It is used to charge a power armor 18 that supports up to 15W charging, so I have no idea how it behaves (or if it actually reaches) 50W. The charger has a small fan at its base that activates automatically when charging and significantly lowers not only the temperature of the charger but also that of the phone! Specifically, the phone does not exceed 39 degrees, while with a simple 10W desktop charger it reached 47 degrees. So it charges faster and stays cooler, which is good news for battery life! Aside from the fan and the Ulefone logo, it is a "simple" and very overpriced wireless charger that should be noted, of course, for those who didn't notice that the packaging does not include the power supply. It will reach 15W or 50W only if you connect it with a mobile charger that you already have and that naturally supports the appropriate power output. There are two main problems with this wireless charger: The pad at the bottom that holds the phone is made of soft rubber and completely seals the phone's microphone, which in 99% of cases is also located at the bottom of the devices, so if you are charging the phone or if you simply use it as a stand, forget about calls, video calls, voice commands, etc., because the microphone hears nothing. In the Power Armor 18, in fact, since the speaker is located at the bottom right, we also forget about music! Apparently, over at Ulefone, one department doesn't communicate much with another to design compatible devices with each other, even if just for appearances! The other problem, more serious for me, which loses it a star in the rating, is that when the battery fills to 90%, the charger stops and continuously restarts charging, causing the device to blink constantly; it does this about 10-20 times until it reaches 100% and stops. Yes, charging to 100% is bad for the battery, but I don't know if this continuous intermittent charging does more harm in the long run. Due to the excessive price at which it is sold and the last problem I described, I would not recommend it as a charger. The only thing I appreciated about the design is the fan and the benefit that the battery and the device gain from the low charging temperature. I don't personally consider the problem with the microphone not being heard to be something terrible; anyway, even if we manage to make it work with a workaround (like sticking two rubber spacers at the bottom), the noise of the fan would still be heard by the caller since it is right underneath.

With the little use I have had with the wireless charger, it seems fine, and it charges the Ulefone Armor 23 Ultra very quickly. I didn't want the ports to be exposed to wear, but unfortunately, the USB port on the phone is exposed.

The charger was purchased for use with the Ulefone Armor 18 ultra. It works properly, as the company recommends it for this model. Along with brands like Apple, Xiaomi, Huawei, etc. When connected with a 5V power supply, only the horizontal charging coil works. With a quick charge wall brick - in my case 9V / 2A both charging coils work, horizontal + vertical. Then the cooling fan that the charging base (QI PAD) has can also operate.

I happened to read the post on 07/01/2025 that mentions a charging problem at 90%. There is no problem with the charger, only with the phone. The owner should update it. I write this from my personal experience. And one more thing, he mentions as a negative the absence of a power supply within the QI PAD. Personally, I do not know any company that has a power supply within the wireless charging.
