While preparing all the stuff for making a turn around the world I had to get a power source to get energy to all my devices. So the first powerbank I ordered was not available for the last 2 weeks. The time is running down to the take off so I decided yesterday to get another model of a 20000mAh power bank. This thing is a beast 539gr heavy but really slim and comfortable to carry in a backpack. With this beast there is no device getting low power anymore. A digital display shows you the percentage of the remaining energy.
