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.
- Safe for You & Baby: Built with a closed system and BPA, BPS, and Phthalate-free parts to protect both milk and motor.
- 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.

Everything you need to pump, store, and feed is in the box, including two bottles, shields, valves, tubing, and backflow protectors. The included backflow protectors and closed system help keep milk and motor separate for safer use.

Switch between Massage and Expression modes and use adjustable suction levels for gentle letdown and efficient flow. The clear LED display shows level and a timer, and the pump auto shuts off after 30 minutes.

Built-in lithium-ion battery charges via USB-C for easy topping up between sessions, and the motor runs at less than 45 dB for discreet use. The lightweight lanyard and whisper-quiet motor make pumping on the go or at night simpler.
Match pump features to your schedule, comfort needs, and how you plan to use it.
- How often you pump: If you pump several times a day for work, prioritize battery life and consistent suction. For occasional use, compact and travel features may matter more.
- Breast shield fit: Shield size affects comfort and milk removal, so test the included sizes and use the manufacturer sizing program if needed.
- Noise and discretion: Look for a low-decibel motor and discreet design if you need to pump at work or at night.
- Battery and charging: Choose a pump with USB-C charging and a clear battery indicator so you know when to recharge between sessions.
- Extras and warranty: Consider included bottles, backflow protectors, and warranty length when comparing value and long-term support.
