What is fast charging?

Virtually every new smartphone launched promises faster charging speeds. But what do the different fast charging standards mean, and are their speeds the same? This article of us will give you the answer.

When your smartphone or tablet has fast charging, the time you have to wait for the device to fully charge will be shorter. Fast charging is becoming more and more popular and it helps you to recharge your device in less time compared to old technology. But not all devices share the same fast charger and not all chargers support different charging technologies. Here's what you need to know to make sure your device is charged as quickly as possible.

What is fast charging?

The output of the charger is measured in terms of amperage and voltage. Current symbol A is the amount of electricity flowing from the battery to the device to be charged in a period of 1 second. Meanwhile, the symbol voltage V is a unit of measure the potential difference between two points of a conductor when there is a current with a magnitude of Amperes running through and for a capacity of Watt (W). Multiply V by A you get watt (W) charging capacity.

What is fast charging? Rapid charge technology shortens the time it takes to fully charge electronic devices

To charge a device faster, manufacturers can increase A or V to increase W. However, most current fast charging standards choose to increase the voltage V over the increase in current A .

A standard USB 3.0 port can provide 5V / 1A power to small, wearable devices like smartwatches. Most smartphones and other devices are capable of receiving 5V / 2.4A charging capacity. To charge faster, you must look for chargers that support 5V, 9V, 12V or higher or 3A or higher.

You need to remember that your smartphone receives only the correct amount of power by the numbers for which its charging circuit is designed. Therefore, for fast charging to work you need both a charger, a smartphone and a charging cable that supports fast charging.

Current fast charging standards

Fast charging Apple

From iPhone 8 onwards Apple has equipped with fast charging for all iPhone models. However, except for iPhone 11 and 11 Pro Max, other iPhone models are only equipped with 5W charger by Apple.

What is fast charging? From iPhone 8 onwards, Apple's iPhone models support 18W fast charging

To quickly charge iPhone from iPhone 8 onwards, you need a charger with a minimum capacity of 18W with a USC-C to Lightning cable. With this, you can fully charge 50% of the iPhone's battery in just 30 minutes. The higher capacity charger doesn't harm your iPhone, but it doesn't help either.

MediaTek's Pump Express Quick Charge

Some of MediaTek's smartphones use Pump Express fast charging technology. Here are the parameters of Pump Express

  • Pump Express 2.0+: Voltage from 5V to 20V, amperage from 3A or 4.5A,
  • Pump Express 3.0 and 4.0: amperage 5A.

Rapid Charging and Rapid Charging by Motorola

Motorola smartphones use two different fast charging technologies. Normally, low-cost smartphones such as the Moto E and Moto G series will use Rapid Charging with a capacity of 10W. Meanwhile, high-end smartphones will use TurboPower with a capacity of 15W and 18W.

Quick Charge on OnePlus Dash Charge and Warp Charge

In fact, OnePlus buys a license to use Dash Charge and Warp Charge from Oppo. Similar to Oppo's VOOC fast charging technology, Dash Charge and Warp Charge raise voltage and power to 5V / 4A to reach 20W. On smartphones like the OnePlus 5T, you can charge 60% of the battery in just 30 minutes.

What is fast charging? OnePlus has Dash Charge and Warp Charge fast charging technology

New smartphones like the OnePlus 8 Pro support fast wireless and 30W wired fast charging thanks to Warp Charge technology. Warp Charge wired fast charger will use the 5V / 6A charger and USB-C cable respectively. However, to achieve 30W of power for Warp Charge wireless charging, OnePlus had to use a 20V / 1.5A charger.

Fast Charger SuperVooc Flash Charge by Oppo

Vooc is Oppo's exclusive fast charging technology. For many years, Oppo has always been the leader in fast charging technology and currently holds the record for fastest charging in the world with a 65W charger, able to fully charge Reno Ace smartphones in just 31 minutes. Furthermore, Oppo is the only major smartphone company to use gallium nitride (GaN) batteries to increase smartphone performance and reliability.

Quick Charge by Qualcomm

Quick Charge is the most popular fast charging technology because Qualcomm's chips are widely used in the market. Currently, Quick Charge has the 5th version with the ability to support charging technology with a capacity of up to 100W.

Adaptive Fast Charging by Samsung

Below is a table of fast charging specifications for Samsung smartphones:

What is fast wireless charging?

Wireless charging is convenient, but often slow. Most wireless chargers usually do not come with fans or cooling systems, so they only limit the output to 5V / 1A. Currently, many companies have upgraded their wireless charging plates with built-in fans to increase charging speeds to almost on par with wired charging.

What is fast charging? Current wireless charging can also charge fast

Just like wired charging, for fast wireless charging, you need to buy a charging dock, charger, cable that matches the fast charging capacity of your smartphone.

Fast charging on laptops and other devices

Fast charging technology is not very popular on laptops due to the low demand for fast charging. Of course, faster charging is always better, so there are now a number of companies that offer fast charging capabilities for laptops. Scientists are also looking to develop ultra-fast charging technologies to meet electric equipment and vehicles such as cars, airplanes ...

What do you need for a quick charge?

With that said, you need to find out which fast charging technology your device supports, what is the maximum capacity. Next, you need to know whether the charger and cable that comes with you when you buy the device support maximum fast charging capacity. If not, you need to equip the charger and corresponding charging cable to get the best out of the fast charging technology your smartphone supports.
