eCoffee energyband uses TENS technology to stimulate the median nerve, naturally increasing heart rate variability (HRV) to help you stay awake, without the jittery side effects of stimulants and coffee.

For the best results, wear your eCoffee for 3 hours per day, 5 days a week, and 48 weeks a year.

eCoffee sends electrical pulses to stimulate the median nerve, which signals the brain to improve blood flow and increase neurotransmitter levels, boosting alertness and reducing fatigue. These effects are reflected in improved HRV (heart rate variability) values.
