Warning: Never plug the charger into the socket like this… see more
Why phone chargers can be dangerous:
Phone chargers are designed to safely convert the electricity from your wall outlet to the lower voltage your smartphone needs.
Under normal circumstances, this process is completely safe.
The problems start when the chargers:
Damaged,
poor quality,
incorrectly placed
, covered during charging
, used with overloaded outlets:
when these conditions occur together, chargers can become excessively hot.
Heat is the greatest enemy of electrical equipment.
Although most modern chargers have built-in safety features, no device is completely immune to abuse.
The most common mistake:
One of the biggest mistakes people make is letting the charger hang loosely from the socket, while it bears the full weight of the charging cable.
Over time, this can lead to:
Loose output terminals,
damaged internal wiring,
bent terminal pins,
resulting in poor electrical contact
. Poor electrical contact causes resistance.
Resistance generates heat.
The heat poses risks.
Although this usually poses no immediate danger, repeated stress over months or years can damage both the plug and the charger.
Another dangerous habit: charging under the pillow.
Many people place their phone under their pillow while sleeping.
Others leave the charger itself covered with blankets.
It is much riskier.
Chargers naturally produce heat.
If it is wrapped in fabric, this heat cannot escape properly.
The temperature inside the charger may continue to rise.
Most quality chargers reduce the power or switch themselves off if they get too hot.
Cheap, counterfeit chargers often lack these security features.
Why cheap chargers are riskier:
Not all chargers meet the same safety standards.
Very cheap counterfeit chargers often save money by omitting essential safety components.
This may include the following, among other things:
Temperature protection,
overcurrent protection,
overvoltage protection,
good insulation,
certified materials
. As a result, they can overheat much faster than certified chargers.
Therefore, electrical safety experts recommend purchasing chargers from reputable manufacturers.
Saving a few euros is never worth putting expensive appliances – or your home – at risk.
Damaged charging cables are a warning sign.
Many people continue to use cables even after the outer layer starts to tear.
This makes the internal wiring visible.
A damaged cable can:
A short circuit
causes sparks,
overheating, damage
to the phone
, and a mild electric shock.
If any wires on your cable are exposed, replace them immediately.
Electrical tape is not considered a permanent repair.
Extension cords can cause problems.
Another common mistake is connecting multiple powerful devices to the same extension cord.
Imagine that you are charging:
Two phones,
a laptop
, a tablet
, a heater,
a kettle
, all plugged into a cheap power strip.
The belt may be overloaded.
Overloaded extension cords are one of the main causes of electrical fires in homes.
Always check the capacity of your extension cord.
Water and electricity never mix.
Many people charge their phones in the bathroom.
Some people even leave their chargers plugged into the socket near the sink.
Water significantly increases the risk of electrical accidents.
Although phone chargers operate at a relatively low voltage, the current that powers them carries dangerous household electricity.
Never use wet hands to touch chargers.
Never leave chargers in places where they can get wet.
The problem with fake fast chargers:
Fast charging has become hugely popular.
Unfortunately, counterfeiters know this.
Fake “super-fast” chargers are being sold everywhere on the internet.
They often advertise unattainable loading speeds.
Internally, however, many of these devices use inferior components.
Some systems are unable to regulate the voltage correctly.
Other systems do not have adequate thermal management.
Using one of these chargers can shorten your battery life or permanently damage your phone.
Is charging at night safe?
This question has been debated for years.
For modern smartphones, charging overnight is generally considered safe when using certified chargers and cables.
Modern phones automatically stop charging as soon as the battery is fully charged.
Instead of continuously charging the battery to 100%, they carefully monitor the battery condition.
However, this presupposes the following:
The charger is original.
The cable is undamaged.
The phone has adequate ventilation.
Nothing covers the charger.
If these conditions are met, charging overnight is generally not a risk.
Heat is the real enemy.
Almost all charging problems are related to heat.
