The Percelos Core is a rechargeable foot and leg stimulation device designed to support everyday comfort and relaxation from home. It combines TENS nerve stimulation with EMS/NMES muscle stimulation and offers 10 modes and 20 intensity levels, allowing you to personalise each session.

• EMS — Electrical Muscle Stimulation: uses controlled electrical impulses to activate motor nerves, encouraging muscles to contract and relax.
• NMES — Neuromuscular Electrical Stimulation: stimulates the nerves responsible for activating muscles, producing controlled muscular contractions.
• TENS — Transcutaneous Electrical Nerve Stimulation: delivers gentle electrical impulses through the skin to stimulate sensory nerves and may help alter how discomfort is perceived during use.

No. The Percelos Core uses electrical stimulation rather than vibration, rollers, kneading or shiatsu massage.

You may experience tingling, pulsing, tapping or rhythmic muscle tightening in your feet and lower legs. The sensation should be noticeable but comfortable. Begin at the lowest intensity and increase it gradually. Stop using the device if the stimulation becomes painful or causes unexpected discomfort.

The Percelos Core has a 30-minute automatic timer. The device switches off automatically at the end of the session. Always follow the instructions and recommended usage guidance provided in the user manual.

Yes. Both bare feet should be placed fully on the contact pads while you are seated. Ensure your feet and the device are clean before use.

No. The Percelos Core should be used while seated. Do not stand, walk or place your full body weight on the device.

The Percelos Core operates silently because it uses electrical stimulation rather than mechanical vibration or moving massage parts.

No separate gel, cream, or replacement foot pads are required for normal use. Place your bare feet directly onto the integrated contact areas.

The device can be operated using its on-device controls or the supplied wireless remote control. The remote requires two AAA batteries, which are included. To turn the device on, you must always press the power button on the device.

The Percelos Core contains a rechargeable battery and is charged using the supplied USB-C cable. Follow the charging instructions in the user manual and do not use a damaged cable, connector or charging port.

• Switch the device off and disconnect it from the charging cable
• Wipe the surface with a clean, soft cloth
• Do not immerse the device in water or rinse it under a tap
• Do not use abrasive cleaners, solvents or harsh chemicals
• Keep liquids away from the controls, display and charging port
• Store the device in a clean, dry place away from direct sunlight and excessive heat
• Do not place heavy objects on top of the device
• Inspect the device and charging cable regularly for damage

Do not use the device if you have a pacemaker or another implanted electronic device. Speak with an appropriate healthcare professional before use if you are pregnant, have epilepsy, a heart condition, serious circulation difficulties, reduced sensation or another medical condition that may make electrical stimulation unsuitable. Do not use the device on broken, irritated, infected or significantly numb skin. Always read the complete safety information in the user manual before first use.

No. The Percelos Core is not a substitute for medical assessment, diagnosis or treatment. Seek advice from an appropriate healthcare professional regarding persistent, severe or unexplained symptoms.

• Charge the device using the supplied USB-C cable
• Check that the cable is securely connected
• Try a suitable alternative USB power source
• Check the charging port and cable for visible damage
• Follow the power-button instructions in the user manual

Do not continue using the device if the charging port, cable or device appears damaged.

• Ensure both bare feet are placed fully on the contact areas
• Confirm that an operating mode has been selected
• Begin at the lowest intensity and increase it one level at a time
• Reposition your feet to improve contact
• Make sure the surface of the device is clean and dry

Sensitivity varies between individuals, so a higher or lower intensity may be required to produce a comfortable sensation.

Reposition both bare feet so that they are making full and even contact with the pads. Differences in skin contact and sensitivity can make the sensation feel stronger in one foot than the other. Reduce the intensity if the sensation feels uncomfortable.

• Check that two AAA batteries are installed
• Confirm that the batteries are inserted with the correct polarity
• Replace the batteries if necessary
• Make sure the device is switched on
• Try operating the device using its on-device controls

This is normal. The Percelos Core includes a 30-minute automatic timer and switches off when the session has finished.

• Check that the charging cable is securely connected
• Try another compatible USB power source
• Inspect the cable and charging port for damage or debris
• Allow the device sufficient time to charge

Stop using the device and contact Percelos Support if it becomes unusually hot, produces an unusual smell or appears damaged.
