inCharge is a cheap, keyring-sized USB cable
inCharge - the smallest keyring cable: charge your iPhone, Android device, or Blackberry wherever you go.
A tiny cable at a tiny price. It works with both microUSB and Lighting ports, and perhaps even more exciting is that it can charge at twice the speed of a regular phone charging cable. That’s pretty handy when you’re in a rush.
inCharge is a flexible charge and sync cable that’s just an inch tall when folded. It has a magnetic clasp so you can easily fold it around a keyring.
Available in Lightning and microUSB. Only $ 12 Bucks
