Elvie vs Momcozy pumps compared – differences and similarities

What makes wearable electric breast pumps such an attractive option for pumping moms? Their portability! Instead of being tethered to the wall every time you want to express milk, you can wear both the Elvie and Momcozy wearable breast pumps in standard nursing bras

You can express breast milk while you’re shopping, attending meetings, playing with your baby, or resting. Both the Elvie and Momcozy pumps are small enough to fit into a bag or pocket to take with you wherever you go when not using it for pumping. 


Because you can put the breast pumps into your nursing bra and switch it on to start pumping, there’s no need to use your hands once the milk starts flowing. The all-in-one design means all the necessary parts are in the bra and small enough to be held in place by this underwear item. 

Rechargeable Battery

Both Elvie and Momcozy breast pumps come with built-in rechargeable batteries. The Elvie wearable breast pump takes up to two hours to fully charge with a micro-USB cable, giving you up to 2.5 hours of pumping time, depending on the settings you use.

The Momcozy wearable breast pump takes up to 2.5 hours to charge fully with a USB charging cable. It gives you 70 to 90 minutes of pumping time, again depending on which settings you use. 


Each Elvie pump has seven intensity settings, giving you a total of 14 variable suction levels when using the double set. The Momcozy breast pump has the option of 5 different suction levels (10 on a double set), with the suction value range being between 120 and 300mmHg

Noise Levels

Both Elvie and Momcozy pumps are ultra-quiet, meaning you don’t have to worry about others hearing you pumping on the go! Elvie’s patented technology minimizes the noise level, switching it to stealth mode as soon as you start expressing milk. 

The Momcozy pump noise level never goes over 55dB meaning it’s really hard for anyone to hear the pumping in action!


The Momcozy breast pump comes with two milk collectors made with food-grade silicone. Each bottle can hold up to 6 ounces of milk. The Elvie pump comes with four bottles constructed with BPA-free materials. Each bottle can collect up to 5 ounces of milk and they can be kept in the fridge or freezer

Both Elvie and Momcozy bottles are dishwasher-safe in the top rack. 

Manual or Smart Technology

While you can manually set the settings on the Elvie breast pump, you can go one step further and install the app onto your mobile. This allows you to operate the pump remotely, while also accessing insights such as pumping history and milk volume per breast. 

The Momcozy pump doesn’t use smart technology so there’s no app to use. You have to manually press buttons on the pump for settings such as massage mode, suction mode, and intensity level. 

Breast Shields

Breast shields play an important role in keeping your nipples and surroundings comfortable during pumping. The Elvie double breast pump set comes with two 24mm and two 28mm breast shields

Watch this video showing how to fit the Elvie breast shields.

The Momcozy double set comes with two 24mm breast shields. Additional breast shields in different sizes can be purchased separately from Momcozy. 

Elvie pump review

Elvie Breast Pump - Double, Wearable Breast Pump with App - The Smallest, Quietest Electric Breast Pump - Portable Breast Pumps Hands Free & Discreet - Automated with Four Personalized Settings

Out of all the Elvie pumps available, the Elvie Double Electric Wearable Smart Breast Pump is one of the most popular choices among breastfeeding moms looking for a portable design. 


The stand-out feature of this wearable electric breast pump is that there are no wires or tubings to fiddle with. Being able to operate it remotely with its in-house app also makes it one of the most convenient hands-free breast pumps to use while expressing milk. Two modes, including let-down mode and auto-shutoff at 30 minutes are other features worth noting. 

There’s a two-year warranty on the pump mechanism and 90 days cover on all the washable parts. Assembly is quick and easy with only five parts to worry about. Two carry bags and four bra strap adjusters are also included in the set. 

Why consider it

If you’re a busy breastfeeding mom, always on the go but wanting to make sure your baby gets all the nutrition they need, this wearable breast pump is a good solution. You can express milk confidently, no matter where you are. Additional bottles mean you can store pumped milk in a cooler bag while using the extra bottles in the next pumping session before feeding your baby. 

It’s a great solution for working or traveling moms going away overnight. The bottles can be kept in the fridge or freezer until you return home. Or, you can transfer breast milk storage bags or bottles. Best of all, the breast pumps fit comfortably into a standard nursing bra which can be adjusted with bra adjusters


  • Adjustable suction modes matching breast supply
  • Long battery life while pumping
  • Ultra-quiet


  • Expensive compared to Momcozy wearable breast pump

Momcozy pump review

Momcozy S9 Wearable Breast Pump, Hands Free Breast Pump, Portable Electric Breast Pump with 2 Mode & 5 Levels, Painless Breastfeeding Breastpump Can Be Worn in Bra, 24mm Grey,2 Count (Pack of 1)

The Momcozy S9 Double Wearable Breast Pump is an affordable wearable electric breast pump that has good features suitable for most pumping needs. 


Also completely hands-free and wearable inside a nursing or normal bra (which can be altered for more comfort with a bra adjuster), this breast pump is wire- and tubing-free. It comes with two modes – Stimulation and Expression – and five adjustable suction levels. The milk collectors are spill-proof containers and an auto-shutoff timer gives you peace of mind that your bottles won’t overflow. 

The 6 oz bottles are slightly bigger than the Elvie containers, making it an attractive option for moms with an oversupply of milk. A duckbill valve also prevents any messy backflow. It’s small enough to pack into your bag, pocket, or diaper bag, making it a portable breast pump for the mom on the go.

Why consider it

If you’re looking for a cost-effective wearable electric breast pump with more bottle capacity and powerful suction level ranges, you won’t be disappointed with this design. Its simple press button features also make it easy to operate. 

Fewer parts and no tubing means less washing and the washable components are dishwasher-safe


  • No need to be tethered to the wall while pumping
  • Easy to clean and maintain
  • Well-priced


  • Pump can detach from the bottles during pumping
  • Battery slows down quickly

Is Elvie better than Momcozy?

My top pick is the Momcozy S9 Double Wearable Breast Pump because of its attractive budget-friendly price. You’re not compromising on quality or efficiency either with its range of features sufficient for getting the job done. It’s quiet, fairly discreet, has ample suction, and is portable. 

I would highly recommend getting a good breast milk cooler when you’re pumping for ultra convenience when using wearable electric breast pumps. This way, you can store expressed milk safely before your baby’s next feed.
