Test reveals sizeable differences between solar-panel chargers

Nowadays you're able to charge your cellular phone with the help of sunlight. But there are huge differences in the amount of electricity you can generate. 

By appointment of Testfakta, the PZT laboratory in Germany has tested eight portable solar chargers designed for camping and the outdoors. The selection of products was made with relevance to the Swedish market place. The lab has measured the capacity of both, the solar cells and the accompanying power-banks, looked into the technical differences, as well as into handling and safety.
