过去的2019年seo468，OPPO等国产手机厂商陆续加入WPC无线充电联盟，开始在无线充电技术方面发力。差不多时隔一年，OnePlus一加也正式加入WPC的阵营，悄悄为接下来的无线充新机做准备。盘点刚刚过去的一年，seo468我们也惊喜的发现目前支持Qi无线充电的手机也已突破250款，以及更多值得回首的诸多大事件。

苹果作为行业的风向标，在过去的2019年，苹果取消seo468了AirPower无线充电板，给满心期盼的所有人泼seo468了一盆冷水，这无疑对行业带来巨大冲击，不少企业纷纷失望离场。随着2020年的到来，供应链开始传来不少好消息，据透露2020年上半年苹果或将推出小型无线充电板以弥补至今没有自家无线充电器的缺憾。

此外，iPhone 9（SE2）也即将发布，新机定位瞄准了至今依然数量庞大的iPhone 6系列用户群体，据传在三千元以内价位支持无线充电和USB PD快充。这一切预示着，2020年无线充将会迎来新一轮增长。

自从2017年9月，苹果发布旗下首款Qi认证的iPhone手机开始，充电头网一直在每月持续跟踪WPC无线充电联盟Qi会员的数量变化，亲身见证了其爆发式增长的全过程：2019年1月份，Qi会员数量达到巅峰状态，共计661家。

时隔一年，充电头网再次统计Qi会员情况，最新数据显示2020年1月份会员数量为584家（截止到2020年1月31日），同比下降11.6%的比例。

关于WPCWPC无线充电联盟是全球首个无线充电的标准组织，是移动设备行业主导标准“Qi”，以及Ki 无线厨房标准的制定者。全球范围内会员众多，包括苹果、华硕、贝尔金、博世、佳能、戴尔、德龙、谷歌、海尔、华为、宜家、联想、LG、松下、飞利浦、三星、索尼、小米和 OPPO 等580多家公司会员。
