This iPhone to Mini-USB power supply cable connects your iPhone 4/4S, or iPhone 3G/3GS (30-pin port) with the Sleek's Mini-USB port to simultanously charge and boost your phone.
Unfortunately, this power supply cable will NOT connect directly to iPhone 5/5s 6/6s phones, which use the redesigned 8-pin iPhone ports.
It will also NOT work with the Sleek 4G 813426, 813426-H, and 460107.
