Transparent Piston Manual Penis Pump — Max Boost

The integrated piston pump - no bulb, no trigger, no motor, no hose. You insert your penis into the cylinder, push the white head down with intermittent strokes, and the vacuum builds with each pump. The simplest motion in the pump aisle, and the only one that can go directly into the shower as there is no electronics inside.

You pump by pushing the head down

The P3 Action piston replaces everything: squeeze bulb, pull trigger, ribbed tube. You push on the upper white shell, it slides down, and air exits the cylinder via an internal valve. You lift it up, push it down again, and watch your penis swell through the transparent acrylic. A dozen pumps are enough to achieve the desired erection.

Release the pressure by pressing the button

The small metallic ball on the side is the quick-release safety valve. A simple press on it lets air in instantly - useful as soon as it pulls too much, or to remove your penis at the end of the session. This is what makes the Max Boost reassuring for first-timers: you never get stuck in the cylinder.

The Elite silicone seal fits without pinching

The white base is fitted with a hypoallergenic silicone ring that presses against the pubic bone to create a seal without pinching hairs. It detaches for thorough rinsing and can be boiled to sterilize between uses. No plastic odor, no phthalates.

You see your penis progress

The 100% transparent acrylic lets you see your penis swell in real time — the visual dimension lost with smoked cylinders. Insertable depth 19 cm, internal diameter 5 cm — calibrated for most body types. The ruler printed on the wall shows you the progress centimeter by centimeter, session after session.

You can use it in the shower and clean it under water

No electronics = fully waterproof. You can take the Max Boost in the shower, in the bath, or rinse it completely after use without any special precautions. Ideal for starting pumping in the morning before a date, or in the evening with your partner if you want to test the effect together — no cables, no batteries, no noise.
