Normally, the full charging my phone Samsung Galaxy S3 takes even when switched off via power about 8-9 hours. This device loads switched on my phone Samsung Galaxy S3 from 15% to 100% about 2,5 - 3 hours. And I can use it and contribute and not be verbundet to an electrical outlet. Unfortunately, there is only enough for a store: device then must be reloaded - for that it needs again only about 3 hours. My phone was full already loaded. Very fast loading, only recommendable!
