Features

[Safety & Intelligence] - Compared with traditional manual suction cups, this smart suction cup can automatically stop/suction. When the pressure reaches the set maximum pressure value (40kpa) after startup, the suction cup will automatically stop, and the object can be safely lifted for operation; If the air pressure is below 40kpa during use, the suction cup will automatically start to inhale. So you don't have to worry about safety issues.

[Real Time Pressure Monitoring] - The pressure gauge shows the pressure of the suction cup in real time. When the pointer enters the green zone, it indicates sufficient pressure for use. Once it enters the red zone, the suction cup will automatically replenish the pressure until the pointer returns to the green zone, which can prevent falling.

[Thickened Three-layer Design] - Our upgraded vacuum cup adopts a thickened three-layer design, which has stronger suction force, longer adsorption time, more sealing, and safer than single-layer suction cups.

[Easy to use] - Simply press the button gently, the vacuum suction cup can quickly and automatically suck air. After use, press the switch twice quickly to release pressure. No manual operation is required throughout the use, simple and labor-saving.

[Rechargeable Lithium Battery] - The electric suction cup is equipped with a 3000mAh high-capacity rechargeable lithium battery, which takes only 2.2h to fully charge once and can be used for more than 8 hours. In addition, the push-pull battery design and battery power percentage display make it more convenient to use.
