比快充快？如果快没人要快充了
前一阵在讨论usb线的问题有线都这么多讲究无线一边凉快去吧
无线从来都比不是有线
The Wireless Power Consortium (WPC) this week announced the latest version
of its Qi (pronounced "chee") wireless charging specification, which
provides three times the amount of power as the majority of in-market Qi
charging products. In fact, the new 15w WPC wireless spec offers the same
amount of power as many wired charging options available today for mobile
phones.

One of the biggest downsides of modern wireless charging is that it takes
significantly longer to power up devices than traditional, wired charging
cords. However, the new Qi spec could go a long way toward closing, even
eliminating, that gap. For example, Samsung's Adaptive Fast Charging cords
are some of the faster mobile phone power options available, and they
provide 15w, the same amount of energy as the new Qi spec, according to John
Perzow, WPC's vice president of market development.
The wait for 15w
Mobile devices need to be built to support the spec, and the majority of
existing phones with wireless charging, including the two Galaxy S6 phones,
will not be able to charge at the full 15w without some sort of adapter. The
Galaxy S6 phones support the 5w Qi standard — in addition to the current
PMA standard — and therefore will be able to charge at only 5w even if you
use a 15w charger. However, the new spec is backwards compatible, according
to Perzow, which means new chargers should still be able to power older
devices that support Qi.
Perzow also says it will be more expensive to build 15w, Qi-compatible
devices, at least for a while, so companies may still choose to use the
cheaper 5w or 7w specs. "You pay for power," he says.
In addition to the new specification, the WPC also released a set of the
test procedures and utilities needed to verify that products are compliant,
but it will still take time for manufacturers to design, test and build
chargers that use new Qi spec. In fact, Perzow says it can take as long as
two years to design new 15w chips or integrated circuits, though WPC members
have already been working with the spec and could presumably release
compatible products in the near future.
Perzow says Qi products are about to flood the market; he estimates that 55
million Qi devices were in use at the end of 2014 and that 100 million more
Qi gadgets will ship during 2015.
WPC's Qi is one of three leading wireless charging standards vying for the
top spot in the world of wireless power. The Power Management Alliance and
Rezence are also contenders, but WPC says its 15w spec is "a first in
wireless charging." Notable companies that back WPC include Belkin, HTC,
IKEA, LG, Microsoft, Motorola, Nokia, Panasonic, Samsung, Sony, Texas
Instruments and Verizon Wireless.

无线充电速度肯定不不上有线，不适合外出的时候救急。不过在家里/办公室用着方便
啊，随便搁着就能冲，对某些用防水盖子保护USB口的来说太重要了（比如三爽s5），
不至于过一段时间盖子被揪断防水成摆设。

不普及是因为苹果没上。因安卓的再不用无线就不理解了。反正我是办公桌，家里，床

果果上无线了，那20刀一根的线没人买了，你这不是剥夺果粉high的理由了么？

你写这么多有鸟用，根本不懂电子，无线充电标准比高通9v充电早多了，
无线充电就是电磁炉一个原理，你想加大电流没任何问题，
快充不一定合理，锂电池充电不好控制，大充电电流增加危险因素

everyone can join and see posts, no difference
There is a club called fly, they trade within their groups and point out
that the trading may violate airline's ffp policies.
I do not know how what the final decision is, it is totally out of my
control. So I decide to open it as club.
But it will be an open club to everyone ...

抄来的是不懂大牛来点普及教育吧
有线无线充电的对比
现在人比较着急所以要快充
