EasyAkk is a recommendation

I have a Sony Z1 Smartphon and use it very often as a navi for hiking. InAbhängigkeit of the GP-use while navigating can go there after 5 hours, the battery capacity is running low. One need but the end is still to call Reserve. The EasyAcc is because the solution. With 9000 mAh can the Smartfon loosely 3 times load eg during a break. The decisive factor in the choice for this part was then also because of backpack suitability. There is shock and water resistant and you can at need even hanging from the outside of the backpack and making the shopfitting Smartfon stable carabiner is dabei.Die charge takes less than one hour at Total discharge of Smartfons who EasyAcc needs a couple of hours .Günstig this is a charger (Charger) with output 2.4 A DC or a double Charger 2.4 A and 1 A DC output. Since you can Smartfon and EasyAkk simultaneously load ie 10 in - 15 Watt. The compass gives you a child to play, he is not worth more. Too slow and too easily distract.
