@lqcc 温度决定速度，实际差距远比纸面参数小，甚至倒挂。我用了这么久对充电速度没有任何不满，相比之下，其它充电器充电导致的手机发烫更令人不悦，PD 的设计相比 Apple 更优雅、实用，可以单手取放
7.5W CHARGING VS. 15W CHARGING: IT DON'T MATTER THAT MUCH.
「 When buying wireless chargers there's a lot of misplaced emphasis on the charger's wattage rating. It's an easy stat to be misled by: 15W is almost twice as powerful as 7.5W, so it must be twice as fast, right? Nope, not even close. And we're not just saying that, we've tested the snot out of it.
Some phone manufacturers have proprietary charging protocols (Apple 15W, Samsung 15W) that are not obtainable by 3rd party manufacturers. This means when you put an Apple phone on, say, a PD Wireless Charging Stand, the max charging wattage you'll reach is 7.5W and not 15W. That sounds like a big difference, but in practice (and over numerous lab tests) the relative charging performance is quite similar. In practice, the difference between charging speed with an Apple charger and a Peak Design charger are imperceptible.
The main reason for this is that most phones cannot sustain these high charge powers for more than a short period of time before they heat up and need to reduce charge power for the long remainder of the total charging time. In other words, just because a charger is 15W doesn't mean it always charges your phone at 15W. Most of the time, it will charge your phone at a much lower wattage.
In practice, the time it takes to fully charge your phone depends on a huge range of factors. Your phone model, battery age, power source, case-charger alignment, and—most importantly,—ambient temperature all affect charging speed. Wireless charging is not as fast as corded charging no matter what charger or phone model you may have. If you want the best performance possible you should try and keep your charger as cool as possible. 」

@wangedenr 这个是 MagSafe 15w ，iOS 会自动控温，发热也会影响实际充电速度，不要只看纸面参数

推荐 Peak Design 的 Wireless Charging Stand ，相比用过的 Apple 和 Belkin ，散热控制更好，无论是充电器本体还是 iPhone 到充满都几乎 0 发热，一台手机用了半年天天充，电池还是 100%（长期温度过高会影响电池寿命）。

心态的不同吧，如果主要目的是被迫或主动的想要寻求另一半，那大城市可能会更高效一些。纯玩当然是新鲜、体验舒适的更好玩，旅居需要考虑目的与成本的平衡，两者有所差异。
我们情况有些类似，但个人喜欢户外运动，旅居是偏好自由、新鲜的生活，没有目的性。
浙江农村的房子也不便宜，从理财角度，大趋势已经变了，现在哪里买，未来除非变天，都会被割。找对象充裕的可支配收入才是王道，不花出来租房还是自有不重要，水到渠成随时可以上车，在意质疑这点的人家也看不上几百万的刚需房。

@zzzkkk 买辆车，不拘于一地，只是作为远程工作、休整时的据点，这些城市周边旅游资源都非常丰富，全国各地游客很多，住腻了就换个地方，有钱又有闲才是你的最大竞争优势，遇到了情投意合的对象再按对象的意思走呗。
在杭州被房贷捆住或被掏空，日常开销大，你觉得“档次够”的对象要求也高，绝大多数人眼里远程工作都会被视为收入不稳定，除非你愿意交出收入支配权。

去旅游城市租房住个两年吧，旅居的同时也有机会遇到更多的人，相信那时候会有更清晰的答案
