All the samples comes with a not EU wall socket so I have to test them with the Neo wall charger
Don't even able to charge the neo shotted down or suspended
in spite specifications claims 3000mA it can only charge the 1200mA Neo batterie once and the second try it only charge 1/3 , and it takes more than 4h to do the full charge in spite of Neo detect it as 1000mA/h power source, and neo must be suspended or no charge, only mantains the internal battery at same level if Neo is on.
Instruction only in Chinese and the lack of compatible wall socket make me unable to test it cause it not use a mini USB and I have no adaptors aviable.
The product 'Solar Gorilla' is a polycristalline foldable module. I've used it for a XO computer (with a converter) and now for my FreeRunner (without). It has a USB output which delivers enough electricity. The FR doesn't need to be forced to 500mA. The module has an output of 10W, which is more than enough. Unfold, I can attach it to my bicycle. I also use a small lectern to hold it on a table.
