Neither male nor devices (or their batteries) are noticeably warm, although the shop is in a reasonable time.
The plug is wonderfully small and handy, fits just fine into the glove compartment and you can at any time all USB charging enabled devices at least in part load (depending on the length of the journey). I think it's very comfortable and have my chic 4-port connector now always on board!
For functionality comes here but also the attractive design and high quality workmanship. Since few words remain, only five stars!
