For outdoor use - nothing that could scratch. Connections are again under a plastic Kläppchen and the whole thing really seems as if it would not break when dropped. Handy, slightly larger than a cigarette lighter. Fits comfortably in your hand. Feels good, soft to the touch. Easy. For the size and load capacity (I have the mit2600 mAh) comes with a lot of real rum. I could my iPhone 4 almost 2 x completely recharge it (was respectively at approximately 20% down) once again to 100% and the next time, at least not at 70%. And loaded the particles is also fast again, in just over 2 hours. Included is a short charging cables and detailed instructions in English.
