“Just like smartphones and electric cars, e-cigarettes contain lithium-ion batteries that can burst into flames or explode if pierced, damaged or overheated. In the video, the small silver vape is being overcharged at a higher voltage than it should be using an incorrect USB connector. The battery inside the vape can’t handle the higher voltage so enters a state of ‘thermal runaway’ and explodes wildly inside a protective Perspex container. The UK government also stresses the importance of using the right vape charger. It says on its website: ‘Only use the charger that was supplied with the vape for charging. Don’t charge your vape overnight and regularly check your device when it is charging. Unplug your vape when it is fully charged.'”
