The Huge Gains automatic penis pump comes already assembled and includes a silicone cylinder sleeve. For cleaning purposes, the plastic cylinder detaches easily by pulling it away from the motorized handle.


Huge Gains uses three (3) AAA batteries (not included). Remove battery compartment cap at the top of the motorized handle, by twisting counter-clockwise until the arrows are aligned. Insert batteries as directed by the removable battery holder. Replace battery compartment cap by twisting it clockwise, until the top arrow aligns with the lock symbol.


Always use a body-safe, water-based personal lubricant to ensure the longevity of your toy. Apply liberally to toy and any intimate areas toy may contact.

  1. To use, place the silicone sleeve over the insertion end of the cylinder. Apply water-based lubricant to the silicone sleeve and then to your member before inserting yourself through the opening.
  2. To power on your Huge Gains penis pump, simply press the top power button. This will begin suction on level 1. Use this button to increase the suction intensity as many as 2 more times.
  1. On the 4th press of the power button, the suction functions will turn off.
  2. To release suction, turn off the suction as described above. Then hold the bottom quick-release button to instantly decrease pressure.
  3. After use, remove device and secure a constriction ring around the base of your penis if desired.
  4. Remember to remove batteries from battery compartment to prevent any potential battery damage or leakage.


If pressure is too intense, decrease intensity or remove device right away to prevent any bruising or strain. Do not use for longer than 20-30 minutes at time. Do not wear the constriction ring for longer than 30 minutes at a time.


After use, clean and sanitize your toy thoroughly. For thorough results, we recommend you clean your toy thoroughly with a reputable foaming or misting toy cleaner.
