When I said, “What is the purpose of adding wireless charging?”, I meant that if there is no good wattage support, then there is not much need to add it. In other words, a user would think twice about whether it is really necessary for their phone. If it had been higher, maybe they would not even have thought about this situation at all, like 15W for example. That is what I wanted to explain.
Nothing was said about it not being usable. The speaker is not impossible anyway. If you follow the thread a little, we discussed whether it is high-quality or low-quality. Some people like it, some don’t—that’s what I meant. Similarly, with wireless charging, some people like that wattage output, some don’t. Everyone has different tastes and needs. We never said the speaker is impossible; we just said not to expect something very high-quality.
