 has a marking for "12V DC" where the power adapter plugs in, and I noticed that the Medela battery pack that I have also has a "12V DC" marking on it, and the plug happens to fit the pump. I plugged it in and gave it a try and it works!

Give it a try and let me know how it works for you!
