    5.0 out of 5 stars Lifesaver & super convenient.
    Reviewed in the United States on May 2, 2016
    Verified Purchase
    I recently bought this for the upcoming camping and sports season where an outlet and a car won't be close by. I have used it a few times and am very satisfied with the product. It does take a lot of batteries and drains faster than I like but I still get a good number of pumps with adequate suction that the battery life does not bother me. The battery life isn't horrible considering but its not going to last days on the same set of batteries. But I'm sure a good rechargeable would be perfect for those long times away if you can find a way to charge them. I don't mind replacing the batteries as I had realistic expectations of battery life when I purchased this product. I look at battery life on this like I do my phone the more you use it the faster the battery drains. I am sure if you streamed videos or music while pumping the life of your phone would probably die at same time if not sooner than pump.(I'm going to try this and let you know) I am super happy with this purchase if you have ever been out and about and its time to pump but you have no outlet near this is a saving grace. The price of the device is amazing the little case is awesome and I can see this getting a lot of use over the summer and would recommend to anyone super convenient and perfect for the mom on the go.

    Reviewed in the United States on August 17, 2018

    Works exactly as described. I use this on planes, in the car or anyplace else I don't have an outlet. On a plane I 100% recommend using this over an outlet on the plane (such as in the lavatory) because it is not the same current and your pump will not operate well at all. I never bought the car adapter so I can't compare that, but I liked that I didn't have to have the car on to use this. So I could discreetly sit in the car and pump while parked.

    There will be a degradation in pump performance as the batteries get used, and there isn't really a hard and fast rule despite what Medela says about # hours you can use. I say just change the batteries when you notice it starting to get weaker! If the batteries are good, you should not notice a difference between this and being plugged in.

    I also used this in Europe because you cannot just plug a US Medela power cord into an adapter because the voltage is not the same and the motor will not work on European voltage. Don't risk it, just use the battery pack!

    After using this product, I found that it works great when I have to pump in a public place like the restroom. Of course the restroom has no outlets and it starts a lot of bathroom conversations, but again great! I bought rechargeable batteries (highly recommend investing in energizer batteries and the charger that does AA, AAA, C (can charge that bouncer!!), D, and 9V)and I charge it every night before I go to bed like my cell phone. It is slightly weaker than what an outlet or the car charger does, but it works! It does take a little bit longer too. Note: Do not leave the batteries in the battery pack! When the batteries make a complete circuit, it starts to drain the batteries. I saw a few reviews that said they didn't get that much pump action with the batteries before it died so taking out the batteries when not in use will save you some trouble.

    This product is AMAZING! I went to Paris for four days and pumped every four hours and the batteries lasted the entire time! I couldn’t believe it! Great for traveling. I used this with my medela pump and freemie cups. I ordered the freemie pump and it was the worst with no suction so this was my backup plan and it worked amazingly! Carried in a backpack throughout Paris and this paired with freemie cups enabled me to keep my pump in a bag next to me and pump on the plane/meals/etc without anyone knowing! It is also great for travel abroad because you don’t have to worry about frying your pump with converters/adaptors. Couldn’t recommend enough!
