Blah, blah, a little disappointed by the product. I bought it mainly for its small size (so I can close the cover of my cigarette lighter plug leaving) and that side no worries! But the power output of the charger is too low! I bought it to use my Galaxy S3 in GPS mode for several hours, but even plugged the battery decreases (slower course, but it decreases). And that's not a problem with my phone or my cigarette lighter, as my previous charger did not have that problem.
