Hi,
 Just receive my solar charger bought on Ebay. The output voltage is 5.5V on USB port. Is  Arduino USB port safe to work with voltages higher than 5V? My plan is to  use  it with my Arduino Pro Mini, and Megas...


here´s the charger:

5.5V is just OK.  The absolute maximum for the chip is 6.0V I believe.  You may find it outputs a bit less under load.  Connect it and measure the 5V pin on the board and see.
