INFINITY Power: No more waiting around for charged batteries. 

Imagine coming home from a long, energy-sapping workout or after an exhausting day. Your body is longing to recover and the solution - a soothing compression massage with your COMPRESSION BOOTS - is just waiting to be utilised. But then the damper: the batteries are empty. It's a situation that is as frustrating as it is unnecessary. Thanks to the INFINITY BATTERIES KIT, waiting for batteries to charge is a thing of the past. 

The INFINITY BATTERIES KIT offers you 2 solutions: Firstly, you have a pair of spare batteries that work just like the standard batteries, except that they have twice the runtime. They also offer a practical solution if the spare batteries aren't charged: With a charging socket on the top of each battery, you can charge the batteries even during use: If the battery is about to run out, the 2-metre-long cable allows you to continue using your COMPRESSION BOOTS seamlessly while the battery is being charged at the same time. This guarantees that your recovery remains uninterrupted thanks to a continuous compression massage and optimally supports the regeneration phase after an intensive training session. 

With rechargeable batteries offering a capacity of 2000mAh, the INFINITY BATTERIES KIT ensures up to two hours of uninterrupted operation of your COMPRESSION BOOTS without cables - enough time to give your muscles the rest they deserve. 


The INFINITY BATTERIES KIT is extremely easy and convenient to use. If the battery in your COMPRESSION BOOTS runs low, you can use the replacement batteries in a flash. In the meantime, the discharged batteries are placed on the charger so that they are always ready the next time you need them. Thanks to their compact size, lightweight design and practical storage bag, the batteries are easy to take anywhere. 

Let nothing stand in the way of your regeneration with the INFINITY BATTERIES KIT. Forget waiting for charged batteries and instead enjoy instant recovery whenever you need it.

Continuous operation and battery charging during operation

Continuous charging is very simple: simply plug the two-meter-long USB-C charging cable into the charging socket on the top of the battery. Thanks to the continuous power supply, your COMPRESSION BOOTS not only remain in continuous operation, but the batteries also charge at the same time thanks to pass-through charging.
