What is the point to 2 USB ports and 2 ports cigarette lighter if the case is not capable of recharging itself nothing but an iPhone when it is running. The problem is that the maximum current is 500mA, it would take a minimum of 1A for it to work properly, or when you have to cut the devices that we want to ensure a minimum charge load.
Basically if you have your smartphone with gps for coyote and turned on and you connect, this box will only slow the discharge your battery not charging. (This also depends on your mobile, some are pumping less battery than others)
