  • This came with my pump and is wonderful to have when out and about running errands or as back up when no outlet is available. Same strength and has lasted several weeks before needing to change batter Apr 21, 2019

  • I loved having a battery back that was compatible with my Spectra S2 but I found a HUGE difference between the first and second pump. I needed to change the batteries every time for the best suction. Apr 11, 2019

  • This eats batteries like crazy. We bought a car converter and I just use that when j need to pump and am out. Apr 08, 2019

  • A must for traveling, but 6 batteries is a lot! Especially when they all die & you have none to replace! Apr 02, 2019

  • It's great in a pinch but the runs out of power so quick! I wish it was rechargeable Mar 23, 2019

  • Worked well for me. Didn't have any issues. Feb 21, 2019

  • It’s a nice option when I need to pump without plugging in. Downside- requires 8 batteries and it’s heavy. Jan 19, 2019

  • It's great to have when you need it, but don't rely on it. It EATS batteries, takes 4 AAs, and I dont think it really provides enough power as it seems lower suction when using the pack 5/10 Jan 16, 2019

  • Works okay... suctions decreases significantly when running off brand new batteries. Burns through batteries FAST! Great for when you need to pump on the go occasionally. Jan 07, 2019

  • A complete and total life saver. I am not a fan of the hand that pump. So when I wasn’t able to use my regular connector I used this one. Dec 31, 2018

    Great for on the go, always good to have a second battery pack Dec 08, 2018

  • Very handy to have the battery back when you don't have access to a plug and need to pump! Sep 19, 2018

  • This helped me to be able to pump anywhere. My only complaint is that I have to change the batteries often. Sep 17, 2018

  • This is a game changer when you need to pump but cant find an outlet. Its super easy to use. Only downside is it requires 8 batteries to function. Aug 01, 2018

  • It wasn't as powerful as the original power plug but that is to be expected. It may breastpumping in car really easy. I used it while my husband drove during long car rides. Jul 10, 2018

  • It takes 8 batteries to use it and it goes through them quickly without giving much power. I prefer my car adapter when I can. Jul 06, 2018

  • I was always home with my daughter, so when I actually needed to pump, I was usually somewhere without a plug. Basically, my pump without this accessory would have been entirely useless. May 31, 2018

  • Pumping on the go, works with spectra May 27, 2018

  • I like this better than the car adapter. May 22, 2018

  • Suction with battery power isn’t as strong as when plugged into outlet, but it does the job if there’s no outlet around! May 11, 2018

    Allows to you to pump anywhere! May 04, 2018

  • Great to have to be able to pump in the car and on the go Mar 21, 2018

  • Was handy, but it requires 8 batteries and i felt like i was replacing all 8 every 3rd pump i used it. For sure only use when there is no other options! Mar 09, 2018

  • This takes 8 batteries, yes EIGHT! And doesn’t last that many pumps. Only get it if you need it otherwise the vehicle outlet or the plug in is the way to go! Mar 06, 2018

  • Essential for pumping away a power source. Feb 25, 2018

  • This is a must have for when the power is out and you have to pump. It’s also nice to not be stuck to the wall while pumping. I haven’t had to change batteries in 6 months Jan 31, 2018

  • I was so excited for this, but it didn’t work well for me. I have to use the pump up all the way and with this I couldn’t get the power needed. It did help provide relief when I was engorged. Jan 14, 2018

  • Great for pumping on planes and other spots where there is no access to a plug. A literal life saver! Jan 08, 2018

  • This is a lifesaver for pumping in the car on the way to work! Jan 06, 2018

    This is nice to use if you need to use in the bathroom. The problem is it's not that powerful. Nov 10, 2017
