Why can’t I see the universal charger now?

Remember the bunch of chargers with cables and charging heads in your home? At that time, each mobile phone had to be equipped with a dedicated charger. The charger was broken and only the same model could be bought. If the phone is broken, the charger is also abolished. The chargers between different mobile phone manufacturers are different. Even if the same manufacturer has different models of mobile phones, the chargers used are different.

This has brought business opportunities to some phone charger wholesale manufacturers. Later, there was a universal charger. No matter what mobile phone you have, it can charge you as long as the battery can be removed. The volume is not big, if you have a spare battery, one is used on the phone, and one is used to charge, it is very convenient. Why can’t I see the universal charger now?

Because it has a drawback, it starts with some of its shortcomings. Universal charger is not as good as the original charger. Just rely on a clip, if you loose it a little, you can’t charge it, and it’s easy to reverse the battery. Because the universal compatibility “compatibility” is too strong, it has many security risks. The battery capacity and circuit design of each mobile phone are different. The universal charger can’t make each battery just charge fully to stop charging. This leads to many batteries experiencing shortened life, bulging, and even explosion due to the use of universal charger.

The main reason for this situation is that there are no industry standards, so each country has issued different standards. The standard specifies that the mobile phone charger is separated from the charging cable and connected via a USB interface. This mobile phone charger can be universal, but the charging interface has not been unified yet.

The most important thing is that smartphones are basically built-in batteries and can’t be disassembled. So now charging treasure has become the mainstream.
