For someone like me who. As a jazz musician, and more recently as an author a lot and therefore must be constantly online, is the Power Bank "ninetec" a valuable aid Their high load capacity and its diverse usability offer independence over longer periods and ensure security, which allows an undisturbed concentration on the daily operations. In addition, the Power Bank can be carried along easily because of their sleek size, this is visually presentable and therefore positively apart from many devices, which are often perceived as a nuisance. "Ninetec" is indispensable for me.
