Lelo F1S V2 Rechargeable Sonic Male Masturbator SDK

The Lelo F1S V2 in striking red and black is an interactive male masturbator built for those who like to take charge of their pleasure. Its improved design combines a flexible inner sleeve, a broad range of sonic intensities and four distinct pulsation patterns, all powered by Lelo's open-interface SexTech. Ten precision sensors monitor performance in real time and share it with the Lelo app, letting you build and refine the patterns that work best for you. Modern, rechargeable and fully app-capable, this male masturbator turns a solo session into something you can truly personalise.

Key Features

• Wide sonic range: An expanded range of sonic intensities carries sensation through the sleeve for a deeper, more enveloping feel.
• Four pulsation patterns: Switch between four pulsation patterns to keep every session fresh and varied.
• Flexible sleeve: The improved flexible inner sleeve is designed to respond closely to you.
• Real-time sensor feedback: Ten sensors track the device's performance live and report to the Lelo application.
• App and SDK ready: Pair over Bluetooth with the F1S app, and use the iOS or Android SDK to create bespoke, connected experiences.
• Rechargeable power: A Li-Ion 850 mAh 3.7 V battery charges in roughly two hours for about two hours of use.
• Intuitive locking controls: A centre button and plus and minus buttons manage power and intensity, with a lock feature to avoid accidental activation.

Why Choose the F1S V2?

What sets the F1S V2 apart is the level of control it offers. Rather than a single fixed sensation, it lets you adjust sonic intensity and pulsation on the fly, then use the app's live feedback to shape the session around your own responses. For the adventurous and technically curious, the open SDK means the device can be extended well beyond its standard settings.

This red and black version is ideal for users who enjoy experimenting and want a masturbator that grows with them. The flexible sleeve and adjustable intensities cover gentle, teasing play through to something far more intense, while the rechargeable battery and lock function keep daily use simple and discreet.

How to Use and Care

Give the F1S V2 a full charge of about two hours before you first use it. Without the app, press the centre button to switch it on and adjust the intensity with the plus and minus buttons; holding both together locks and unlocks the device so it will not turn on by accident. To connect the app, hold the centre button to power on while enabling Bluetooth, then confirm pairing in the F1S application when the message appears. Use plenty of water-based lubricant for comfort. Clean the sleeve after each session in line with the manufacturer's instructions, dry it fully and store it somewhere cool and dry, out of direct sunlight.
