Meet the inCharge Bolt: a small keyring cable that lets you charge your smartphone quickly. It is weather-resistant and lets you charge at up to twice the speed of a regular cable. The inCharge Bolt has a magnet closure, so you can take it with your keys anywhere you go. You will be able to charge Lightning or Micro USB devices with this.
The inCharge Bolt is affordable and compatible with most smart devices on the market. It will be available in 8 colors. You can find out more on Kickstarter.
