Qualcomm Xiaolong Technology Summit in 2017, Qualcomm official to bring you two new products, Qualcomm QC4 + charger, car charger. This is the world's first QC4 + Qualcomm certified products. At present, these two products have arrived Charging head network editorial department, Xiao Bian today to bring QC4 + charger out of the box and compatibility testing.
The overall blue and white color packaging, printed on the front appearance of the product picture; name 'QUICK CHARGE 4+ TRAVEL CHARGER'; by Dongguan Yi Electronics Co., Ltd. (Ever Win) design and production.
The back of the box, all English description.
Both sides of the box are the trademarks of Ever Win and Qualcomm and the words of 2017 Qualcomm Xiaolong Technology Summit.
This QC4 + charger uses a common black PC material shell, the side part of the frosted charger as a whole four-sided pyramid shape, ridge at the corner transition.
The volume is much larger than the common QC3.0 charger.
With the pin section, the total length of the charger is about 61.6mm.
Net weight of about 78.2g.
This QC4 + charger is only equipped with a USB Type-C output interface, the following QC4 + logo.
Pin part of the non-foldable design, using the US regulatory standards, and compatible with the national standard.
Charger pin part of the non-magnetic.
The parameter part is also different from the common QC3.0: the input part supports 100 ~ 240V global voltage; the output supports four kinds of specifications of 5V / 3A, 9V / 3A, 11V / 2.4A, 12V / 2.25A.
Second, the test
The front power indicator lights up after the power is turned on. ChargerLAB POWER-Z KT001 is used to trick the QC4 + charger. The header shows USB DCP and QC2.0 to QC3.0 protocol.
Similarly, during the USB PD message, the header display supports PD3.0 protocol and has two fixed output positions of 5V / 3A and 9V / 3A. In addition, this product also meets the latest USB PD3.0 protocol PPS specification and has two adjustable voltage ranges: 3-5.9V 3A or 3-11V 3A.
From the agreement in the above identification can be seen, This QC4 + charger is compatible with its own QC3.0, QC2.0 fast charge program, and also supports the USB IF Association USB PD3.0 PPS specification developed.The following is the actual test of various devices:
1, for the QC protocol equipment, this QC4 + charger millet 5, Sony XZ Premium two phones better compatibility, support QC3.0 fast charge.
2, for the USB PD protocol device, this QC4 + charger can support some devices fast charge, such as Huawei mate 9, iPhone 8 Plus, Meizu PRO 5 and Nintendo Switch; but there are some PD devices failed to achieve fast charge, such as New MacBook.
3, for Apple devices, This QC4 + product does not support the Apple 2.4A protocol, can not charge the iPad Air2 full speed, does not support the iPhone 7 full charge.
4, do not support the other protocols fast device, but because the charger and the phone support USB DCP charging protocol, so some of the tests did not achieve fast charging phone in the DCP charging protocol.
To some USB PD mobile power supply, can support USB PD fast charge. Which RAVower and purple rice two mobile power charging, the charger is in the 27W maximum output state; the other three mobile power also have reached the maximum charging power.
to sum up
As the world's first through Qualcomm certified QC4 + charger, the package is more concise. The product itself uses black PC flame retardant shell, body size than the market common QC3.0, QC2.0 charger a lot, the equivalent of a 30W USB PD charger size, and has four output parameters, providing a maximum output capacity of 27W.
Qualcomm QC4 + pioneered multi-protocol fast charge first, down to support their own QC3.0, QC2.0, QUALCOMM provided a continuation of its own fast charge agreement to enhance the user experience; In addition, it also supports USB PD fast charge, Help promote the popularization of Type-C interface and fast charge agreement unification.With Qualcomm support, the future cell phone charging standard will tend to be unified, but without losing individuality.
