The electronic muscle and nerve stimulator inSPORTline Zapster is a modern wireless electric stimulator designed to relieve tension, support muscle recovery, and activate muscles. Thanks to the combined use of TENS and EMS technologies, it offers a wide range of applications, from relaxation and relief of strained 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 promoting a feeling of relaxation. On the other hand, EMS programs 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 there is fatigue or muscle overload.

60 programs and adjustable intensity:

The device offers a total of 60 programs, divided between TENS, EMS, and relaxation. The stimulation intensity can be adjusted in 25 levels, allowing each user to easily choose the optimal pulse strength according to their personal sensitivity and current needs. The maximum pulse frequency reaches up to 102 Hz, depending on the selected program.

Wireless convenience and high-quality electrodes:

The wireless design ensures maximum freedom of movement and comfort during use at home, in the gym, or while traveling. The high-quality electrodes with excellent adhesion remain securely on the skin and allow targeted stimulation of different muscle groups.

Long-life rechargeable battery:

The rechargeable polymer battery provides up to 15 hours of operation on a single charge. Charging takes about 2 hours using the included USB cable, ensuring the inSPORTline Zapster is always ready for use, even when away from home.
