Frequently Asked Questions
Why does the Kongzee have 40 intensity levels?
Most TENS units have 20 intensity levels. The Kongzee doubles this to 40, allowing much more gradual and precise adjustment. This is particularly useful for period cramp simulation where you want to slowly increase from barely noticeable to intense stimulation, mirroring the 10-level pain scale on our free simulator.
What is DIY mode on the Kongzee?
DIY mode allows you to manually set the pulse frequency (in Hz), pulse width (in microseconds), and cycle time. This gives you unlimited customization beyond the 24 pre-set modes. Advanced users can create their own therapeutic programs tailored exactly to their needs.
Is the Kongzee FDA cleared?
Yes — the Kongzee 4-in-1 is FDA cleared, which is the highest safety and efficacy certification for consumer medical devices in the United States. It is also FSA and HSA eligible.
