Rock Solid Auto Pump

Single-Speed Operation

For users who find a hand bulb tiring, this battery-powered penis pump builds suction at the press of a button instead. Your hands stay free while you watch the transparent tube.

It runs at a single speed, so there are no modes to cycle through. You power it on, let the motor draw the air out, and watch through the transparent tube. It runs on two AAA batteries, which are not included.

Design & Build

The vacuum cylinder is fully clear and printed with centimeter markings along its length. That makes it easy to see your position in the tube and compare one session with the next. A pressure meter gauge sits on the unit so you can read the suction level instead of guessing.

At the open end, a soft silicone sleeve rests against the body to form an airtight seal. That seal is what lets the motor hold suction. When you are done, the air release button lets the pressure out quickly so you can slide free without fuss. The materials are phthalate-free and body-safe.

Dimensions

The pump measures 10.75 in. (27.3 cm) in total length, with an insertable length of 7 in. (17.8 cm). The unstretched inner diameter is 3.07 in. (78 mm), and the circumference is 7.75 in. (19.7 cm). Check these numbers against your own measurements before buying so the cylinder fits comfortably.

Power and Use

This is a straightforward tool. One speed, a readable gauge and a quick-release valve keep the learning curve short. Keep two fresh AAA batteries on hand since none come in the box.
