Have acquired the first of this article in another store 2 years ago. After about 4x charging and discharging but clearly capacity loss. After that was after 1x Smartphone each load of juice. In addition, within a few days showy self-discharge. My wife has one year later wg. contrary to my advice and so acquired the handy compact shape part. Unfortunately, she has had the same experience. Is thus not on the smartphone or a poorer product batch, but is apparently caused manufacturers.
