Why cheap cables can kill your cell phone when charging


Charge, it does not charge, it does it slowly or it shuts off very quickly after having it plugged in for a long time. These are some signs that something is wrong.

The next time you decide to connect your cell phone to a charger, you may have to ask yourself: is this a poor or poor quality cable?

The question is not simple pedantry; A cheap charger could cause irreparable damage to your phone .

The situation is familiar to many. You run out of battery and grab the first charger that is put within reach to give a couple of lines to the battery of your cell phone. Saved.

Or you can buy an extra charger, at a reasonable price, to have in the office or take with you everywhere.

However, depending on the cable in question, this is not a recommended practice at all.

These are some of the effects they may have:

1. Fry your cell phone

The cable of your cell phone is actually a current transformer that converts the voltages of a circuit into those your phone needs.

This is done thanks to a chip, which in iPhone phones is called Tristar but generically called E75 or U2 and which regulates the amount of energy that your phone’s board can receive.

As Jesa Jones, of the specialized Ipad Rehab blog , points out, the E75 scans and makes sure everything is fine before the current starts to pass. If a cable does not have the necessary chip then a message will appear on your cell indicating that the accessory is not compatible.

So why does not this appear on your device when you connect it to a cheap cable?

The answer is that many companies manufacture a fake E75 that tricks your cell phone to let the current pass but could end up with your phone if you connect it to a high voltage current.

2. Slower loads

A cable that does not know how to regulate the volts of the circuit will also make the loads more irregular , with highs and lows. Without a constant energy fluctuation, the full charge will be much slower than with the cables that control the supply.

3. Security problems

Many times cheaper cables, so as not to shoot up in costs, save in isolation.

Leaving hundreds of volts of electricity through a cable without proper control can melt your charger and also the plug to which you have it connected.

Usually the electricity panels of the houses jump when this happens and does not have major consequences but you can take a scare and end with a plug and charger ruined.

How to find a good charger

It is not always necessary to pay the prices imposed by mobile phone manufacturers, as they are usually higher, but it is advisable that you try to find one that has a manufacturing guarantee that ensures that they were designed for that specific model.

In the case of the iPhone many accessories that are not Apple but manufactured for signature products such as headphones, chargers, etc … they carry a sticker that says MFi, which means Made for Phone (made for iPhone).

But if you still doubt that they can cheat you with imitations, these are some signs that your charger is not the right one , says the expert in repair of electronic devices Matthew Zieminski in an article on the portal Medium :

  • Not loading.
  • False load (shows the battery icon but the percentage is at 0%).
  • The battery drops from one percentage to another quickly.
  • The load is random: sometimes, very fast; others, very slow and others stagnate.
  • The battery is at a certain percentage, far from 5%, and it shuts off suddenly.
