Bluetens V1 vs V2: what are the differences?

Do you own a first-generation Bluetens device and wonder what has changed? Or are you hesitating between the two versions before buying? Here is a clear comparison based on the official specifications of both generations.

What the two generations have in common

The V1 and V2 devices are based on the same principles: TENS electrostimulation for pain, EMS for muscles, control via the Bluetens app (iOS and Android), and more than 100 available programmes. The way you use them remains the same; what changes is comfort, power and day-to-day practicality.

Magnetic attachment: The V1 connected to the electrodes via a long snap cable. The V2 attaches directly and magnetically to the electrodes: simpler and quicker to put on, and more stable during the session.

50% more battery life. The V1 offered around 10 hours of use. The V2 goes up to 15 hours, still charging in 1 hour via USB-C (compared with Micro-USB on the V1).

20% more power. The V2 delivers more intense stimulation, particularly useful for muscle recovery and strengthening.

MDR certification. The V2 complies with the new European Medical Device Regulation (MDR), with stronger quality and safety standards.

Classic V2 or Duo Sport V2: what’s the difference?

Both devices share all the V2 improvements. The main distinction remains the same as between the V1 models: the Classic V2 is a single, versatile module suited to everyday use: pain, recovery, targeted strengthening. The Duo Sport V2 includes two independent modules that allow you to treat two muscle areas at the same time, with programmes geared towards sports performance. It is the natural choice for regular athletes: runners, cyclists, triathletes who want to make the most of every recovery session.

Should you upgrade to the V2 if you already have a V1?

If your V1 works, it still does its job. The V2 brings three practical everyday improvements: simpler and quicker setup (magnetic connection), improved battery life and more powerful stimulation. If you are about to buy, the V2 is the obvious choice.
