Our Thumpr® A4 PRO Sex Machine is a powerful, fully automatic machine designed to combine exceptional stability, smooth performance and outstanding positioning flexibility.
Powered by a high-torque 120W motor, the A4 PRO delivers strong, consistent movement with variable speeds of up to 300 strokes per minute. Its generous adjustable stroke length of 3–15cm allows you to control the depth of movement, from shorter, more controlled strokes through to a full 15cm range.
One of the standout features of the A4 PRO is its highly adjustable all-metal frame. The operating height can be adjusted from approximately 7.5–44cm, while the angle can be positioned between 0–90°, providing excellent versatility for different positions and setups.
The A4 PRO also features a double-ended design, allowing attachments to be connected at either end of the machine. It can be configured for individual use with a single thrust rod or operated from both ends simultaneously for couples, providing considerably more versatility than a conventional single-ended machine.
Built from durable 7075 aluminium alloy and stainless steel, the A4 PRO has a reassuringly solid 9.14kg assembled weight. Two heavy-duty T-shaped support frames provide a stable base, while reinforced bearings and a precision sliding mechanism provide smooth and reliable operation.
Despite its powerful motor and substantial construction, the A4 PRO is engineered for exceptionally quiet operation, with a manufacturer's stated maximum sound level of approximately 38dB.
Operation is kept simple with a wired speed controller. The precision dial controller provides continuous variable speed adjustment, allowing the pace to be increased or decreased easily throughout use.
The A4 PRO comes standard with our Clic Loc™ quick-change attachment system, providing a secure anti-rotation connection and allowing compatible attachments to be changed quickly and easily.
NB: If you wish to use your favourite Vac-U-Lock™ dildo and/or suction cup dildo, we have a selection of compatible Clic Loc™ adaptors that can be purchased separately.
