Qualcomm Quick Charge, one of the main players in the fast charge camp, has evolved into the third generation. ANKER， The sales volume of USB charging related equipment in North America tops 1, and has always been a follower and supporter of Qualcomm QC's fast charging technology; We have seen several USB charging devices produced by ANKER that support QC2.0. Recently, ANKER closely followed the pace of QC and launched a new QC3.0 fast charging equipment. Today I share with you ANKER QC3.0 fast charging package.

ANKER QC3.0 fast charging package includes three devices: ANKER QC3.0 two-way mobile power supply, ANKER QC3.0 five port desktop charger, ANKER QC2.0/3.0 dual port car charger; Covering a variety of application scenarios from home to car, from fixed to mobile, it can be said that "one set is easy to charge." On the outer packaging, ANKER unified white and blue color paper boxes are used, with simple style and environmentally friendly materials. ANKER has been deeply involved in the European and American markets for many years. Both the product itself and the commodity packaging as an add-on are close to the times and becoming increasingly mature.

The information of the two products in the package is marked on the bottom of the box by sticking labels. In fact, these labels are additional Chinese labels to adapt to the domestic sales market; On the package of the uncabeled QC3.0 two-way mobile power supply, we see printed labels in English. Of course, because it is an experience product, the packaging of mobile power supply does not represent the final packaging form for official sales in the domestic market.

Part I: ANKER A1311 QC3.0 bidirectional 10050mAh mobile power supply

Let's first take a look at this ANKER A1311 QC3.0 two-way 10050mAh mobile power supply. The external packaging will not be described. From the label on the back, we know that this power supply belongs to ANKER's PowerCore+series, model A1311, supports QC3.0 two-way fast charging, and its design capacity is 10050mAh.

All paper packaging, the product surface is protected by translucent plastic bags. The entire package does not reserve too much buffer layer, and the packaging box basically fits the product shape, so the entire package is very compact.

Take out the mobile power supply. In addition to the user manual and user experience card, there is an independent blue paper box. Friends familiar with ANKER products may know that it is a box for placing accessories.

There is a nylon mesh storage bag and a charging cable with Micro interface in the accessory box. The standard storage bag and charging cable have always been the usual practice of ANKER PowerCore+series mobile power supply, but small accessories show the importance to consumers in details.

In terms of appearance, the ANKER A1311 QC3.0 two-way 10050mAh mobile power supply has not changed much, and it can even be said that it has followed the classic shape of the previous PowerCore+series: aluminum alloy integrated shell, rounded corners on both sides, front logo+round function keys; This design appears on several mobile power supplies in the same series, of course, the inheritance of this appearance is not contradictory to the innovation of technology.

The surface of the mobile power supply still adopts the anodic oxidation and sandblasting process. For aluminum magnesium alloy materials, this process is really the best choice for both beauty and function. ANKER's logo shows the true color of aluminum by laser etching, especially on the matt black background.

This is a very classic ANKER mobile power function button integrated with 10 LED power display. The slightly depressed surface of the button gives a good feel when pressing. At the same time, 10 LED power can display real-time power more accurately.

The Qualcomm Quick Charge 3.0 logo highlighted on the back, the most advanced fast charge technology, is certainly worth highlighting.

The input and output part is very simple. A Micro port is used for input and a standard USB port is used for output. The green socket is used for output to distinguish the general non fast charging output. From the "IQ" sign on the side, this mobile power supply also supports ANKER's PowerIQ intelligent recognition charging technology.

The edge of the mobile power supply is finely chamfered by CNC, which avoids the discomfort brought to users by sharp right angles of metal materials.

The information on the bottom is very detailed. It can be seen from the parameters that this mobile power supply supports the bidirectional QC3.0 standard, that is, the input and output can be intelligently adapted to the 5-7V, 7-9V, 9-12V interval voltage. In fact, the core technology of QC3.0: the optimal intelligent voltage negotiation algorithm (INOV) It can adapt intelligently within the range of 3.6V-12V, but currently the voltage below 5V is seldom used, so ANKER chooses a labeling method similar to QC2.0 ClassA. In addition to supporting the QC3.0 protocol, the input also supports the normal 5V/2A input. For friends who do not have a fast charging head, they can also charge normally, but it will take longer. We will leave this to you later.

The size and weight of mobile power supply have always been the most concerned aspect of consumers based on performance, because this is directly related to the portability of mobile power supply, and no one wants to carry a big brick all day long. According to the actual measurement, the length, width and thickness of ANKER A1311 QC3.0 two-way 10050mAh mobile power supply are 98.5 * 60.5 * 22.5mm, and the weight is 241g. As a 10000mAh level metal shell mobile power supply, it is still small in size and weight.

