One portable muscle stimulator

Choose electrical stimulation for your goal

The KONGZEE 4-in-1 unit combines TENS, EMS, Massage and customizable settings. Choose a mode based on the type of stimulation you intend to use, then begin at the lowest intensity and follow the supplied manual.

TENS for sensory stimulation

TENS usually feels like steady tingling without a visible muscle contraction. It is commonly used as one part of a broader pain-management plan.

EMS for muscle activation

EMS stimulates motor nerves to produce controlled muscle contractions and may be used for muscle activation or recovery under appropriate guidance.

Massage and DIY settings

Massage presets offer additional pulse patterns, while DIY mode lets you adjust rate, pulse and cycle settings for a more personalized session.

4 therapy options TENS, EMS, Massage and DIY modes
24 presets Ready-to-select stimulation programs
40 intensity levels Gradual control from the lowest setting
Independent dual channels Separate A and B intensity controls
Rechargeable and portable USB-C charging with a carrying pouch
12 reusable pads Mixed sizes with standard 2 mm pins
