Features:
Multi-functional & Professional:
This TENS electric massager features 6 modes and 19 intensity levels designed for targeted pain relief and muscle relaxation. Ideal for relieving discomfort in the shoulders, waist, back, neck, and limbs due to exercise, overwork, or daily tasks. It helps activate natural pain gate mechanisms, offering relief anytime with professional-grade electrotherapy.
Upgraded Hydrogel Pads:
The included replacement pads use advanced adhesive hydrogel for superior stickiness and extended use. They are easy to clean and compatible with most 2mm pigtail-style TENS electrodes available on the market.
Rechargeable & Long-Lasting Battery:
The device comes with a USB charging cable (adapter not included) and can be charged via wall charger, power bank, or laptop. One full charge offers up to 40 hours of use—more eco-friendly and longer-lasting than AA battery-operated models.
