# LCD Vacuum Penis Pump – 5 Suction & 4 Pressure Modes

## Product Overview

This powered vacuum pump combines an LCD pressure/battery display, five suction modes, four supplier-labeled pressure/training modes and a one-click pressure-release control. It includes two seal-ring openings and a separate soft contact insert.

## Documented Controls

-   LCD battery and pressure-value display
-   Five suction modes selected with the M button
-   Four pressure/training modes selected with the function button
-   Short press on the power control for one-click pressure release

The current media does not show a separate hand-operated/manual pressure mechanism. The mode labels are supplier descriptions and do not establish a numeric automatic maximum-pressure cutoff or medical-device certification.

## Image-Listed Dimensions

-   Overall product: approximately 11.47 in long and 2.75 in wide
-   Seal-ring openings: approximately 0.78 in and 1.18 in
-   Soft contact insert height shown: approximately 2.95 in
-   Upper control and lower chamber sections are each shown at approximately 2.95 and 2.36 in in the supplier diagram

The current evidence does not provide verified internal usable chamber length, internal diameter or a manufacturer sizing chart. Seal opening and overall dimensions are not a guarantee of fit.

## Pressure and Fit Safety

1.  Inspect the clear chamber, selected seal and release control before every use.
2.  Apply water-based lubricant around the seal and begin at the lowest comfortable setting.
3.  Watch the pressure display and use one-click release immediately for pain, numbness, coldness, swelling, bruising or marked color change.
4.  Fully release pressure before removing the chamber.
5.  Do not sleep with the device or any constriction accessory in place.

This recreational product is not a treatment for sexual-health conditions or lasting anatomical change. Ask a qualified clinician before use if you take blood-thinning medicine or have bleeding/clotting disorders, reduced genital sensation, circulatory problems, diabetes-related nerve damage or a penile injury/condition.
