When would you replace your old phone charger from your mobile accessories? Here goes a listing for you. If your phone charger is not original phone charger when you buy the phone, try to check. Replace your phone charger as soon as possible once your phone charger is like below. 

Phone Charger with Loose Connector

It is very dangerous to have a phone charger with loose connector. it is easy to get broken and make the connector metal part contact the user and get electrical shock.

If above did not happen, there would be a risk of fire because of the high resistance between the power socket and the phone charger.  As the time goes on, the phone charger pin plugs will get hotter and hotter and finally result to fire.

Ampere Doesn't Match with your Phone

Some old phone chargers are with 5V 1A output. But latest phones are with smart quick chargers. The mobile phone still get charging but very slow. 

But this will make the charger in full output anyway.  The old phone chargers are designed to work with old phones with 1500-2500mah batteries while the new smart phones reach 5000mah or more batteries. This will make the phone charger work twice, tripple or more time without a stop. It will damage the phone charger very fast. 

And the phone will remind the battery ICs that it is still in charge. Things like, a man who is very hungry want to eat to full very quickly. But the food comes very slow and tiny to him. He has to take the tiny food while hungry. 

It is very important the Ampere (output currency) matches with the min requirement of the mobile phone to keep the phone in a good charge condition. 

Phone Charger Rusty

Some phone chargers are rusty. The pin plugs are rusty because of wet. And some even worse, the inside components are wet too. And some USB charger Port may get rusty. 

It is dangerous to have that charger. This will lead to electrical shock to the user or explosion for the charger. 

Phone Charger with Physical Distortion

We can see this problem from the phone charger lookings. If it is a light hurt only to the phone charger housing, we can use that charger as usual. 

But, if the mobile phone charger is damaged for some reason that you do not know, or housing broke, or drop with a heavy hit to the gound … we suggest you to get another one instead. If the components inside gets off, the phone charger will not work any more. The serious problem is, this may lead to a electrical shock to the user or smart phone damage.

Poor workmanship or defective materials

We see some smart phone chargers are with very good lookings. But it will give you some strange feelings when you know some information – the prices is very low, it is very light or other. 

We opened the chargers and found poor workmanship of the PCB and defective materials used. It is very easy to make the phone battery dead after several charges to the phone. 

No protection ICs inside the PCB – this is the main reason for the bad phone chargers. To save the costs,  the travel charger manufacturer use as less components as he can to reduce the costs. 

Frankly speaking, these travel chargers are looking good and will not cause problems at beginning. They will damage the batteries little by little till you replace the phone charger or your smart phone batteries.

What a good charger will bring you?

When you are buying a travel charger, car charger or even a wireless power bank charger, you will doubt the quality if the band name is not good enough for you to recognize. What is a good charger for your phone? Let us make things simple and check as below:

  1. Input Protection: No matter the travel charger or the car charger, this is a must for it. It is for safety purpose. It will avoid electronic shock from AC or getting fire by transfer the 90-240V AC or 12/24V DC to the right voltage to your phone.
  2. Output protection: This is a bit complicated. No matter the travel charger or the car charger, it should provide the right voltage and currency for the phone to charge. If no protection for output, the charger will still keep charging the phone! As the worst result, the phone cannot stop the charge and it will cause fire or smoke just by continuous charge!Things would be different if the charger or phone has a protection!
  3. Stable Currency: The charge will put more currency when it begins to charge the phone, less in the middle and 0 at the end. Why I say stable here? It will always keep the same? Of course no! The stable currency means that, it will meet the charging currency for the phone needs. For example, at the beginning the phone requires 1.8A and 5V, which is the right currency that phone needs to put its max charge. Suddenly the currency goes to 2.5A or more. It would be bad for the batteries even it does not cause explode or fire.
  4. Stable voltage: the same importance as the stable currency.
  5. With fuse: Of course the IC cannot protect your phone fully when lightning in a stormy day. But a fuse can burn and protect your phone when there goes a 10X input currency or voltage.
  6. Burning protection: A good charger will select good plastic materials which will help you when the charge has a problem itself. It will protect your charger itself from burning. The worst is that it will cause smoke and will not get fire.
  7. Life time: A good charger can last 5 years or more without any problem. A cheep one may remain only 3 months. And the good one can make your phone work well. A bad cheep charger may lead your phone to a short life.

A Good Mobile Phone Charger With a Good Use Habit

As a professional mobile phone chargers supplier in the past decade, I would NOT be surprised that chargers get fire or explosion when charging a phone, even phone explosion, destroy the room, the worst, to cause death of people. Are you serious? You may ask. I am not going to joke on this. It is true.

Mrs. Sun was waked up because there is a pop explosion at mid night. She tried to turn on the light in the bedroom to check what happened but could not get a success. Then she thought that the flashlight of the mobile phone could be of help. She was amazed to touch a hot mobile with damaged phone screen. Till this moment, she realized that she got a problem with her phone.

“I am still lucky.” She said, “If I put the phone near my bed, I would get scratches on my face by the glasses from screen and not the phone! The phone was being charged on a desk which is a bit far from my bed.”

Mrs. Sun checked everything later and found that it was the charger who gives a pop explosion. The charging cable was blown out. The metal part inside the mobile phone charger was burned to be black.

Nothing was lost except the phone and the charger in this story. You know, many potential problems will lead to this explosion. My explanations are as below:

  1. Original mobile phone chargers are subjected to wet or humid charger, long time standby or longer use life for explosion. As we know, original mobile phone chargers are the quality standard. It is easy to us to understand why a wet or humid charger will cause problems or electric shock. Long time standby without charge to phone will cause the components inside the charger to be weak and weaker. Long time standby time will reduce the mobile phone charger life. Longer use life will cause problem too. Normally we should replace the mobile phone charger every two years.
  2. Chargers are without protection. A good IC is the safe gate for mobile phone chargers. Some mobile phone accessories buyers or dealers care the prices much more than the quality they purchase. They buy chargers without full protection or even without protection. Good protections cover-
    -High input voltage protection;
    -High output voltage protection;
    -Over currency protection;
    -High temperature protection;
    -Short circuit protection;
    -Anti-fire housing material.
  3. High copy or none professional designed chargers. You know what I am saying now. I am with this industry for more than 10 years and there are some mobile phone chargers factories employ some none professional engineers. The engineers are not professional enough to design a PCB with customized costs. This will lead to problems when the users start to charge mobile phones.
  4. Some mobile phone chargers manufacturers are keen to copy the original mobile phone chargers designs and housings and name them HIGHT COPY chargers. It means that the charger housing and the PCB are the same as original phone charger. I doubt the quality of the high copy ones. How can they get the same components as original mobile phone charger? Even they can get the same band as originals how can they guarantee the same procedure? Even they are sure of everything same, how come to the big difference of price? The same components, same procedure for production, same testing and QC, everything is the same. Of course, it is the same sales price. There should not be so much difference if not the same sales price.
  5. Charge mobile phones in a hot place. A phone charger will heat when charging a mobile phone. If the place is hot, it will zoom the risk of fire or other problem.
  6. Charge mobile phones when the phone in use. This is a very bad habit when charging. As we know, strong currencies will pass the mobile phone PCB from the battery to keep the call on. The charger will also push strong currency to get the phone battery charged.

A mobile phone charger is to transform 110V, 220V or other high voltage to 5V or other low voltages.So, what shall we do for a mobile phone charger?
