Cheap and deformed power banks pose a risk of fire and explosion.
IT expert Vladimir Zykov stated that these devices behave like portable chemical reactors.
Inside the battery are a cathode, anode, and thin porous separator. Damage causes a short circuit, temperature rises rapidly, electrolyte boils, and flammable gases form. The casing then explodes and burns.
Swelling of the power bank is the most dangerous sign. Stop using it immediately.
