The charger of the tablet, the charger of the iPhone 14the charger Samsung Galaxy S22, the Motorola Edge 30 charger… and so we could go on forever. we have chargers USB above what is sustainable and, even so, we do not know how to differentiate when one is about to break.
If you have ever noticed that your iPhone or Android charger is hot after using it, you may be wondering why this is happening and if it is something to worry about. This is what you should know about it.
Some heat is normal in any USB phone or tablet charger. And this is because A charger converts alternating current (AC) power from your home outlet to direct current (DC) for your phone, generating heat in the process.
To perform AC/DC conversion, the charger uses an electrical component called a transformer. Transformers produce heat due to the normal process of conducting electricity. and also by eddy currents and other losses
In general, the more current a transformer provides, the more heat it will produce. Under normal circumstances, a phone charger can be a bit hot to the touchand that’s fine: it works as designed.
But if it’s more than hot, or suddenly unusually hot when it hasn’t been before, then you might have a problem. If the charger is so hot that it is uncomfortable to hold or touch, that is a clear sign that something is wrong.
This could be due to a malfunction within the charger itself, or a problem with the connection between the charger and the wall outlet. High-quality chargers have a protection circuit that automatically shuts down the charger if something goes wrong. There is a lot to know about it.
If the charger gets too hot, unplug it from the wall outlet and look for any visible signs of dirt or obstruction on the plugs that connect to the outlet. Also, check that the phone’s charging port is clean, and inspect the USB port.
Once the port is clean, try again, and if it keeps getting hot, try a different cable to see if the problem persists. Still, there are some cases where you don’t want to risk trying different cables, which we’ll cover below.
When does a USB charger become a fire hazard?
- Visible signs of melting in the plastic of the charger or the charging cable.
- An unusual odor coming from the charger, such as the smell of smoke or melted plastic.
- Burn marks (black or brown burn marks) on the charger, the cord, or the outlet to which the charger is connected.
- A sudden amount of heat that is new or unusual.
- Fraying, cracks, or physical damage to the cord or charger.
Remember that you should charge your phone away from anything flammable or combustible. This is valid for any charger, even for one that works well. Come on, on the nightstand or in the living room on a piece of furniture. Nothing to do on top of a magazine or near a blanket.
