Fast charging is a great smartphone feature that gives you the ability to charge your phone faster. In this blog post, I will explain what is fast charging and how it works.
What Is Fast Charging?
Fast charging is a term that’s used when referring to devices and chargers that are capable of charging faster than the standard 5-watt charger.
At the moment, there are various technologies that give us the ability to achieve fast charging, however, there is no industry-standard.
Due to the lack of an industry-standard, some manufacturers claim that their product offers fast charging but in reality, it only provides the standard 5W charging speeds.
This is terrible, I will tell you everything you need to know about fast charging.
Why Has Fast Charging Become So Popular?
Fast charging has become extremely popular within the past few years because it gives you the ability to charge your phone or tablet faster.
Fast charging is a convenient feature that gives you the ability to top-up your phone in significantly less time than it would take if you used the standard charging technology.
Due to the fact that there is no industry standard for fast charging all phones do not offer the same type of fast charging and all chargers do not support the different standards.
How Does Fast Charging Work?
The charge output is measured in amperage, voltage, and wattage. The Amperage is also referred to as the current which is the amount of electricity that flows from the battery to the device that it’s attached to.
The voltage is the speed at which the electric current moves. The wattage can be calculated by multiplying amperage by voltage, this is also known as the total power.
To achieve fast charging, manufacturers vary the voltage or boost the amperage which increases the amount of energy that’s going to a device.
However, the majority of fast charging standards alter the voltage instead of boosting the amperage.
The majority of phones and tablets are capable of managing 5V/2.4A. However, for fast charging, the voltage will be boosted to 5V, 9V, 12V, or higher or the amperage may be boosted to 3A or higher.
Smartphones are made in such a way that allows them to only take in as much power as their circuits are designed for.
So if you charge your phone with a more powerful adapter such as a 5V/3.1A, but it’s only capable of handling 5V/2A, this is the speed at which it will charge.
To use fast charging effectively, you must have a device with a charging circuit that’s compatible with one of the fast charging standards that are currently available and you must have a cable and an adapter that’s compatible with the same standard.
The Most Popular Types Of Fast Charging Offered:
Qualcomm Quick Charge:
Qualcomm Quick Charge is the most popular fast charging standard used today, this is due to the popularity of the Qualcomm Snapdragon processors that are used in many devices today.
There are different versions of Qualcomm Quick Charge available from V1 to V4 and every version is compatible with the previous version, this means that older adapters and cables will work with newer devices.
Quick Charge 4.0 makes it possible to charge devices with up to 28W of power.
Samsung Adaptive Fast Charging:
Samsung Adaptive Fast Charging is present on premium Samsung phones, this technology works in a similar manner to that of Qualcomm Quick Charge.
Samsung Adaptive Fast Charging achieves faster charging by boosting the amperage and voltage.
This technology is only compatible with premium Samsung phones that have compatible adapters that offer between 5V/2A (10W) for older phones and 10V/4.5A (45W) for newer phones and these adapters are also compatible with USB Power Delivery.
This technology makes it possible to charge phones such as the Samsung Galaxy Note 10 plus from 0 to 100% in a little under an hour.
OnePlus Dash Charging:
OnePlus Dash Charging is compatible with OnePlus phones, it boosts the amperage to 5V/4A which produces an output of 20W.
Huawei SuperCharge is very similar to the other fast charging technologies on this list because it works by altering the amperage and voltage.
This is done via compatible cables and adapters which gives you the ability to get an output of 5V/1A (5W) up to 4.5V/5A (22.5W).
Is Wireless Fast Charging A Great Alternative?
Wireless Fast Charging is very convenient but it may be slower if the wireless chargers do not have cooling systems or fans or if their charging speeds are 5V/1A.
However, there are a number of companies that offer fast wireless charging pads that have fans built-in to neutralize the heat.
This is great because it makes it possible for manufacturers to provide faster-charging speeds which are almost the same as the Fast Charging speeds offered when charging with a cable.
The amperage and the voltage vary depending on the charging pad. However, if you are looking for the ideal charging pad, you must make sure that your wireless charging pad and your phone support the same fast charging standard.
You will also need a wall adapter that plugs into the pad, this comes with the pad. However, if you lose it, you cannot replace it with any adapter and cable, the adapter and cable must be compatible.
Is Fast Charging Safe?
Due to the fact that fast charging technologies charge your phone at a faster rate than that of standard charging, your charger and your phone may heat up while charging.
If you are concerned about safety for best results, you should use high quality cables and adapters that support the same fast charging technology as your phone.
You should check the fast charging standard that your phone supports and make sure the adapter that you’re using supports the same standard (adapters are labeled) and make sure you use the cable that came with the adapter.
