Fast GaN Charging vs. Traditional Chargers: Is Wireless Charging Faster?
Nowadays, charging has become an essential part of our daily life for various electronic devices such as smartphones, tablets or laptops. Therefore, keeping our electronic devices at full powered all the times and saying goodbye to low-battery anxiety is crucial for us so that we are able to keep up with the latest information on the Internet wherever we are, to greet and communicate with our friends and families, and to be able to call for help in case of emergencies in the outdoors. In recent years, wireless charging, a convenient and wireless charging method, has become more and more popular, and at the same time, what we concerned about is whether wireless charging is faster or slower than traditional wired charging.
With the increasing reliance on cell phones and other electronic devices have also led to a growing demand for fast and efficient charging solutions. To meet this demand, Gallium Nitride (GaN) materials have emerged as a promising solution. This article is aim to discuss the efficiency of Fast GaN Charging in the context of wireless charging speed.
II. Fast GaN Charging vs. Traditional Chargers
The difference between GaN charger and ordinary charger is mainly reflected in its circuit design and service life.
First, adopted GaN material as the circuit device, so GaN charger is lower in resistance value and better in thermal stability, so it can be more effective for power conversion and electrical energy storage. Secondly, due to the GaN charger generate less heat during use, so can extend the service life of itself. Thanks to the excellent semiconductor performance and high electron mobility of GaN materials, so that they can automatically switch between AC and DC power sources, effectively reducing the size and weight of chargers.
As a new type of charger, advantages of GaN charger are as follows:
- Fast charging: GaN charger has higher charging efficiency, which can fully charge cell phones or other devices in a short time without long waiting.
- Low-temperature charging: GaN chargers have a more stable charging process, and the temperature rises slower during charging, which helps to reduce the risk of temperature during the charging process, preventing damage to phone performance because of over-heating during charging, extending the lifespan of battery.
- Reduced size: GaN's main strengths in power electronics are high efficiency, low loss and high frequency, and owing to the rapid development of modern design ,it is compact design and lightweight.
- Environmental protection: GaN charger does not use harmful substances in the production process, the impact on the environment is smaller. Above all the mentioned, those are the reasons why GaN chargers shine in the charger industry.
In fact, many traditional chargers which most of them are made of semiconductor silicon material is too inconvenient to carry for its bigger size and it is a burden for you coupled with the bigger screen display phone. Compared to the past, if you try to use the same volume of large chargers, then it will cause consumer distress, and GaN charger is just the right solution to the pain point. However, GaN chargers are usually more expensive compared to regular chargers. Therefore, when choosing a charger, you can make a choice based on your real needs and usage environment.
III. Is Wireless Charging Faster?
When discussing the charging rates of wireless chargers, several variables can significantly impact your phone's charging speed. Factors such as the current battery level, active applications, screen status, and ambient temperature all play a crucial role.
Different smartphone manufacturers have developed various strategies to manage charging rates to safeguard the phone's battery life.
Here is a comparison of charging rates under optimal and less ideal conditions:
|Scenario||Best Case Scenario||Worst Case Scenario|
|Battery Level||Almost depleted (<5%)||Nearly full (>80%)|
|Applications||No active apps, especially GPS-intensive ones||Multiple apps running, including GPS-based apps (e.g., maps)|
|Temperature||Low (~20°C/68°F), in shade||High (30°C/86°F), in direct sunlight|
|Charge Rate||Increase of 1% every 2 minutes, or 30% increase per hour||Increase of 1% every 10 minutes, or 6% increase per hour|
100W wired vs 100W wireless charging test:
- Test performed using the iPhone 14pro smartphone
In the best-case scenario, with a nearly empty battery, no running apps, the screen turned off, and in a cooler environment, the observed charge rate is a 1% increase every 2 minutes, translating to a 30% increase in battery charge per hour.
Conversely, in the worst-case scenario with a nearly full battery, multiple applications running (including GPS-dependent ones), the screen on, and in hotter conditions (especially in direct sunlight), the charging efficiency can drop significantly, with only a 1% increase every 10 minutes, equating to about a 6% increase in battery level over an hour.
Let's keep the answer to this headline in suspense. Now please look at following two world-class experiments as follows via links and then draw accurate conclusions from them afterwards.
According to the above world-class experiments mentioned in the links, there is no doubt that wireless charging is slower that wired charging. And from the content of the link, the speed of charging power can depend on the distance between receiver and the transmission, the present battery capacity of the phone, whether the screen of the electronic device is lit up when charging or whether there are too many applications are running simultaneously and the ambient charging temperature. But the conventional chargers will reduce the power because of the heat generated while charging, leading lower power. Although classic cables won wired vs wireless charging race, it is recorded only a minute or two between key milestones and even a full charge. Fast wireless charging is virtually every bit as good as the best wired wall chargers, especially at high power levels. The real trade-off isn’t speed but heat, which, as we know, isn’t great for the longevity of internal smartphone components. But GaN chargers have large forbidden bandwidth, large critical breakdown electric field, high saturation electron drift speed, and stable chemical properties compared to traditional chargers made of traditional semiconductor silicon, which perfectly solves this problem.
