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.
The General Motors Pontiac brand has a long history. The line, which began early in the 20th century, took its name from an important historical figure. The end of the road is near for Pontiac. GM announced in April 2009 that it plans to discontinue the brand by the end of 2010. The name Pontiac was first used in 1893 by the Pontiac Buggy Co. The company later became the Pontiac Spring & Wagon Works Co. In 1906, Oakland Motor Car Co. merged with Pontiac Spring & Wagon Works. General Motors acquired both brands in 1909.
