It's one of the first things we do in the morning--pull the cell phone off the charger.
Well if yours is a knock off, it could be a fire hazard.
Katie Skerchock found that out first hand when she unplugged her phone from its charger and says she heard an explosion.
"I stopped a second, and I look down and see the sparks," she says.
She says a metallic covering over her USB cord shorted out.
In a recent lawsuit posted by tech blog patentlyapple.com, Apple claims that it purchased and tested more than "100 iPhone devices, apple power products, and lightning cables sold as genuine by sellers on Amazon.com."
The company says 90 percent were fakes with design flaws that create "..risks of overheating, fire, and electrical shock."
So how can you tell if your charger is really Apple certified?
The company says for products made by a third party, the proof is in the packaging.
Apple certified accessories always have the "made for" or "MFi logo" on the packaging.
Genuine Apple lightning USB cables will show the words "Designed by Apple in California", and either "Assembled in China," "Assembled in Vietnam," or "Indústria Brasileira"
That information will be followed by a 12-digit serial number.
