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 secon 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
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.
