And it's not just portable power packs with issues: Inexpensive third party power bricks and phone cords have shorted and caught fire, as Katie Sherchock told me last year.
"I just head an explosion," she said. "And I stopped a second and said 'what was that?' And I look down and see the sparks."
What you can do
So how can you protect yourself?
Apple suggests you buy only Apple certified chargers and cords. Certified accessories will have an "MFi" logo indicating that Apple has checked them for safety.
If you have a third party charger or power pack, you may not want to use them when you are sleeping.
Never recharge or use a third party power pack while flying on an airplane. Some airlines now warn against using these, or even checking them below in luggage.
Both Katie Sherchock and Jeanie Capiello say they will stick with Apple approved chargers from now on.
What might have happened if no one had been home when hers overheated? Capiello says, "We were this close to going out to dinner that night, and if that had happened, I don't think the firemen could have gotten there soon enough."
A spokesman for iLive's US distributor, Good Bay, told us they have had no previous issues with this model. He says all their products are certified by either UL or CE, the European commission.
But the company will investigate, so that you stay safe and you don't waste your money.
