On the latest flagship mate 30 in 2019, Huawei continues this function. Let's take a look at the actual performance of Huawei mate 30's "wireless reverse charging technology".
Wireless charging power is off by default to avoid power loss. To turn on this function, we need toMobile phoneIn the battery interface, open "wireless reverse charging". At present, the power of the mate 30 mobile phone on Xiaobian's hand is 100%.
Use the wireless charger tester to test the voltage and current output by Huawei mate 30 wireless. The measured results are: voltage 5.33v, current 0.95a, power 5.06w, transmission frequency 132.2khz.
We have also tested Huawei Mate20 Pro wireless charging before. The output power of Mate20 Pro reverse wireless charging is about 3W, and the frequency is 112.1kHz. In terms of power, the power of Mate30 reverse wireless charging is higher than that of Mate20 Pro.
How about the actual charging? How much charge can you charge your phone in half an hour? The editor took one.IPhone11 Pro tests, another phone on the countdown function, set 30 minutes.
The battery capacity of Huawei mate 30 is 4200mah, and that of iPhone 11 Pro is 3190mah.
At present, the power of iPhone 11 Pro is 0% (the phone shuts down automatically). Put it behind Huawei mate 30. The wireless charging function is immediately turned on, and the screen lights up (as shown in the figure) to start charging.
After 30 minutes, 88% of Huawei mate 30's power is left, 12% is consumed, and the iPhone XS is charged to 9%.
How much can I charge in the whole process? Xiaobian fully charged Huawei mate 30 and discharged the iPhone XS to automatic shutdown, and carried out the reverse charging test of mate 30 on iPhone XS. The test lasted for 2 hours and 49 minutes, and the power consumption of mate 30 was reduced from 100% to 20%. IPhone 11 Pro charges from 0% to 47%. Finally, Huawei mate 30 has 100% - 20% power and iPhone 11 Pro has 0% - 47% power.
Why not test how much power Huawei mate 30 100% can charge iPhone 11 pro? Because Huawei mate 30 sets its own power below 20%, the system will turn off the reverse charging function, so as to avoid providing others with a battery life but shutting down the system itself.
Huawei mate 30 can charge mate 20 pro in reverse wireless mode.
Huawei mate 30 can bemillet9 reverse wireless charging.
Huawei mate 30 can beSamsungS10 Reverse wireless charging.
Huawei mate 30 can charge Huawei's freebuses 2 headset wirelessly.
Huawei mate 30 can giveAppleAirpods 2 headset wireless charging.
Because Apple watch was originally a private agreement of apple, not a standard "Qi" agreement, Huawei mate 30 was unable to charge it wirelessly.
The above is the test data, which is made into a table for everyone to watch. Huawei mate 30 has good support for mobile phones and earphones that support "Qi" protocol wireless charging, but for private protocol products like apple watch's early generation, it will not be able to charge them.
Charging head network Summary:
Huawei once again applies the "reverse wireless charging" function to mobile phones. In the actual test, the output power is about 5W. It's no problem to charge some small devices, such as sports bracelets, TWS earphones and other products. The charging speed of mobile phones is slow, but it's better than nothing. Because in an emergency, it can bring other people's mobile phones back to life for emergency treatment, or it can play some roles.
After 2 hours and 49 minutes of reverse wireless charging, Huawei mate 30 charged 47% of the power of iPhone 11 pro, leaving 20% of its own power. The reverse wireless charging function automatically turns off when the power is less than 20%, and the remaining power ensures its own endurance demand.
When a friend's mobile phone is out of power, use his mate 30 to charge it to solve the urgent need; or his sports bracelet or TWS Bluetooth headset is out of power, charging it can immediately "revive" and then use it. You don't need a charger with headphone Bracelet when you go out. According to the actual experience, Huawei mate30 wireless reverse function experience is good, which provides another type of endurance guarantee option for other devices.
