We were able to test the device in Croatia and Italy again. With capricious weather and overcast skies, the current consumption is by far not satisfactory, but you should know that even before the purchase of a 7W panel. We have drangehängt smartphones partially right on solar equipment, as our battery pack was not at hand. The LG Nexus 5 and Samsung Galaxy S3 Mini loaded perfectly. Even with passing clouds after the loading operation was continued without any problems (even partially in second cycle). Our Nexus 7 Tablet (1st generation) could not be loaded during operation of your tablet. Here the consumption of the tablets will probably be too high. But it was also not a criterion for us. Charging in the off state of the tablet was also successful, but you already need here the odd coffee. Exact times have not been obtained.
All in all it is a nice gimmick. We are concerned as an alternative and testing equipment for any more panels. Quite to this power source I would not leave me. But if you just want to invite his cell phone and traveling in areas where the weather is expected to be sunny, gets a great performance for the price. The processing of the panels has also been mentioned here and is looking a bit dingy from, but should not deter further. The protective film has stayed with me up, otherwise the company would have to give an indication if something would remove.
