Thumpr® A4 PRO Sex Machine Power, Stability and Adjustable Positioning

We believe that a great sex machine should be powerful, stable and easy to adjust. The Thumpr® A4 PRO Sex Machine has been designed for exactly that.

Built with a strong all-metal frame, a powerful 120W motor and a highly adjustable setup, the A4 PRO gives you smooth automatic movement with plenty of control over height, angle and stroke length.

It’s perfect for you if you want serious performance, strong build quality and more ways to position the machine during use.

Thumpr® A4 PRO – powerful performance with height, angle and double-ended control.

Built for Powerful Performance

The Thumpr® A4 PRO is a fully automatic sex machine designed to deliver strong, smooth and steady movement.

Powered by a 120W high-torque motor, the A4 PRO can reach speeds of up to 300 strokes per minute, giving you plenty of power when you want it.

You can choose how much movement you want as it has an adjustable stroke length of 3-15cm, so you can keep it shorter and more controlled, or increase it for a fuller stroke.

This makes the A4 PRO a great choice if you want power, control and flexibility in one machine.

Adjustable Height and Angle

One of the biggest advantages of the A4 PRO is how adjustable it is.

The height can be adjusted from around 7.5-44cm, while the angle can be set between 0-90°. This means you have much more choice in helping you find a position that feels right for you.

Whether you want a lower position, a higher position or a different angle, the A4 PRO gives you more room to adjust than many standard machines.

Double-Ended Design

Another great feature of the A4 PRO is its double-ended design.

This means attachments can be connected at either end of the machine. You can use it with a single thrust rod to use on your own, or you can use both ends at the same time with someone else.

This gives the A4 PRO more flexibility than a standard single-ended machine and makes it a very versatile option in the Thumpr® range of sex machines.

Strong, Stable and Built to Last

The A4 PRO is built from durable 7075 aluminium alloy and stainless steel, giving it a strong and solid feel.

With an assembled weight of 9.14kg, it feels very stable during use. The two heavy-duty T-shaped support frames give the machine a strong base, while the reinforced bearings and precision sliding mechanism help keep the movement smooth and reliable.

It’s a machine that’s perfect if you want something sturdy, dependable and made to handle regular use.

Quiet, Smooth Operation

Even with its powerful motor and solid frame, the A4 PRO is designed to be quiet.

The manufacturer’s stated maximum sound level is around 38dB, making it much quieter than many people would expect from a machine with this level of power.

That quiet operation, along with the smooth sliding mechanism, helps the A4 PRO feel more refined and easier to use.

Simple Speed Control

The A4 PRO is easy to use with its wired speed controller.

The precision dial lets you increase or decrease the speed smoothly, so you can adjust the pace during use easily. You just need to turn the dial to find the speed that suits you.

This makes the A4 PRO easy to use while still giving you full control over the pace.

The Clic Loc™ System

The A4 PRO comes standard with the Clic Loc™ quick-change attachment system.

This gives you a secure anti-rotation connection and allows compatible attachments to be changed quickly and easily. Just snap the attachment into place and remove it when you want to change the setup.

If you want to use your favourite Vac-U-Lock™ compatible dildo or a suitable suction cup dildo, we also have a selection of Clic Loc™ adaptors available separately.
