Quick Answer
To use the Spectra S1 Plus Rechargeable Pump Bundle, start by charging the pump fully, assemble the parts, and attach the bottles.

The Spectra S1 Plus Rechargeable Pump Bundle is a favorite among active moms because it combines the hospital-strength performance of the S1 Plus with a stylish tote and a Pink Cooler Kit for easy milk storage. Whether you're heading back to work or planning a weekend away, this bundle is designed to keep up with your lifestyle.
In this guide, we'll walk you through every step of using your Spectra S1 Plus bundle, from unboxing to storing your milk. You'll learn how to set up the pump, adjust settings for comfort, and make the most of the included accessories. Let's get started.
What’s in the Spectra S1 Plus Bundle?
The Spectra S1 Plus Rechargeable Pump Bundle includes the Spectra S1 Plus breast pump, a tote bag designed to fit all Spectra Baby USA pump models, and the Spectra Pink Cooler Kit. The cooler kit contains a reusable freezer pack and an insulated lining to keep breast milk cold for extended periods. The cooler has a zipper closure and carrying handle, and it fits perfectly inside the tote.
Before you start, make sure you have all the parts: the pump unit, bottles, flanges, tubing, and valves. The S1 Plus is a closed-system pump, which means milk never enters the tubing or the pump itself, making it hygienic and easy to maintain.
Charging Your S1 Plus
The S1 Plus is a rechargeable pump, so you don't need to be near an outlet. Before first use, charge the pump fully. Plug the included AC adapter into the pump and a wall outlet. The battery indicator will show when it's fully charged. A full charge typically lasts for several pumping sessions, but it's a good habit to charge after each use to ensure you're always ready.
A common mistake is forgetting to charge the pump before heading out. Make it a routine to charge overnight or after each session so you never run out of power mid-pump.
Assembling the Pump Parts
Wash your hands and ensure all parts that will touch milk are clean. Attach the backflow protector to the tubing, then connect the tubing to the flange. Place the bottle onto the flange and ensure it's screwed on securely. The S1 Plus comes with two sets of flanges and bottles for double pumping, but you can also pump one side at a time if you prefer.

Check that all connections are tight to avoid loss of suction. A loose connection can reduce pumping efficiency and lead to frustration. If you're unsure about assembly, refer to the instruction manual that comes with your pump.
Pumping with the S1 Plus
When you're ready to pump, place the flanges over your breasts and turn on the pump. The S1 Plus offers two modes: a stimulation phase to encourage let-down and an expression phase for efficient milk removal. Start in stimulation mode until you feel milk flowing, then switch to expression mode.
Adjust the vacuum level to a comfortable setting. It should be strong but not painful. Many moms find that starting at a lower level and gradually increasing works best. The S1 Plus is known for being quiet, so you can pump discreetly even in shared spaces.
Storing Milk in the Pink Cooler Kit
Once you've pumped, transfer the milk to storage bags or bottles. The Pink Cooler Kit includes a reusable freezer pack that you should freeze before heading out. Place the freezer pack in the cooler, add your milk containers, and zip it closed. The insulated lining will keep milk cold for extended periods, making it perfect for commutes or outings.
Remember to label your milk with the date and time. If you're using the cooler for a full day, consider packing extra freezer packs to maintain the temperature. The cooler is designed to fit perfectly inside the Spectra tote, so you can carry everything in one convenient bag.
Cleaning and Maintenance
After each pumping session, disassemble the parts that came into contact with milk and rinse them in cold water. Then wash them in warm, soapy water and rinse thoroughly. You can also use a steam sterilizer or boil the parts according to the manufacturer's instructions. Allow them to air dry completely before reassembling.
The pump unit itself does not need to be washed; simply wipe it with a damp cloth. Regularly check the tubing and backflow protectors for moisture or damage. Keeping your pump clean ensures it works efficiently and lasts longer.
Step-by-Step Pumping Routine
- Charge the pump: Plug in the S1 Plus and ensure it's fully charged before first use. A common mistake is forgetting to charge, which can interrupt a session. Charge after each use to keep it ready.
- Assemble parts: Attach flanges, bottles, and tubing, ensuring all connections are secure. Check that the backflow protector is in place. Tight connections prevent loss of suction.
- Position flanges: Center the flanges over your nipples and hold them in place. A good seal is key for efficient pumping. Adjust if you feel any pulling on the areola.
- Start with stimulation mode: Turn on the pump and let it run in stimulation mode until you feel let-down. This mimics baby's sucking to trigger milk flow. Don't rush; let-down can take a minute or two.
- Switch to expression mode and adjust vacuum: Once milk flows, switch to expression mode and increase vacuum gradually to a comfortable level. It should never hurt. Lower vacuum is better than too high.
- Pump and store milk: Pump until flow slows, then remove and cap bottles. Transfer milk to storage bags or bottles and place in the Pink Cooler Kit with the frozen pack. Label milk with date and time.
- Clean parts: Disassemble and wash all milk-contact parts in warm soapy water, rinse, and air dry. Wipe the pump unit with a damp cloth. Clean thoroughly to maintain hygiene.
