Pocket-Sized Portable Breast Pump for Parents on the Go

The size of a sticky note yet delivering hospital strength suction, the Cimilre E1 Double Electric Portable Breast Pump is ultracompact, super quiet, and rechargeable, designed for parents who need a high-performance pump with the portability to fit into your pocket or handbag. Now the E1 includes a lanyard! While earlier versions did not include a lanyard, we are excited for this new addition as we're always making improvements for moms.

Why People Love the Cimilre E1 Portable Breast Pump:

• Compact & Ultra Portable: At just 0.37 lbs and the size of a sticky note, the E1 slips into any bag or pocket, ready for travel, work, or spontaneous on-the-go pump sessions anywhere. 
• Rechargeable & Discreet: Built-in lithium-ion battery and LED display with timer, whisper-quiet motor, plus an auto shutoff after 30 minutes, makes late-night or discreet pumping simpler. 
• Simple-to-use: No complicated modes or settings. Choose from Massage or Expression Modes with easily adjustable suction levels for gentle letdown and efficient milk flow. 
• Comfortable convenience: Soft, lightweight lanyard lets you move, hold the baby, or handle quick tasks without needing to hold the pump.

• Stylish & Personalized: Customize your E1 with optional breast pump decal for a fun, personal touch, no more boring pumps! 

Get the Right Fit – Choose Your Breast Shield Size

The right breast shield fit is essential for comfort and effective milk expression. Every E1 includes two standard shield sizes, but if those don’t fit, Cimilre’s Get the Right Fit program lets you choose a free breast shield size. With this personalized sizing option, you can ensure every pumping session feels right for your body.
