The London Fire Brigade mentioned that such devices could actually burst into flames when one uses wrong charger, as evident by the victim of the fire who has since been hospitalized did. The fire took a quartet of fire engines and over 20 firefighters to deal with so that others around the flat remained safe and sound. The lady herself was treated by paramedics for smoke inhalation and shock, prior to being sent to the hospital.
E-cigarettes might not be able to set things alight by itself, but using the wrong charger does carry with it its fair share of risks. A spokesman from the Brigade Fire Investigation Team shared, “The danger is that people sometimes use incorrect chargers which runs the risk of over-charging, which can potentially have explosive results. We are calling on e-cig retailers to ensure they are selling the correct chargers for the cigarettes. As with all rechargeable electrical equipment, it’s vitally important that people use the correct type of charger for their e-cigs to prevent fires which can be serious and could even result in death.”
