Many modern gadgets can be charged at an accelerated pace, which can significantly increase the mobility of such devices. This article will talk about Quick Charge 3.0 technology, which is used in Qualcomm Technogies chargers.

What is Quick Charge 3.0
Quick Charge 3.0 is a mobile device charging technology by supplying a larger value of current to the battery contacts. You can use fast charging only if your smartphone or tablet supports this function.
Thanks to the built-in controller, the product allows you to automatically select the optimal voltage value, which allows you to use one device to charge several gadgets.
How Quick Charge 3.0 Technology Works
The main advantage of Quick Charge 3.0 technology is the optimization of power supply to the battery of a mobile device from the moment it is connected. Thanks to the inclusion of an increased charge level, it is possible to replenish the energy supply by 50% in a very short time. If it is possible to charge the device for an hour, then the battery capacity will be restored completely.
Despite the fact that the battery is charged with high current, this process is carried out according to a certain algorithm in order to minimize the negative impact on the battery of the gadget.
Advantages and disadvantages of charging QC 3.0
Unfortunately, the charger of this model is not without drawbacks. Among the most noticeable disadvantages of Quick Charge 3.0 devices are the following:
- Not all models of phones, tablets, power bank and other types of equipment support this function.
- As a rule, there is no cable in the charger kit.
- Higher price.
- The presence on the market of a large number of fakes.
Almost all of these shortcomings are easily fixed or you can not pay attention to them at all. A USB cable can be purchased at almost any electronics store, and if at the time of purchase you ask the seller for a quality certificate and documents for the goods, then the risk of acquiring a counterfeit product will be minimal.
The positive qualities of Quick Charge 3.0 chargers include:
- The increase in charge speed, compared with conventional devices, more than 4 times.
- High quality.
- Universality.
The main advantage of such devices is the speed of charge recovery. This basic quality is decisive for many owners of modern gadgets when choosing a new memory for a phone, laptop or tablet.
Than Quick Charge 3.0 Surpasses 2.0
Almost all modern technologies do not stand still, but are developing dynamically. This rule also applies to Quick Charge standards. QC 2.0 charging technology appeared in 2015, but almost immediately became very popular with owners of various gadgets.
The advantage of this method of transferring current from the memory to a portable device was the ability to increase the voltage to 9, 12 or 20 volts. This parameter directly depended on the type of battery of the charging device. Charging in the automatic mode is adjusted to a specific model of phone, laptop or tablet, providing the ability to charge the gadget in a very short time.
The QC 3.0 standard was released a year later. This technology far outperformed Quick Charge 2.0 in many ways. First of all, the changes affected the following parameters:
- Charge voltage.
- Charging speed.
Now it is possible to charge mobile devices running on batteries, the voltage of which is from 3.6 to 20 Volts, while the value of this parameter was set in increments of only 0.2 V.
In this version, chargers come in two classes:
- Class A.
- Class "B".
Class “A” includes memory devices whose maximum voltage does not exceed 12 volts. Class “B” corresponds to devices that can charge gadgets with 20 V batteries.
High rates of charging of mobile devices are due to a significant increase in amperage compared to original chargers. In Quick Charge 3.0 charges, such a change in parameters is very smooth, which avoids overheating of the conductors.
Which devices support Quick Charge 3.0
Unfortunately, not all models of mobile gadgets support this charging standard. To abandon the compatibility with this technology of many electronics manufacturers is prompted by the negative impact of this method of charge recovery on battery life.
When recharging, such batteries can become very hot, swollen, and even explode, which can result in personal injury or fire. Despite the fact that the charging process is regulated by a special controller that will turn off the product when certain battery indicators are reached, the negative consequences of applying an increased current strength will still occur over time.
Using Quick Charge 3.0 technology with Type C cables is also a concern for many electronics manufacturers. As time has shown, often the cause of the failure of the gadget became cables of this design. For this reason, it is not recommended to connect the charging of this class to Android-devices.
You can use fast charging technology only if your phone or gadget supports this function. You can find out about the availability of this feature from the instructions for the device or on the official website of the electronics manufacturer.
