Jet Blue and United Airlines do not accept already hoverboards in carry-on or checked luggage. All sort of such devices are banned because their producers don’t provide the exact technical specification about the battery. This decision may be unpleasant for some people but on the other part the considered risk is not at all to neglige.. Hoverboards, those futuristic-looking, electric powered hands-free skateboards, are a high risk product. Authorities in Lafitte, Louisiana, are investigating a home fire generated by a such device. Similar incidents were reported in Alabama, Florida and Hong Kong. Warning were issued also in the British capital, London, Europe. However, Justin Bieber is riding one and they’re one of the most-wanted sports items on Amazon.
