AirPower 部分替代品 AirUnleashed 上市
在苹果的 AirPower 和山寨产品 AirUnleashed 之间，存在着不少重大区别。然而，最切合文章题目的区别就是，你真的可以买到这款山寨的产品。
在 AirPower 沉寂了一段时间之后，苹果于今年 3 月宣布放弃这个产品项目，称他们无法 “达到自己的高标准”。该公司几乎没有发布任何其他信息，但大多数报道都提到原因是工程问题，即密集排列的充电线圈会导致产品过热。
毫无疑问，很多杂牌公司都在盘算着推出无线充电板产品，而苹果决定在发布产品前放弃无疑在这个市场留下了一个 AirPower 大小的空白，很多产品都在等待填补这个空白。
AirUnleashed 采用的方法相当无耻，连极简风格的白色包装盒也是从苹果设计部门那里偷师的，充电板本身就更是如此了，它采用了跟 AirPower 相同的药丸外形设计，虽然颜色是稍有不同的灰白色（奶油白？象牙白？）。
这款充电板的表面有一个小凹圆，而它的两侧则标有两个 “+” 符号。AirUnleashed 的设计师为三款苹果产品（iPhone、Apple Watch 和 AirPods）指定了三个不同的位置。不同于 AirPower 传说中多层重叠的充电线圈，AirUnleashed 配备了三个充电线圈，并且为不同的设备准备了不同的充电功率（分别是 7.5 瓦、2 瓦和 5 瓦）。
在某种程度上，你可以交替使用这些充电线圈。但出于各种原因，我们最好还是按照额定功率使用。不过，由于 AirUnleashed 采用了 Qi 标准，因此它能够兼容品类相当广泛的无线设备。
在我把 iPhone 和 AirPods 2 放到充电板上之后，它们马上就进入了充电状态。不过，我放上去的 Apple Watch 则没有反应。我就此联系了 AirUnleashed 的厂商，对方表示我需要升级到最新版本的 watchOS，这一招似乎确实能够解决问题。AirUnleashed 只配备了三个充电线圈，这意味着你得把设备放在正确的位置。即便在升级了 Apple Watch 的操作系统之后，我在找准位置方面仍然遇到了些困难。
AirUnleashed 的售价是 99 美元，比传闻中 AirPower 的价格便宜了 50 美元。奇怪的是，99 美元并不包括插头。如果要选购 AirUnleashed 的插头，你还得再破费 14 美元。考虑到 AirUnleashed 是一款山寨货，我觉得似乎没有必要再买他们的插头。
粗略地在亚马逊检索一番，我们能够找到不少 AirPower 风格的廉价无线充电板，它们似乎都采用了类似的三线圈解决方案。对于那些产品，我无法做出任何保证，但至少就 AirUnleashed 来说，我试用几小时后发现效果还不错。
