Compex Wireless USA 2.0 EMS & TENS Muscle Stimulator
The Wireless USA 2.0 is the top of the Compex range: the same complete ten-program set as the Sport Elite 3.0, delivered through four wireless pods instead of lead wires, with up to twenty hours of battery per charge. Nothing runs between the controller and your body, so you can move, stretch or keep training while a program runs.
Wellari Expert Take
Why Consider the Wireless USA 2.0?
Wires are the reason most muscle stimulators get used sitting still. Four leads running from a handheld unit to your legs means you stay where you are for the length of the program. The Wireless USA 2.0 removes that constraint entirely: each pod clips directly onto the electrodes and is driven by the controller, so the session can happen while you move around, stretch, or carry on with something else.
The second thing worth noticing is the battery. Twenty hours against eight on the wired units is not a marginal difference — it is the difference between charging monthly and charging as an afterthought. The trade-off is honest: this is the most expensive unit in the range, it has three levels of progression rather than five, and there are four pods to keep track of rather than a single tethered handset.
Best For
- Athletes who want the complete ten-program set without being tethered to a handset
- Anyone who wants to move, stretch or train while a program is running
- Users treating several muscle groups in one session across four independent pods
- People who want the longest battery life in the Compex range
- Buyers who found lead wires the reason a previous stimulator went unused
Wireless USA 2.0 Features & Buying Details
The ten programs, and when each is used
- Prewarm Up: does not contract the muscle; raises local blood flow before activity.
- Potentiation: applied briefly before an effort where speed and velocity matter.
- Endurance: targets slow-twitch fibres and resistance to fatigue.
- Resistance: an all-round program working both slow and fast-twitch fibres.
- Strength: the primary strength-building program.
- Explosive Strength: biased toward fast-twitch recruitment.
- Training Recovery / Active Recovery: used after ordinary training sessions.
- Competition Recovery / Recovery Plus: the deeper recovery protocol, used after hard efforts.
- Muscle Relaxation / Massage: a low-intensity comfort and relaxation setting.
- Pain Relief / TENS: nerve-level stimulation for temporary, localised comfort.
This is the same ten-program set as the wired Sport Elite 3.0. Compex names two of them two ways — Training Recovery is also Active Recovery, and Competition Recovery is also Recovery Plus.
The wireless pod system
- Pods: four wireless modules, each driving its own electrode placement.
- Control: handheld controller with integrated pad-placement guidance.
- Charging base: multi-pod charging station returns controller and pods to one place.
- Intensity: up to 999 levels; 3 levels of progression.
- Maximum frequency: 95 Hz.
Because each pod is independent, four separate muscle groups can run at once with intensity set individually. The pods are covered by the device warranty rather than the 60-day accessory term — an important distinction on a system of this value.
Power, charging and portability
- Battery: rechargeable, up to 20 hours of stimulation per charge.
- Charging: wall charger and multi-pod charging station included.
- Controller weight: 110 g.
- Controller dimensions: 106 × 68 × 20 mm.
Note that this unit charges from a wall charger and station rather than USB. If you travel frequently and want to carry one cable for everything, the Mini Wireless charges over USB instead.
What is in the box
- Compex Wireless USA 2.0 controller
- 4 wireless electrode pods
- 8 × 2" × 2" snap electrodes
- 4 × 2" × 4" dual snap electrodes
- Wall charger
- Multi-pod charging station
- Carrying case
- User guide (downloadable from Compex)
Twelve electrodes are supplied in total — eight small and four large. This is the largest electrode set of any Compex kit we carry. Electrodes are consumable and are the item you will re-order over time; replacement options are listed further down this page.
Warranty, support and safe use
- Device warranty: two years, extended to three years if the device is registered with Compex.
- Coverage: for the wireless device the warranty covers the stimulator, the modules (pods) and the charging base.
- Accessory warranty: 60 days, covering the carrying case, charger and electrodes.
- Claims: handled directly by the Compex claims department.
The pods and charging base being inside the main warranty rather than the accessory term is worth knowing — they are the components most likely to matter over a multi-year ownership. Wellari's own returns and support terms are separate from the manufacturer warranty and are set out in our store policies.

Replacement Electrodes for This Device
The Wireless USA 2.0 uses both Compex Easy Snap sizes and ships with twelve electrodes. They are the consumable you will re-order. Compex lists this device as compatible with:
- 2" × 4" Dual Snap — single pack (2 electrodes) — the large pad, for quadriceps, hamstrings, glutes and lower back.
- 2" × 4" — 5 pack (10 electrodes) — better value per pad if you train regularly.
- Smaller 2" × 2" pads, which this kit uses eight of, are in the full Compex range.
Compex covers electrodes under its 60-day accessory warranty. The pods and charging base are covered by the two-year device warranty.
Common Questions
How many pods and electrodes are included?
Four wireless pods and twelve electrodes — eight 2" × 2" snap electrodes and four 2" × 4" dual snap electrodes — plus the wall charger, charging station and carrying case.
How does it differ from the Sport Elite 3.0?
The programs are identical: both run the same ten. The Wireless USA 2.0 delivers them through four wireless pods rather than four lead wires, and its battery lasts up to twenty hours rather than eight. The Sport Elite 3.0 has five levels of progression against three here, and charges over USB.
Are the pods covered by the warranty?
Yes. For the wireless device the manufacturer warranty covers the stimulator, the modules (pods) and the charging base. Accessories — carrying case, charger and electrodes — carry a 60-day term.
Can all four pods run at the same time?
Yes. Each pod is independent, so several muscle groups can be worked in one session with intensity set separately for each.
What is the difference between EMS and TENS?
EMS sends impulses that make the muscle itself contract, which is why it is used for preparation, conditioning and recovery. TENS works at the sensory-nerve level and does not contract the muscle; it is used for temporary, localised comfort.
Can I use it if I have a pacemaker?
No. Do not use this device if you have a pacemaker, an implanted defibrillator or any other implanted electronic device unless a qualified healthcare professional has specifically cleared you to do so.

Where the manufacturer's own published material was not consistent, we have left the specification off this page rather than choose between two figures.
