Science and technology development speed

Quick charging is an increasingly popular function that allows you to only need a small part of the time to complete the work of charging mobile phones.

But not all the calls use the same type of fast charging-not all chargers support various standards.

Understand fast charging

The output of the charge is measured by ampere digital and voltage.

The current is the power from the battery flow to the connection device, while the voltage is the strength of the current.

The voltage can be multiplied by the current, that is, the total power measurement.

In order to make the equipment charging faster, most manufacturers either increase the number of ampels or change the voltage to increase the potential energy of entering the device. Most fast charging standards will dynamically change the voltage instead of increasing ampel.

The output level of the standard USB3.0 port is 5V/1A, which is suitable for small devices such as wearable devices. Most mobile phones and other devices can handle 5V/2.4A. For fast charging, you are looking for an increase in voltage to 5V, 9V, 12V, or higher voltage, or increase the current to 3A or higher.(Lithium - Ion Battery Equipment)

Remember, your phone can only receive the power of the charging circuit.

So even if you connect it to a 5V/3A adapter, if it can only process a voltage of 5V/2.4A, the charging speed is the same. To make fast charging, you need to have a mobile phone or other devices with charging circuits in order to use one of the fast charging standards and enable adapters and cables for the same standard.

Fast charging type

Due to the universal nature of the company's chipset, the most common fast charging standard is Qualcomm's fast charging. Fast charging 2.0 and 3.0 are the two fast charging types you are most likely to see now, and fast charging 4+ will be launched soon. Each standard is compatible with the previous standards, so the older cables and adapters can still work.

Quickly charging 2.0 with a high interval between 5V, 9V and 5V QuickCharg3.0 can increase the voltage in a wider range. The dynamic range ranges from 3.2V to 20V, although the peak power of these two standards is 18W. This means that LGG6 and other mobile phones can reach 80 % of the charging in just 35 minutes.

Quick charging 4+ reduces the voltage range when improving the number of ampels. You can get 5V voltage between 4.7A and 5.6A, or get 9V voltage at 3A. The QuickCharge4+device uses the USB-C port, and is in line with USB power supply (see the "transcendence of your mobile phone" section below).

They also have the second power management chip, which can provide up to 28W power without heat. We have not tested any fast charging 4+ mobile phones, but theoretically it allows them to charge them from zero to 50 % within 15 minutes.

Samsung adaptive fast charging

Samsung's adaptability is not as common as in the past, but works similar to the above standards by increasing voltage and/or ampere digital. As you may imagine