Now we enter the data testing phase. This paper strives to pass a more detailed test to let you have a deeper understanding of the technical parameters and compatibility of ANKER QC3.0 suit. As the saying goes, "It's a mule or a horse, and you can pull it out.".

This is the QC3.0 characteristic test chart. As mentioned earlier, the most significant difference between QC3.0 and the previous generation 2.0 is the optimal voltage intelligent negotiation algorithm (INOV). This technology enables the power adapter to intelligently adjust the output voltage according to the condition of the charged equipment. The adjustment range is 3.6V-12V, and the adjustment step is 200mV, thus breaking the QC2.0 ClassA fixed 5V, 9V With the limitation of 12V three gear output, the advantage of the improvement is that it can optimize the DC/DC efficiency in the mobile phone, reduce the loss, and eliminate the problem of mobile phone heating caused by voltage switching inherent in QC2.0.

5V gear output test, the maximum output is 4.94V/3.00A/14.8W, and there is ANKER's unique stage voltage drop compensation technology, the maximum 3A current meets the design parameter requirements.

In the 9V gear output test, the maximum output is 8.97V/2.10A/18.8W, slightly exceeding the nominal parameters, and this voltage segment does not start voltage drop compensation.

12V gear output test, the maximum output is 12.13V/1.60A/19.4W, the overall performance is similar to that of 9V gear, after reaching the maximum output power, the output is reduced; This voltage section also does not start voltage drop compensation, but can maintain a voltage above 12V before reaching the maximum output power.

In order to make you have a more intuitive understanding of the differences in charging efficiency and time consumption among conventional 5V, QC2.0 and QC3.0, the author used the above three methods to charge this mobile power supply, and discharged the remaining power to automatic shutdown before the test. The above figure is the conventional 5V charging curve. It can be seen from the figure that the whole charging process takes about 5 hours, the input energy is 42.93Wh, and the charging efficiency is 84.3%; The charging current is basically maintained at about 2A, and the charging power is about 10W.

This is the charging curve of using QC2.0 charger to charge this mobile power supply. The charging process takes about 3.5 hours, saving nearly 1.5 hours compared with 5V mode. The input energy is 41.02Wh, and the charging efficiency is 88.2%; The charging current is maintained at 1.7A, and the charging power is about 15W. From the data, the QC2.0 mode has greatly improved both in charging time consumption and charging efficiency compared with the traditional 5V mode.

Finally, QC3.0 charger is used for charging. The charging process also takes about 3 and a half hours, the input energy is 41.92Wh, and the charging efficiency is 86.3%; The charging current is about 2.1A, the voltage is about 7.2V, and the charging power is about 15W. The measured data shows that QC3.0 has no obvious advantage over QC2.0 in terms of charging time consumption and charging efficiency. The two are evenly matched. What's the difference? The difference lies in the voltage. On the basis of keeping the charging power at 15W, The optimal voltage negotiation algorithm (INOV) of QC3.0 starts, reduces the input voltage to about 7V, and increases the charging current, thus reducing the loss of the DC-DC conversion circuit inside the mobile power supply. The most intuitive feeling is that the heating capacity of the mobile power supply decreases during the charging process, which is the core technology of QC3.0. In short, QC3.0 not only improves the charging speed, INOV pays more attention to energy consumption and safety, so QC3.0 is not simply "fast".

Then look at the discharge performance of the mobile power supply. First, carry out constant current discharge according to the nominal 5V/3A, release 28.75Wh of energy in total, the line end conversion efficiency is about 79.5%, and the whole voltage is firm and straight.

9V/2A mode constant current discharge releases 27.94Wh of energy, the line end conversion efficiency is about 77.2%, and the voltage curve remains straight.

Then look at the 12V/1.5A constant current discharge, which releases 27.95Wh of energy, and the line end conversion efficiency is about 77.3%. From the perspective of the conversion efficiency of the third gear line terminal, the conversion efficiency is somewhat low. Of course, there may be some factors affecting the insufficient activation of lithium batteries.

The final test link is the output compatibility test. The instrument shows that the mobile power supply supports Apple 5V 2.4A or DCP 5V 1.5A. In the device measurement, the author used Apple devices, QC2.0 and ordinary mobile phones for testing, and the test results are summarized as follows:

measure The test results show that ANKER A1311 QC3.0 fast charging mobile power supply is compatible with all digital devices in the test, including Apple.

Part II: ANKER A2054 QC3.0 five port desktop charger

from There is little difference between the outer packaging of ANKER series and that of ANKER series. Due to the limited space, the author will not introduce it in detail; This ANKER A2054 QC3.0 five port desktop charger belongs to ANKER Powerport charger series, and the label details the product information.

