The Power Bank is the optimal solution for any smartphone with poor battery life! Never again a blank smartphone device, when traveling and times no socket is ready. Small and portable, the Power Bank, fits in perfectly in the pocket and is very easy to handle. Can be plugged directly to the smartphone without Installierungen, so that the charging of the phone starts directly. Pleasant design, available in different colors, facilitates battery life with smart phones. Also very suitable for traveling. I would recommend the Power Bank with any smartphone!
