In fact, before buying the Xiaomi USB charging head (dual-port), I bought an Anker dual-port quick charging head for the double 11 in last year, but it was basically idle... After the test of Xiaomi USB charging head, the USB tester The use gradually became familiar, so I wanted to simply test the Anker dual-port quick charge head to see how this charging head performed...
Reasons to purchaseLet's talk about Anker:
It is also said that Anker is a brand of flowering wall incense outside the wall. Before the flagship market was overseas, it only recently began to enter the country. The origin appears to be in Changsha. If you want a better price or the latest product, you can use Amoy or Amoy. As far as Anker's products are concerned, product innovation is good and outstanding workmanship, so its reputation is also good and the market recognition is high.
Buy this dual-port quick charge head, or look at its dual-port fast charge. As to why we bought it, we will say below.
Put a purchase link, pick up the sea to trouble Tao, plus double 11 discounted 10 yuan, on the x treasure to solve:
Anker Dual Qualcomm QC3.0/2.0 Quick Charger Multi-Port USB Smart Fast Charger 178.2 yuan Lynx Featured Direct Link Appearance 
The box is fresh and white with blue. Blue also matches the color of the Anker logo.
There are various parameters on the reverse side of the box, as well as the origin.
Open the lid with a ... cover? Strengthen brand awareness?
The original box is such a structure.
↑ Instruction and charging head. The other is gone.
↑ Charging around the charge head, good workmanship. This side has a logo, bumpy, very delicate.
There is a sign of QC3 on this side and the sign of Anker's so-called powerIQ technology. PowerIQ technology is probably able to intelligently recognize the electronic devices connected to each interface, and automatically adjust the current output, so as to provide the fastest and most stable charging for electronic devices to achieve the best charging performance.
This side of the crucible side is a variety of parameters: wide voltage; 3.6-6.5V can provide a maximum current of 3A; 6.5-9V can provide a maximum current of 2A; 9-12V can provide a maximum current of 1.5V.
It is a pity that the plug cannot be folded. The material is also iron.
This is the interface, blue interface core, looking very refreshing. There is a dot on the far left, which is the light sensor. There is a vertical bar on the side, that is LED lights. This is Anker's innovation, which can automatically control the brightness of the led according to the brightness of the light.
The LED is also blue. However, this light cannot be turned off... Although the brightness of the LED can be automatically adjusted according to the brightness, the brightness is still very touching on a dark night... It happens that you can only sleep in a dark bedroom and you can sleep when you sleep. phone charging……
Weigh the next. Length 64.8mm.
There is also a 66mm height. It is basically a square look. The thickness is forgotten, and the official figure is 28.5mm.
↑ Look at the comparison with the previously tested Xiaomi USB charging head (dual port).
The difference in thickness is good.
Oh, the difference is very big. Anker's charging head is really burly...
The last name was 135g. Not light. In view of this weight, this size plus plug is not foldable, travel is also OK, outdoor climbing even if it is inconvenient.
experience feelings
The test is still using a USB tester. Due to the small spacing between the two interfaces, only extensions are available.
The electronic devices used in the tests were ipad4, red rice 4 and Xiaomi's new 10000mAh charging treasure.
↑ Two interface conformance tests are all about 5V under no load.
The two interfaces are separately tested for QC2.0 5V stepping current. It can be seen that all are similar, there is no line compensation, the maximum voltage is 5.02V, the maximum current is 3.8A and 3.5A, the maximum power is 18.3W and 16.8W respectively.
The two interfaces were separately tested for the QC2.0 9V stepper current. It can be seen that the difference is not significant, there is no line compensation, the maximum voltage is 9.04V and 8.99V, the maximum current is 3.7A, and the maximum power is 32.8W and 32.6W, respectively.
↑ The two interfaces are separately tested for QC2.0 12V stepping current. It can be seen that the difference is not large, there is no line compensation, the maximum voltage is 12.06V and 11.96V, the maximum current is 2.94A and 2.96A, and the maximum power is 35W.
The QC3 test was performed on the two interfaces, and the difference was not significant. The initial voltage was 4.62V and 4.816V, the maximum voltage was 12.065V and 11.968V, and the minimum voltage was 3.6V and 3.595V, respectively.
From the above test, we can see that the difference between the two interfaces is not large, and basically can achieve the functions of QC2.0 and QC3.0.
The two interfaces are connected to the ipad. It can be seen that there is a difference, but the voltage and current data are not very good.
↑ The two interfaces are connected to red rice 4 respectively. It can be seen that there is a difference, but the basic realization of fast charge.
↑ The two interfaces are connected to the millet charging treasure. You can see that the difference is small and you can achieve fast charging.
From the above test, it can be seen that when charging a single device, it is basically able to achieve fast charging, but charging the ipad is generally performed. (This is related to ipad power? When I wrote this original, I suddenly remembered that the ipad battery was nearly full during the test...)
This is the red rice 4 and millet charging treasure, respectively, measured red rice 4 charging voltage 8.01V, current 1.41A, 11.3W. Millet charging treasure charging voltage 8.886V, current 2.034A, 18.07W, can basically achieve fast charging. However, the realization of fast filling of red rice 4 is triggered manually...
This is the millet charging treasure and ipad, respectively, measured millet charging treasure charging voltage 8.43V, current 0.79A, 6.672W. Ipad charging voltage 4.943V, current 1.153A, 5.7W. This performance is very general, especially the charge current of millet charging treasure, it is not scientific......
This is the red rice 4 and ipad, respectively, measured red rice 4 charging voltage 4.68V, current 0.46A, 2.157W. The charging voltage of ipad has not changed much before, and the charging voltage is 4.941V, current 1.167A, and 5.77W.
From the above performance point of view, the charging current obtained by the electronic device connected to the USB tester without extension cord (the above 3 cases of Xiaomi Charm and ipad) is still normal. The charging current obtained by the electronic device connected to the USB tester using the extension cord (red rice 4 and millet charging treasure in the above 3 cases) is abnormal. As a result, ambiguous speculations that due to factors such as the use of extension cords and the resistance of the USB tester itself, the powerIQ technology does not function properly, giving correct charging current to different electronic devices. Of course there are other possibilities. This can be explored.
to sum upIn general, the charger performance is still outstanding, the overall workmanship is exquisite, LED lights have a certain degree of innovation. The performance of a single electronic device is outstanding. When the two electronic devices are charged, the output performance is quite different, and sometimes it is necessary to insert or pull many times or decoy in order to achieve fast charging, and the output is not normal due to reasons such as test equipment. Of course, this conclusion may be incorrect and there is a certain amount of speculation. In addition, due to the special lifestyle, and the size of the weight and the inability to fold the plug, the dual-port quick charge head is also used occasionally during the daytime... Personally think that if you do not care about the volume and bright LED, Still worth buying.
