The Insmart TENS unit is a rechargeable four-channel muscle stimulator that combines TENS pain relief, EMS muscle training, massage and a DIY frequency mode in one device. It offers 60 modes and 30 intensity levels, with a 300mAh battery charged over USB-C and a timer from 10 to 90 minutes. Four channels let you treat more areas at once than the two-channel units most rivals sell at the entry level. It suits people managing back, neck, joint or menstrual pain at home and anyone doing basic muscle rehab, though the many modes take some learning.

The Insmart TENS unit is a rechargeable device that combines four functions: TENS, EMS, massage and a DIY mode. It works with 2 channels or 4 channels and offers 60 modes and 30 intensity levels. It uses a TENS method that imitates manual massage and is non-invasive and drug-free.
TENS mode (P1-P20) is for chronic and acute pain such as sciatica, joint pain, back pain, leg pain and menstrual pain. EMS mode (P20-P40) uses electrical pulses to train muscles. It can be used for muscle strengthening and rehabilitation, and to help prevent muscle atrophy. Massage mode (P40-P59) relaxes muscles with massage-like pulses. In DIY mode (P60), you choose the frequency yourself.
The unit is designed for easy use at home, in the office and while traveling. It is intended to help boost blood circulation and ease back, neck, muscle and general pain.
