FAQ
What's the difference between the S1 and the S1 Pro
The main upgrade is the charging case. The S1 Pro comes with a portable wireless case that keeps your pumps powered for up to 5 days between charges — handy if you're pumping at work, travelling, or out and about. The S1 plugs in to charge, so it suits pumping mostly at home. Both share the same heating, app control and 300 mmHg suction, so if you mainly pump at home, the S1 covers the essentials for less. If you need to pump on the go, the S1 Pro's case is worth it.
What's the difference between the S1 and the E20?
Both are heated wearable pumps, but the S1 gives you more control and refinement. It has 7 heat settings (vs 3 on the E20), 7 suction levels, and connects to the eufy app for custom rhythms. The E20 is the simpler, more affordable option — great if you want to try heated pumping with the basics covered. If you'd like more control over warmth and rhythm, the S1 is the better pick.
How do I make sure the pump is positioned correctly?
Getting the right position matters more than anything for a good pump. Before you start, centre your nipple in the flange tunnel — the soft silicone is designed to feel snug, and you can gently adjust until it feels secure and comfortable. Just as important is the right flange size: the S1 comes with sizes from 17–24 mm, and using the wrong size is the most common cause of poor output. If you're not getting much milk, check the fit first — and our support team is always happy to help you get it right.
