The voltage is always around 9V. The charging curve can be divided into four parts. 

In the first part, the input power was around 18W for the first 7 minutes. After that, the power dropped to 14W and 11W in turn. Finally, the power slowly drops to almost zero. It takes 2 hours and 33 minutes to be fully charged.
