Portable powerbank of 4000mAh to charge phones or tablets through USB or mini-USB output. The powerbank charges your devices with 5V/1500mA or 9V/1000mA. When you charge your powerbank from the wall it will give 5V/1000mA. As an emergengy solution, it can also be charged by it's small solar panel that gives 5.5V/180mA/1W. Beware that to fully charge such a huge battery from empty it will take at least 22 hours under optimal solar conditions so the solar panel is only a supplement for top-charging. The powerbank comes with 4 LED indicators to show it's power level.
