When we are still talking which new-released phone supports wireless charging, Huawei has jumped into the area of wireless charging other devices and spread the concept of reverse charging. So it means Huawei Mate 20 Pro can be used as a wireless charger, it sounds really cool right? Let’s check out how does it work and how fast Huawei Mate 20 Pro can wireless charge other devices?
What is Reverse Wireless Charging?
Unlike the traditional wireless charging in the iPhone or other Android flagship phones, Huawei Mate 20 Pro not only supports the 15W super fast wireless charging for recharging its 4200 mAh high-capacity battery, but also capable of applying ‘reverse charging’ to top up other smartphones wirelessly, the charging mat becomes the transmitter, and the setup on another phone becomes the receiver. It is really something ever developed, Huawei didn’t unveil the details about what kind of technology they applied, while this little gimmick draw a lot of customers’ attention.
How to use Huawei Mate 20 Pro to charge other devices wirelessly?
By opening up the settings, you can turn on Wireless Reverse Charging. Effectively you’re turning the Huawei Mate 20 Pro into a wireless charger for another device. What other devices are compatible, you may ask. All the Qi-enabled devices are working perfectly with Mate 20 Pro, you can use it to charge iPhone from iPhone 8, the same with a Pixel 3, Galaxy Note 9, or any other Qi-compatible device. How fast is the charging speed? According to the test result of most reviewers, the speed is relatively slow, technically slower than a conventional wireless charger.
Does Huawei Mate 20 support this function?
Not really, Huawei Mate 20 doesn’t feature this spec, probably the flagship giant wanted to differentiate the Mate 20 and Pro from this kind of small add-ons. Plus, Huawei Mate 20 Pro sports a 4200mAh gigantic battery, even if you share some power with a friend or charge your Qi-enabled earbuds, you should still have more than enough to get you through the day. This little trick might be your life-saver.
What if I place a Huawei Mate 20 Pro on the back of another Mate 20 Pro? Which one will be charged?
Well, it depends. Since you need to enter the setting of opening up the Reverse Wireless Charging function, if you only open one, apparently the activated one will charge the flat Huawei Mate 20 Pro. But there’s something interesting when you open up the function for both of them, no confirmed answer about which one will be charged yet. You may suggest the higher battery juice would charge the lower one, actually it may act in an opposite way, a Chinese influential YouTuber has already tried that and got the opposite result.
However, by adding this Reverse Wireless Charging function, it gets one more reason to buy a Huawei Mate 20 Pro other than iPhone XS Max. It might not be that sufficient to charge other devices in a short time, but it can be a good backup when you are on-the-go. Considering the other new features introduced by Mate 20 Pro, Huawei Mate 20 Pro is definitely one of the best smartphone in 2018.
