Quick answer

Setting up your Lansinoh Rechargeable Double Electric Breast Pump Kit is straightforward: wash all parts, charge the pump fully before first use, then assemble the bottles and flanges according to the included diagram.

Before you start: what you need to know

The Lansinoh Rechargeable Double Electric Breast Pump Kit comes with a rechargeable battery that offers up to 3 hours of cordless pumping between charges. Make sure you charge it fully before your first session to avoid interruptions.

All parts that contact milk (bottles, flanges, valves, membranes) must be washed and sterilized before first use. Follow the manufacturer’s cleaning instructions to keep the pump hygienic and working efficiently.

Step-by-step setup instructions

  1. Step 1: Charge the pump: Plug the pump into a USB power source using the included cable. Charge until the indicator light shows full (about 2-3 hours). Do not use the pump while it is charging. A common mistake is using the pump before the first full charge, which can cause it to run out of power mid-session.
  2. Step 2: Wash and sterilize all parts: Disassemble the bottles, flanges, valves, and membranes. Wash them in warm soapy water, rinse thoroughly, then sterilize using a steam sterilizer or boiling water for 5 minutes. Let them air dry on a clean towel. Make sure the small white membranes are not stretched or torn after washing—they create the suction seal.
  3. Step 3: Assemble the pump kit: Attach the flange to the bottle, then insert the valve and membrane into the flange opening. Connect the tubing to the flange and to the pump unit. Ensure all connections are snug but not forced. If the tubing is kinked or not fully pushed onto the connector, the pump will lose suction.
  4. Step 4: Select your flange size: The kit includes a standard flange. If you have a different nipple size, use the Lansinoh flange sizing guide to choose the correct fit. A proper fit means the nipple moves freely in the tunnel without rubbing the sides. Using the wrong flange size can cause pain, low milk output, or blocked ducts. Measure before your first session.
  5. Step 5: Start pumping: Press the power button to turn on the pump. Use the letdown mode (faster, lighter suction) for the first 2 minutes, then switch to expression mode (slower, deeper suction). Adjust the suction level to a comfortable setting. Start on the lowest suction level and increase gradually. Too much suction too soon can damage nipple tissue.
