This Power Bank is handy and elegant in shape. Packed is the part (along with its USB charging cable and a manual) in a small cardboard box. The dimensions of the box are 8,3cm x 13.3cm x 4cm. These measures can I find more important than the sheer mass of the device for daily use of the power bank, because one always needs the charging cable to it, and this is usefully transported in the box. And since I've been an important suggestion: The cable is available under the thermoformed plastic holding cup stashed in the box: PRACTICAL would it be if the Holder would have a recess for the cable next to the space for the device. So one would not always when removing the parts somewhat cumbersome rumfingern (therefore a star deduction) Capacity: My smartphone (battery 1500mAh) I could once fully, and recharge the second time only to 30%. After the Power bank was empty. This does not meet the specified 3200mAh (which is why the second star deduction) UV lamp: Well, really important for daily life I would find a lamp with "plain white" light helpful. But who wants to check notes or documents more often, or urine on seemingly clean surfaces examined, taking well to appreciate probably more.
