Using their (both are mediabridge) cable directly into either usb port of the protector, I was only able to get usb charge. (It did provide full charge to ipad.) When using the samsung wall wart (one official and one oem knock-off), the cables provide ac charging.
Pontiac: Division of General Motors. Pontiac is a brand of General Motors and was the performance division of General Motors for years. However, its history could date back to the days of the horse and carriage. In 1893, Edward M. Murphy established the Pontiac Buggy Company in Pontiac, Michigan and founded the Oakland Motor Car Company in 1907.
Pontiac was a brand of automobile manufactured and sold by General Motors between 1926 and 2010. Introduced as a companion make for GM's more expensive line of Oakland automobiles, Pontiac overtook Oakland in popularity and supplanted its parent brand entirely by 1933. Sold in the United States, Canada, and Mexico by GM, Pontiac was advertised as the performance division of General Motors from the 1960s onward.
