The difference between regular and fast charging in cables and adapters

The difference between regular and fast charging in cables and adapters Fast charging – a feature of today's phones that users of modern gadgets have already gotten used to.
It truly enhances and simplifies its use at times when there is no opportunity to keep the device near a power outlet for long.
Many are curious to understand how the fast charging system is arranged in all its elements.

Fast charging in the adapter

 At first glance, it can be noticed that the power block that facilitates fast charging is significantly larger than the usual one.
However, their main difference lies in the current strength (the highest to date - 5.7A). The voltage and maximum power also differ.
While in regular chargers these measures are up to 5V, up to 5W respectively, in updated (improved) devices, these voltages reach up to 20V, with the next indicator reaching 30W.
The time for a full charge of the phone with such a device takes from 30 minutes, whereas a few years ago, powering the device took at least 5 hours.
Undoubtedly, the charging speed is influenced by the quality of the voltage in the electrical network to which the adapter is connected. If this indicator is below the norm (less than 220 volts), the time for a full charge of the device increases.

The most popular manufacturers of fast charging adapters, their characteristics
Apple (14.5V; 2A; 29W).
Among the advantages: fast, dynamic development (with each update, the quality of the device's operation noticeably improves).
Suitable only for brand products, compatible only with Lightning-USB-C type cables. Qualcomm Quick Charge (3.6V-20V; 2A-4A; 10W-27W).
The company has developed 4 generations of adapters, each with improved characteristics compared to the previous one. Among the features: battery protection, and other components dependent on electricity.

Samsung Adaptive Fast Charging (5V-9V; 2A; 18W).
Experts claim that this model is the safest among fast chargers for the phone battery (it does not have the property of heating up significantly).

Motorola TurboPower (Lenovo) (5V-12V; 1.2-5.7A; 15W-28.5W). Mediatek Pump Express (3V-20V; 3A-5A; 5W-30W).
One of the safest technologies that protect the phone from overheating. The downside: in most cases, it is only compatible with devices that contain a MediaTek chipset.

OnePlus, Oppo Vooc (5V; 4A-5A; 20W-25W).
Perhaps the record holders among all existing fast device adapters in terms of charging time. Among the downsides: only original cables from the kit are suitable, compatible only with Vooc, Dash Charge batteries. Huawei SuperCharge (4.5V-5V; 4.5A-5A; 25W).

Cable that supports fast charging technology

The key difference between a regular cord and a fast charging cable is its strength (measured by the amount of energy it can transfer from the adapter to the gadget).
Regular ones can transport no more than 2.5 Watts, while improved, fast ones can transfer up to 120 Watts.
A visual difference is also present: a fast charging cable is noticeably thicker than a regular one, although thickness is not always an indicator of shorter charging time.
It is important to pay attention to the characteristics indicated by the manufacturer on the packaging.
The length of the cord also affects the charging time of the phone (the longer it is, the longer the charging time).
This is due to the high resistance in long cables, which in turn "supplies" less current to the phone battery.
To ensure truly fast charging of the phone, it is necessary to properly select the adapter and cord.
If there is a very powerful block, but the cable is regular, the charging time will not be accelerated, as not all the current from the adapter will reach the battery, but only what can "pass" through the cord.
