One co-worker purchased a charger for his iPad at the Richmond Night Market. It worked for his phone but not for his iPad. The specs on the casing was "5.1V, 2.2A" which would meet the iPad's 5.1V/2.1A rating. The case was held together by two screws so we opened it up. The circuit board inside was marked "5V, 1A". Quick testing under load showed the output voltage dropped to 4.8V when drawing 1A which is within spec but trying to get 2A dropped the output voltage to 3V which is very out of spec. A waste of $8 for his original use but it works for his other devices. As the old saw goes, there's one born every minute.
