AVCOO 3-in-1 TENS Unit with EMS & Relax — Rechargeable Pocket Stimulator, 32 Modes & 40 Intensities, EVA Case

The AVCOO 3-in-1 TENS Unit is a compact, rechargeable electrotherapy device that combines TENS, EMS, and a relax mode to help manage muscle discomfort across multiple body areas without drugs.

This pocket-sized stimulator pairs dual-channel control with 32 therapy modes and up to 40 intensity settings to let you customize sessions for shoulders, back, knees, neck and more. The kit arrives ready to use — with a travel case, two pad sizes, leads, USB cable and a battery designed to run for many treatments between charges. Pads are latex-free and rated for repeated use, and the device includes a battery level indicator so you can avoid unexpected interruptions.

How does the AVCOO unit deliver different therapy styles?

The device integrates three distinct electrical therapy options so you can choose the sensation and effect you prefer: TENS for nerve-focused pulse stimulation, EMS for muscle contraction, and a RELAX mode that alternates patterns for a soothing feel. Mode selection is simple and the dual channels allow varied settings on separate electrode pairs.

• 32 pre-set program patterns for diverse pulse rhythms
• Independent A/B channels so each pad pair can run its own mode and intensity
• 40 incremental intensity levels for fine-tuning comfort
• Mode icons and battery indicator for clear session control

What comes in the kit and how do I use the pads correctly?

The AVCOO bundle contains everything needed for home and travel use: the stimulator, an EVA carry case, 12 electrode pads in two sizes, a pads holder, two lead wires, USB charging cable and a user manual. Apply clean, dry skin, position pads around the painful area, plug in the leads, and begin with low intensity to find a comfortable level.

• 12 pads (four 2x4" rectangles and eight 2x2" squares) for targeted coverage
• Latex-free gel pads that last for 50+ uses when cared for properly
• Use smaller pads for ankles/neck, larger pads for shoulders/waist
• Includes holder to store pads and extend adhesive life

How long does the battery last and how is the device charged?

AVCOO built a high-capacity rechargeable lithium battery intended to deliver extended runtime—up to roughly 20 hours of cumulative use—so you won't need constant recharging. A standard USB cable allows charging from wall adapters, power banks or laptop ports, and an onboard battery indicator shows remaining charge.

• Approximately 20 hours total run-time between full charges
• USB charging works with wall chargers and power banks
• Battery-level indicator prevents mid-session surprises
• Compact size makes it easy to charge on the go

Is the AVCOO safe and what maintenance does it need?

The electrode pads are crafted with a latex-free gel and meet CE, RoHS and FDA standards, reducing irritation risk for most users. To preserve pad life, clean skin before application, store pads on the protective film between sessions, and replace adhesive pads once they lose tack or cleanliness.

• Compliant with CE, RoHS and FDA safety standards
• Latex-free gel minimizes allergic reaction potential
• Store pads in the included case and on their protective liner
• Replace pads after adhesive deterioration or contamination
