 Mobile phone wireless charging full review: when buying wireless charger you need to know that? In the second wireless charging efficiency and other aspects, QI standard wireless charger.

In the previous article, we analyzed the working principle of the wireless charger, electromagnetic induction, and the wireless charging equipment available in the market, this article will analyze the wireless charger which also need to pay attention to?

Different mobile phone need to match the different specifications of the wireless charger, now the wireless charging equipment 5 W, quick charge 10 W, 10 W combination 7.5 W. But for most of the mobile phone, support 10 w output wireless charger is enough. In addition, many wireless charger not attached with the head and cable, need to choose according to the input power and quick charge standard.

The wireless charging pad end (wireless charging PCBA board):

The current mainstream wireless charger Qi is the main use of the configuration of the support of 10 W output, conversion rate and is equivalent to about 5 W ~ 7.5 W received power.

But this year has been using the configuration standard wireless charger, can support maximum of 15 w output power, equivalent to the received power of can reach about 10 w, can greatly increase the speed of wireless charging for mobile phone.

Mobile terminal

Since wireless charging board has the power limit, so mobile nature, too. The current mainstream smart phones support 5 to 10 w output power of wireless charger.

For example, the samsung Galaxy S phones can support 10 W wireless charging, and 8/8 Plus apple iPhone and iPhone can support wireless charging 7.5 W, X, of course, converted to receive power will be lower.

In addition, support for relatively fast wireless standards of smartphones also launch this year, there are the familiar SONY and LG V30 XZ2 series series, the received power can reach about 10 w, but need to match the same configuration support wireless charger.

Iphone 8/8 Plus and iPhone X although compatible Qi standard, but not all Qi wireless charger can make it at 7.5 W quickly.

In addition to wireless charger plate, working power, also need to pay attention to?

Wireless charger foreign body detection

Wireless charging foreign body detection should be wireless charger the most basic security functions, when cell phones and wireless charger sandwiched between metal foreign bodies, wireless charger will perceive and power outages, prevent metal foreign bodies from overheating.

But the function parameter is impossible to judge light see propaganda, only through the measured look at specific performance, on the market most wireless charger is qualified in terms of foreign body detection.

Heat dissipation problems

Wireless charger output power is not constant, and the peak power mainly depends on the design of the wireless charger materials and thermal radiation, we more recommend purchasing models equipped with active cooling fan, while thick point, but generally the output peak power of time is longer.

Charging distance

Qi wireless charger in the distance is about 3 to 10 mm, so every case also can charge, take off your phone cases do not need to charge.

Iteration, along with the development of the Qi standard wireless recharging costs have come down slowly, about one hundred yuan of product more and more, its experience cost is low. Millet huawei are currently trying to join the wireless charging for its products, wireless charging function can be expected in the next two years has great popularization.
