Need to keep in mind the possibility of self-explosion and spontaneous combustion of electronics?

Question

Electronics

Do refrigerators, smartphones, chargers, computers, cars written with electronics often explode and what devices explode and why?
Perhaps, devices with lithium batteries are more fire hazardous, which, when depressurized, react and light up.?

Answer 1

When using serviceable equipment with serviceable chargers, correctly laid wiring and normal mains voltage, the likelihood of an explosion or spontaneous combustion is extremely low. But not zero.
Most often, spontaneous combustion is caused either by physical damage to the partitions inside the battery (for example, due to a fall of a device with a battery or its severe obsolescence), or a significant excess of the supply voltage (breakdown of the mains voltage to the device).
In the first case, I know only one story where spontaneous combustion was associated with marriage - Galaxy Note 7. In general, in order to damage the battery so that it catches fire, you probably need to drive a nail into it. At least putting such a device on charge is unlikely to come to mind.
In the second case, cheap Chinese chargers are usually the culprit without sufficient protection between the network and the actual USB output. I can’t give an unambiguous recommendation here, but in general it’s better to use branded original chargers (Apple, Samsung).
In other cases, the probability of spontaneous combustion is very low.
With refrigerators, microwaves, TVs - pay attention to placement rules - the instructions usually indicate a safe distance from the walls so that there is enough air for cooling.
But - if you are calmer to turn off unused equipment from the outlet - it will not be worse for the equipment. And the switched off equipment will definitely not light up.

Answer 2

depends on the conditions of use :)
if the conditions of use coincide with those recommended by the manufacturer, then it is extremely rare.

Answer 3

What can explode in a refrigerator or computer? Perhaps a faulty capacitor, but even then it just pops, sometimes loudly :)
Lithium-ion batteries do sometimes explode, but this is preceded by damage to the case or excess charge voltage.
