The Electronic Muscle & Nerve Stimulator inSPORTline Zapster is a modern wireless electrical stimulator designed to relieve tension, support muscle recovery, and activate muscles. Thanks to the combination of TENS and EMS technologies, it offers a wide range of uses—from relaxation and releasing overworked muscles to targeted muscle stimulation. It is suitable for use before, during, and after exercise.
Combination of TENS and EMS for comprehensive care
- TENS = Transcutaneous Electrical Nerve Stimulation
- EMS = Electrical Muscle Stimulation
TENS technology focuses on nerve stimulation, helping to relieve tension and promote a feeling of relaxation. EMS programs, on the other hand, activate muscle fibers, improve blood circulation, and support muscle recovery. Thanks to this combination, the inSPORTline Zapster is ideal for both athletes and everyday use when experiencing fatigue or muscle overload.
60 programs and adjustable intensity
The device offers a total of 60 programs, divided into TENS, EMS, and relaxation modes. Stimulation intensity can be adjusted across 25 levels, allowing each user to easily select the optimal pulse strength based on personal sensitivity and current needs. The maximum pulse frequency reaches up to 102 Hz, depending on the selected program.
Wireless comfort and high-quality electrodes
The wireless design ensures maximum freedom of movement and comfort during use at home, at the gym, or while traveling. The high-quality electrodes with excellent adhesion stay securely on the skin and allow targeted stimulation of different muscle groups.
Rechargeable battery with long operating time
The rechargeable polymer battery provides up to 15 hours of operation on a single charge. Charging takes approximately 2 hours using the included USB cable, ensuring the inSPORTline Zapster is always ready for use, even away from home.
