Huawei Mate 30 reverse wireless charging review, can charge Qi protocol devices

In 2018, Huawei applied the "reverse wireless charging" function to Mate 20 Pro mobile phones for the first time, which is a functional innovation. My friend ’s mobile phone (requires wireless charging) is dead, it ’s enough to relieve the need; or my sports bracelet or TWS ’s Bluetooth headset (requires wireless charging) is dead. Can be "resurrected" and then used.

On the latest flagship Mate 30 in 2019, Huawei continues this feature. Let's take a look at the actual performance of Huawei Mate 30's "wireless reverse charging technology".

Use a wireless charger tester to test the voltage and current of the Huawei Mate 30 wireless output. The measured results are: voltage 5.33V, current 0.95A, power 5.06W, and transmission frequency 132.2kHz.

We have also tested the wireless charging of Huawei Mate 20 Pro before. The reverse wireless charging output power of Mate20 Pro is about 3W and the frequency is 112.1kHz. In terms of power, Mate30 reverse wireless charging power has been improved compared to Mate20 Pro.

How about the actual charge? How much can I charge my phone in half an hour? I took an iPhone 11 Pro for testing, and another phone turned on the countdown function and set it for 30 minutes.

The battery capacity of Huawei Mate 30 is 4200mAh, and the battery capacity of iPhone 11 Pro is 3190mAh.

The battery capacity of Huawei Mate 30 is 4200mAh, and the battery capacity of iPhone 11 Pro is 3190mAh.

The current iPhone 11 Pro's battery is 0% (the phone automatically turns off). It is placed behind the Huawei Mate 30. The wireless charging function is turned on immediately, the screen is lit (as shown in the figure), and charging starts.

After 30 minutes, the remaining power of Huawei Mate 30 is 88%, consuming 12% of power, and the iPhone XS is charged to 9%.

So how much can it charge in the whole process? Xiao Bian fully charged the Huawei Mate 30 and discharged the iPhone XS to automatically shut down. The Mate 30 reverse-charged the iPhone XS test. This test took 2 hours and 49 minutes, and the power of the Mate 30 went from 100% to 20%. iPhone 11 Pro charged from 0% to 47%. In the end, Huawei Mate 30 has 100% -20% battery power and iPhone 11 Pro has 0% -47% battery power.

Why not charge the iPhone 11 Pro with 100% of the power of the Huawei Mate 30? Because the Huawei Mate 30 has set its own power below 20%, the system will turn off the reverse charging function to avoid providing battery life for others but it will not be able to use it when it is turned off.

With the test shows that Huawei Mate 30 has good support for mobile phones and headsets that support the "Qi" protocol wireless charging, while private protocol products such as the original Apple Watch will not be able to charge it.

Summary of charging head network:

Huawei once again applied the "reverse wireless charging" function to mobile phones. In actual tests, the output power is about 5W. It is no problem to charge some small devices, such as sports bracelets and TWS headsets. The speed of charging the mobile phone is It's a bit slow, but it's better than nothing. Because in an emergency, someone can resurrect the mobile phone and turn it on for emergency treatment. It still plays a role.

After 2 hours and 49 minutes of reverse wireless charging, the Huawei Mate 30 charged the iPhone 11 Pro with 47% of its power and 20% of its own power remaining. The reverse wireless charging function automatically turned off when the power was below 20%, and the remaining power guaranteed itself Endurance requirements.

My friend ’s mobile phone is out of power. Charge him with his Mate 30 to relieve his urgent needs; or if his sports bracelet or TWS ’s Bluetooth headset is out of power, he can “resurrect” and use it immediately. , You do n’t need to carry the charger of the headset bracelet when going out. The actual experience of the Huawei Mate30 wireless reverse function experience is good, providing another type of battery life guarantee options for other devices.
