Reverse wireless charging, also known as wireless power sharing or reverse charging, is a feature that allows a smartphone to charge other devices wirelessly using its own battery power. This innovative technology has gained popularity in recent years, and many phone manufacturers have started to incorporate it into their devices. But which phones have reverse wireless charging?
The Concept Of Reverse Wireless Charging
Before we dive into the list of phones that support reverse wireless charging, let’s first understand how it works. Reverse wireless charging uses the same Qi wireless charging technology used to charge devices wirelessly, but in reverse. Instead of receiving power, the phone acts as a transmitter, sending electrical energy to other devices that support wireless charging.
This technology is based on the Qi wireless charging standard, which is widely adopted by many device manufacturers. The Qi standard defines a set of protocols and guidelines for wireless charging, ensuring that devices from different manufacturers can communicate and charge each other seamlessly.
How Reverse Wireless Charging Works
The process of reverse wireless charging is relatively simple:
- The phone with reverse wireless charging capabilities is placed face down on a flat surface.
- The device to be charged, such as a smartwatch or earbuds, is placed on the back of the phone.
- The phone’s wireless charging coil transmits electrical energy to the device.
- The device receives the energy and begins to charge its battery.
Phones With Reverse Wireless Charging
Now, let’s take a look at some of the phones that support reverse wireless charging:

Advantages Of Reverse Wireless Charging
So, what are the advantages of reverse wireless charging?
Convenience: Reverse wireless charging eliminates the need to carry multiple chargers and cables, making it a convenient feature for those who have multiple devices.
Emergency Charging: In situations where you don’t have access to a power outlet, reverse wireless charging can be a lifesaver, allowing you to charge your device on the go.
Sharing Power: Reverse wireless charging enables you to share power with friends or family members who may be in need of a charge.
Limitations Of Reverse Wireless Charging
While reverse wireless charging is a convenient feature, it’s not without its limitations:
Power Limitations: Reverse wireless charging typically has a lower power output than traditional wired charging, which means it may take longer to charge devices.
Compatibility Issues: Reverse wireless charging may not be compatible with all devices that support wireless charging, so it’s essential to check compatibility before attempting to charge a device.
Battery Life: Using reverse wireless charging can drain the battery life of your phone, so it’s essential to keep an eye on your phone’s battery level when using this feature.
Conclusion
Reverse wireless charging is a convenient and innovative feature that has the potential to change the way we charge our devices. While it’s not yet a standard feature in all phones, many manufacturers have started to incorporate it into their devices. If you’re in the market for a new phone, consider looking for one that supports reverse wireless charging. With its convenience, emergency charging capabilities, and ability to share power, reverse wireless charging is definitely a feature worth considering.
What Is Reverse Wireless Charging?
Reverse wireless charging is a feature in some smartphones that allows them to act as wireless charging pads, transmitting power to other devices that support Qi wireless charging. This innovative technology enables users to charge their accessories, such as smartwatches, headphones, or even other phones, without the need for cables or a separate charging pad.
Reverse wireless charging is also known as wireless power sharing or reverse charging. It works by converting the phone’s battery into a Qi-compliant wireless charging transmitter, allowing it to send power to other devices. This feature is particularly useful in emergency situations where you might need to charge a friend’s phone or another device on the go.
Which Phones Have Reverse Wireless Charging?
Several high-end smartphones from popular brands like Samsung, Huawei, and OnePlus have reverse wireless charging capabilities. The Samsung Galaxy S21 series, Galaxy Note 20 series, and Galaxy Z Flip are some examples of phones that support this feature. Huawei’s Mate 30 Pro, P30 Pro, and Mate 40 Pro also come with reverse wireless charging.
In addition to these brands, some OnePlus phones like the OnePlus 8 Pro and OnePlus 9 Pro also offer reverse wireless charging. However, it’s essential to note that not all phones from these brands support this feature, so it’s crucial to check the specifications of a particular model before making a purchase.
How Does Reverse Wireless Charging Work?
Reverse wireless charging works by using the phone’s internal charging coil as a transmitter to send power to other devices. The phone’s battery is converted into a Qi-compliant wireless charging transmitter, allowing it to transmit power to devices that support Qi wireless charging. When a compatible device is placed on the back of the phone, the phone recognizes it and begins transmitting power.
The power transmission process is usually initiated by enabling the reverse wireless charging feature in the phone’s settings. Once enabled, the phone will start transmitting power to the device placed on its back. The power transmission rate may vary depending on the phone and the device being charged, but it’s generally slower than traditional wired charging.
Is Reverse Wireless Charging Safe?
Reverse wireless charging is a safe technology that has been designed with safety features to prevent overheating, overcharging, and other potential risks. Phones that support reverse wireless charging are equipped with built-in safety mechanisms that monitor the power transmission process and adjust it accordingly to prevent any damage to the phone or the device being charged.
Additionally, reverse wireless charging operates at a relatively low power level, usually around 1-2 watts, which is much lower than traditional wired charging. This reduces the risk of overheating and ensures a safe charging experience. However, it’s still essential to follow the manufacturer’s guidelines and use the feature responsibly to avoid any potential risks.
How Long Does Reverse Wireless Charging Take?
The time it takes to charge a device using reverse wireless charging depends on several factors, including the phone’s battery capacity, the power transmission rate, and the device being charged. Generally, reverse wireless charging is slower than traditional wired charging, and it may take several hours to fully charge a device.
For example, if you’re using a Samsung Galaxy S21 to charge a Samsung Galaxy Watch, it may take around 2-3 hours to fully charge the watch from 0 to 100%. However, the actual charging time may vary depending on the specific devices and their capacities.
Can I Use Reverse Wireless Charging To Charge My Laptop?
Reverse wireless charging is primarily designed for charging small devices like smartwatches, headphones, or other phones. It’s not suitable for charging larger devices like laptops, which require much higher power levels. Most phones that support reverse wireless charging have a limited power transmission capacity, usually around 1-2 watts, which is not enough to charge a laptop.
Laptops require higher power levels, typically around 20-60 watts, to charge efficiently. Using a phone’s reverse wireless charging feature to charge a laptop would be extremely slow and inefficient, if not impossible. If you need to charge your laptop on the go, it’s better to use a portable power bank or a dedicated laptop charger.
Do I Need A Special Case Or Accessory To Use Reverse Wireless Charging?
You don’t necessarily need a special case or accessory to use reverse wireless charging. If your phone supports this feature, you can simply enable it in the settings and place a compatible device on the back of the phone to start charging. However, some phones may require a special wireless charging cover or case to enable reverse wireless charging.
In some cases, you might need a specialized wireless charging pad or dock that supports reverse wireless charging. These accessories can enhance the charging experience and provide a more convenient way to charge your devices. However, they are not essential for using the feature, and you can still use reverse wireless charging without them.
