The Power Bank is just around only on the dashboard and is therefore now, in the summer, always fully charged and ready for use. Charging at the outlet works 1A and even relatively quickly. A few hours but already you have to plan. With a full charge, the Power Bank my smartphone, Samsung Galaxy S3, without recharging of the Bank, 2 times charged and was not then empty. For outdoor activities ie a guarantee of up to 3 charges. Three days away from any civilization, even without a lot of sun, were not a problem. The handling is easy. The MP-S6000 Solar Power Bank is built tough, lightweight and fits into any pocket. The included USB cable to the adapter extensive collection covers many possible device from which can be connected with it. The manual is poor. But ultimately understands the handling even without a manual. Around, a very good buy for me. Value = SUPER.
