Multiple U.S. 'e-sig' users have filed lawsuits alleging their battery-powered devices exploded and, in some cases, caused serious injuries.
Dozens of such suits have been filed in New York, Florida, and California, among other states, The Wall Street Journal reports.
E-cigarette models mentioned in lawsuits include those made by Chinese companies Sigelei, iPV Technology Co., and Kangertech.
In many cases, these malfunctions can be traced to the lithium ion batteries that power many e-cigarettes. Such batteries have been known to cause similar issues in other electronics. Most airlines, for instance, have banned hoverboards after several owners reported that their devices caught fire and exploded. Some iPhone owners have reported similar issues after charging their devices with third-party chargers not made by Apple.
The U.S. Food and Drug Administration also recently announced that it would begin regulating e-cigarettes as tobacco products.
