Hoverboards quickly gained attention in the market for their ability to transport its users around without them breaking a sweat, making the device quickly sought after. However, news now emerges that these two-wheeled gadgets have caused accidents for some after they blew up. 

According to Tech Times, the United Kingdom officials alerted those who are eyeing these self-balancing scooters this Christmas as a gift to themselves or for their loved ones, as they have "explosion risks." In fact, thousands of units have been confiscated in the U.K. after they failed tests, which showed that these e-boards have the tendency to explode and burst into fire.

This Christmas season, the sales of hoverboards have suddenly increased, but some reports suggested that some of the imported units have "poor quality" that can be hazardous to its users. Just this weekend, the retailers of car parts, Halfords, revoked all their Air Runner Balance Board units when they found that their £499 ($754) priced segways were sold in spite of having some plug and charger issues that didn't pass the U.K.'s standards.

CNBC reported the explosions were because the hoverboards were made with lithium-ion and lithium-metal batteries. If these batteries touched any metal object, like keys, coins or tools at both of its ends, which can cause extreme heat that will lead to a spark and then ends with a fire.
