David Hanak In connection with the Apple Watch, many users talk about one drawback, which is the weaker battery life. Over the generations, Apple has gradually improved the watch's battery life, but it is still far from ideal. The authors of the Kickstarter campaign decided to change that, in which they offer a strap that contains a battery that extends the life of the Apple Watch.
Although a battery-powered wristband is certainly a good idea, we don't see them much in practice, as something similar is strongly discouraged by Apple within the framework of regulations and recommendations for the use and manufacture of Apple Watch accessories. The battery bracelet is susceptible to damage and possible injury to the wearer, and therefore Apple is trying to discourage manufacturers from this idea.
However, a bracelet appeared on Kickstarter that should solve all the potential problems with the charging bracelet and should be both completely reliable and safe, and should not interfere with the watch's sensory capabilities.
Togvu presents its band called Batfree as the world's first battery-powered wristband for Apple Watch. The basic pledge in which you get the bracelet is currently worth $35, but is limited in quantity. Next levels are understandably more expensive.
The Barfee bracelet contains an integrated battery with a capacity of 600 mAh, which is supposed to extend the life of the Apple Watch by about 27 hours. With a little effort, you can use the Series 4 for three days without needing to charge.

Charging is wireless and works thanks to the presence of a charging pad on the bottom of the bracelet. The presence of the bracelet should not in any way limit the function of the heart rate sensor, because it has a cut-out in it, thanks to which the sensor works. The question remains, however, to what extent it will retain its accuracy. In addition to charging, the bracelet also has a protective factor, as it will serve as a cover for the body of the watch. The bracelet is compatible with all generations of Apple Watch, except for Series 0 and 1.
