What it does

Hercules II creates a sealed vacuum chamber around your penis, generating suction that encourages blood flow into erectile tissue. As pressure builds, you feel a gradual pulling sensation that intensifies as the chamber fills. Your cock becomes increasingly sensitive as blood pools in the penile chambers, stretching them beyond their normal capacity and creating visible temporary enlargement during and after each session.

Automatic pressure control keeps your chosen intensity steady while you focus on the sensations building around you. Start gently at lower KPA levels and work up as your comfort grows. If you want a different feel, Realistic Penis Sleeves offer a stroking sensation rather than vacuum suction, giving you another way to train and enjoy your penis.

Safe, gradual use

Start conservatively with lower KPA levels in your first sessions and let your body adjust to the sensation. Keep each pumping session to 10–15 minutes maximum and use the quick-release valve if pressure ever feels uncomfortable. Avoid this device if you have blood clotting disorders, take blood-thinning medications, or have existing penile injuries. Men with diabetes should consult a healthcare provider before beginning pump therapy. Cockringshop specialises in products for men and couples, and we recommend speaking to a doctor if you have any health concerns before use.

How to use it

Apply water-based lubricant generously to your penis and the inside of the TPR sleeve. Insert your penis fully into the chamber and choose your preferred ring size to seal around the base. Power on the device and gradually increase the pressure using the digital controls, watching the LCD display as you go. Focus on the sensations as suction builds and maintain your chosen intensity hands-free.

Keep each session to 10–15 minutes maximum, using the quick-release valve for instant relief if needed. After use, remove the sleeve and clean it thoroughly with warm water and antibacterial soap. Wipe the electronic components with a damp cloth only—do not submerge them.

Who it suits

Hercules II works well for men seeking measurable enlargement through controlled vacuum therapy. Beginners benefit from the digital pressure monitoring, which guides you toward safe intensity levels. Experienced users appreciate the 350KPA maximum, which delivers stronger suction for advanced sessions. Multiple ring sizes let you customise your experience based on your anatomy and how much experience you have with pumping.

Skip this device if you have blood clotting disorders, take blood-thinning medications, or have penile injuries. Men with diabetes should check with a healthcare provider first. If you prefer a gentler or different sensation, other options in our Pumps, Extenders and Sleeves range may suit you better.

Tested and quality-checked

Every new line we stock is hands-on tested before it ever goes live — we power it up, run it through its functions, and check it for safety and for how it actually performs. Overseas orders get a second function-test right before they ship, so a dead motor never reaches your door. Nothing is used for its intended purpose; it is checked, inspected, and re-boxed. What that means for you is simple: the unit you open is one we already know works. See how we test every product →

How it compares

Penis pumps like Hercules II work by creating suction that draws blood into the penis, whereas Penis Sleeves wrap around your shaft and rely on stroking motion and manual or partner play. Pumps build pressure gradually and hold it, while sleeves give you direct sensation through friction. Choose a pump if you want sustained suction and measurable pressure control; choose a sleeve if you prefer hands-on stroking or partner involvement during use.

Please read — safety first. Put the ring on before you are fully erect and use plenty of water-based lubricant so it slides on without pinching. Keep wear time short — no more than 20 minutes while you are getting used to it, and never fall asleep wearing one. Take it off straight away if you feel numbness, coldness, a change in colour, or any pain, as these mean blood flow has been cut off too far. Never share between partners without cleaning the item first or using a fresh condom. As porous materials can harbour bacteria, use a condom over them for sharing or easy clean-up. This information is general in nature only and is not medical or professional advice, and does not take your personal circumstances into account. Stop use and speak with a qualified medical professional if you have a relevant health condition, take medication for erectile function or blood pressure, or notice pain, numbness, or discolouration that does not settle.

What you can use it with

Pair Hercules II with Couples Intimacy Kits to involve your partner in your enlargement sessions or to extend the experience into partnered play. A cock ring worn after pumping can help maintain firmness and blood flow, while kits designed for couples let both of you participate in the session for shared pleasure and connection.
