Need to know what is reverse wireless charging? Then, you have come to the right page. Reverse wireless charging, also known as “backward charging” or “reverse charging”, is a technology that allows electronic devices to charge by being placed on a charging mat or another surface. The technology was developed to allow users to charge their devices without plugging them in and is especially useful for charging devices that are not easily accessible. Please keep reading for more details!
What Is Reverse Wireless Charging?
A new low-power solution that enables reverse wireless charging is now available. This innovative technology makes it possible to charge devices wirelessly by simply placing them in close proximity to a power source.
This could be a great solution for those who need to charge their devices frequently, but don’t have access to an outlet.
It allows you to wirelessly charge your phone using a different charger than if you used a particular charger. It transfers energy to the receiving device via electromagnetic induction. It works like this: one device charges the other, and one phone acts as the charging pad (charging station)
Although it sounds fantastic to turn your phone can actually charge wirelessly other devices support reverse wireless charging that has been controversial.
Charge your wireless accessories
Wireless reverse charging can charge Qi-enabled accessories such as smartwatches, wireless headphones, Apple AirPods, Galaxy buds electric toothbrushes and other device. This is a great way to quickly charge your daily accessories, as they only consume a very small amount of energy.
Quick Battery Boost for You or Your Friend
Although reverse wireless chargers cannot provide a significant boost in charging a smartphone, it can be used for making calls or returning home safely.
Although most smartphone users use a power bank to charge their devices during the day, it is still difficult for many to remember to set the power bank or bring a cable. This is possible in cases where you’re not prepared.
The Samsung Galaxy Series are good example of devices support reverse wireless charging. Wireless Powershare can charge any Qi-enabled smartphone including iPhone 11.
It has one major drawback: it charges much faster than other types of charging. Juan Bagnell, a YouTuber, found that the Samsung S10 could only increase the charge of an LG V40 by 8% in 30 minutes. This is in contrast to charging your own battery using a wall outlet that can charge up to 50% of the time.
You can only use reverse wireless charging if there is no other option or you urgently need it.
It is inefficient
Every 2% you add to a device’s battery, 5% is lost. This results in an electrical transfer loss rate of 60%. This charging generates heat, so the device must be used as a power bank. It takes about an hour to charge 10% of the battery.
Overheating and other factors can lead to a faster battery death.
Most wireless chargers generate more heat than wired charging, which is why it raises the phone’s temperature so much. You should only use reverse wireless charging for an essential purpose. Otherwise, you could damage your phone’s battery.
It’s also inconvenient
It is also challenging to reverse wireless charges. One phone must be placed face-down on a flat surface to keep the devices connected. This prevents the user from accessing the phone charging and the device it is charging.
Reverse wireless charging of a phone with a charge rate of up to 10% can take longer than 30 minutes. This can be frustrating for even the most patient users. The risk of scratching a phone’s screen by placing it face down increases.
What Is The Speed Of Reverse Wireless Charging?
This technology is slower than wired. This low-power option is best used for emergencies, such as when a friend loses a cord and is in danger of losing 5%. You can also use this to charge your wireless charging headphones.
We expect more, with 125W in the future. This is a full charge that takes less than 30 minutes.
Although Qi wireless charging may not be as fast, it is improving. The OnePlus 9 Pro is one of the 50W-wireless charging capable phone. This is about a third to half of the fastest wired equivalent.
There is no standard for reverse wireless charging, and no manufacturer has published the specifications. It is slower than normal, with a maximum of 10W. It’s perfect for topping up at the bottom end of your own battery cycle.
How Does Reverse Wireless Charging Work?
This is a relatively new wireless technology and is only available in select smartphones. It uses the same technology standard wireless charging to transform your phone into an electric power bank.
It cannot be easy to align two devices. However, phones with reverse wireless charging allow users to place any Qi wireless device directly on the wireless charging pad. Once the device is in place, it will start charging.
What Phones Can Be Charged Using Reverse Wireless Charging?
You will need devices support wireless charging to charge other devices. Many brands offer such devices. Make sure to check the specifications to verify the presence of the reverse wireless charging feature.
A receiving device does not need to be capable of reverse wireless charging – as long as it is Qi wireless charging compatible, it will be able wirelessly to charge.
These are the Android phones that support reverse wireless charging.
- Huawei Mate 30 Pro
- Huawei Mate 20 Pro
- Samsung Galaxy M31s
- Samsung Galaxy S10
- Vivo U20
- Xiaomi Redmi Note 9
Reverse Wireless Charging VS. Wireless Charging
Qi wireless charging is the most widely-used wireless charging standard. There are many other standards. You can place your smartphone on a charging plate and it will drain the energy and store it in its battery.
It’s not wireless charging, but it is a misleading term. Wireless charging is not the same as “wireless”, which refers to data transfer over the air.
Wireless charging is named because it doesn’t require you to plug in a cable to charge your phone. Instead, you can place the pad on top of it. The only way to charge your phone is to contact the charging pad physically.
Wireless charging is still convenient for devices such as smartphones and AirPods.
Is Wireless Reverse Charging Useful?
It all depends on how you view it. Many technological problems currently plague reverse wireless charger. Reverse wireless charging is slow. It can only charge at 10W. This is slower than Qi charging pads which can charge anywhere from 30W up to 80W.
You shouldn’t expect to be able to charge another smartphone or earbuds within minutes using reverse wireless charging phones.
This type of charging can also drain your smartphone’s battery because it sends its juice to the device receiving reverse wireless charging. Due to the laws of energy transfer, some energy is lost as heat.
It is possible to manage heat loss, but reverse wireless charging doesn’t do well. If your smartphone is at 50% battery power, and reverse wireless charging sends half the energy to other devices, your smartphone didn’t lose 25%. This is because half of the power could be lost during heat transfer.
This charging can only be used for emergencies if your other devices require 5% to 10% more battery to last a critical time.
If your reverse wireless charging compatible smartphone is plugged directly into a power source, it doesn’t matter what the heatless means. Your phone will be charging from the plug.
