Doc Johnson Vac-U-Lock Electronic Suction Cup Mount, 115 mm / 4.5 in, IP65 Heavy-Duty Hands-Free Base for Large Attachments

## Doc Johnson Vac-U-Lock Electronic Suction Base – Smart Auto-Vacuum, 115 mm / 4.5", IP65

Take your hands-free experience to the next level with an intelligent suction mount designed for larger and heavier Vac-U-Lock attachments.

Unlike an ordinary suction cup, this electronic base actively monitors the vacuum pressure while in use. If the pressure begins to drop, the built-in pump automatically restores suction, helping maintain a strong and stable hold throughout your session.

With its extra-wide 115 mm / 4.5-inch base, digital display, rechargeable battery, and water-resistant construction, this is a powerful upgrade for anyone looking for greater stability, convenience, and peace of mind.

### Why This Electronic Base Stands Out

**Active Auto-Suction Technology**
The internal pressure sensor continuously monitors the vacuum level. When pressure loss is detected, the electric pump automatically reactivates and restores suction.

**Heavy-Duty Holding Power**
Designed for demanding hands-free use and larger attachments. The base has been tested to withstand pull forces of up to 75 kg / 165 lbs under suitable conditions.

**Extra-Wide 115 mm Base**
The large 4.5-inch suction surface provides increased stability and better weight distribution compared with standard manual suction cups.

**Digital Status Display**
The integrated OLED screen shows vacuum pressure, battery status, motor operation, and valve status, allowing you to check the system at a glance.

**Water-Resistant Construction**
Rated IP65 for protection against dust and water jets, making it suitable for bathrooms, showers, wet rooms, and other humid environments.

**Rechargeable and Portable**
The built-in rechargeable battery allows cordless operation. Charge the unit using the included USB cable and take it wherever you need a temporary mounting solution.

**Damage-Free Installation**
No drilling, screws, adhesives, or permanent modifications are required. Attach the base to a clean, smooth, non-porous surface and remove it when finished.

**Vac-U-Lock Compatible**
Designed for use with standard Doc Johnson Vac-U-Lock attachments and compatible accessories.

### Best Surfaces

For maximum suction performance, use on clean, smooth, flat, and non-porous surfaces such as:

* Glass shower doors
* Glossy ceramic or porcelain tiles
* Mirrors
* Polished stone
* Smooth metal
* Other sealed, non-textured surfaces

The base may not perform correctly on grout lines, textured tiles, painted walls, wood, porous stone, or uneven surfaces.

3. Switch on the electronic vacuum system.
4. Wait until the display confirms that sufficient vacuum pressure has been reached.
5. Check the attachment and suction strength before every use.
6. Keep the electronic vacuum system powered on while the product is in use.
7. Release the vacuum carefully before removing the base.

### Important Safety Information

Always inspect the product, attachment, surface, and vacuum level before use.

Actual holding performance depends on the mounting surface, cleanliness, angle, applied force, attachment size, and operating conditions.

Do not exceed the stated tested load. Avoid sudden, jerking, sideways, or shock-loading forces.

This product is not intended for overhead mounting, climbing, fall protection, full-body suspension, or supporting a person’s body weight.

Never place yourself in a position where loss of suction could cause injury. Stop using the product immediately if the vacuum level becomes unstable, the battery is low, or the unit shows signs of damage.