In the package of the domestic version, there are more product certificates, warranty cards and lists of toxic and harmful substances of electronic information products necessary for domestic sales. The accessories are still packed in a separate blue paper box.

Accessories include an "8" AC cable, binding tape and a piece of double-sided adhesive tape for desktop fixation.

The workmanship of the "8" AC cable is very good. The plug part also has a protective rubber sleeve to prevent oxidation. The cable is neatly bound with a binding belt, and the details are in place.

Compared with the previous generation of Powerport series desktop charging products, ANKER has adopted this round shape with 12 edges treated with circular arc in its new products. This shape has improved the grip feel, but the two side seams deliberately left and the fit with the desktop have caused many complaints.

The output interface adopts symmetrical design. From top to bottom, there are power indicator, 2 * QC3.0 output port and 3 * ordinary output port. The output port also uses blue and black sockets to make a clear distinction.

The indicator light is still blue. Due to the existence of long light guide pillars, the light is soft, and there is no discomfort caused by strong light.

The output port identification and product information are located on one side of ANKER A2054.

The output performance of the two QC3.0 ports is the same as that of the aforementioned mobile power supply, while the other three PowerIQ ports support 5V/4.8A (maximum 2.4A for a single port) output.

The rear is a detachable 8-character power socket. This design fully takes into account the needs of users who need to move, so this is a desktop and mobile charging device.

Compared with the palm, this charger is relatively large. After all, it is a charger mainly used for desktop.

Without saying much, go directly to the key testing link. QC3.0 characteristic test shows that the 200mV voltage rise and fall adjustment is stable and in place, and the curve is very beautiful.

Step test of 5V current of QC3.0 port (according to the author's experience, the output of multi port charging equipment is mostly in parallel mode, so this test only tests one output port of QC3.0 and one output port of PowerIQ, including the compatibility test below). The maximum output is 4.80V/3.60A/17.3W, which exceeds the nominal parameter value. Unfortunately, this series is not equipped with line loss compensation technology.

The maximum output of 9V gear current step test of QC3.0 port is 8.73V/3.60A/31.4W, which is much higher than the nominal parameter value, leaving a large margin for power.

In the current step test of QC3.0 port at 12V gear, the maximum output directly exceeded the range limit of the test equipment of the author, reaching 11.75V/2.98A/35.0W. The performance is very strong.

Check the current step of PowerIQ port (ordinary output port). The maximum output is 5.14V/4.00A/20.6W, which also exceeds the measuring range of the measuring equipment. Although there is no line compensation, when the current reaches 4A, the voltage is still at a high level above 5V, which performs well.

The compatibility test of both interfaces shows that they support Apple 5V 2.4A or DCP 5V 1.5A mode, which means they can support Apple 2.4A charging mode.

The measured output compatibility of ANKER A2054 QC3.0 five port desktop charger is shown above, which proves that both interfaces support Apple mode. As it is a comparison test between the ordinary port and the QC port, it can be seen from the figure that digital devices that support the QC fast charging protocol (such as Xiaomi 4, Beiste fast charging version mobile power supply and ANKER A1311 two-way QC3.0 mobile power supply) obtain greater charging power after being connected to the QC charger, which will naturally shorten the charging time and save users' time in the charging process.

Part 3: ANKER A2224 QC2.0/3.0 Dual port Mobile Charger

As usual, look at the packaging. This is a car charger that supports QC2.0 and QC3.0 respectively. It belongs to another PowerDrive+series of ANKER. The output parameters of the two ports are slightly different from those of the above two models. You can directly look at the pictures, and the author will not repeat them.

This car charger is also packaged for domestic sales, so the description materials in the package are the same as those of the previous desktop five port charger, but this car charger is a car charger body without additional accessories.

In terms of appearance, this series of mobile chargers still have heritage. The same appearance appeared in the previous generation of A2221 QC2.0 dual port mobile charger. The power taking end is a high gloss piano paint finish, and the tail is an aluminum alloy cast casing. A ring of red light guide ring is inlaid at the connection between the two. In addition to the red light guide ring, the overall tone is the gray and black tone of ANKER series.

The red light guide ring power indicator is very interesting. It will adjust the light to be bright and dark with the rise and fall of the voltage. In the dark interior space, the light intensity can be used to preliminarily judge whether the QC fast charging mode has been started without borrowing the instrument. The design is very user-friendly.

The product information is selected and marked on the power supply terminal, and various parameters are consistent with those marked on the outer packing box.

The two output ports are still symmetrically arranged, with QC3.0 output port on the left and QC2.0/PowerIQ output port on the right. Since both output ports are green sockets, and in the dark car, it is difficult to distinguish the two ports visually. I hope that future design can make up for this shortcoming.

Once again, we came to the performance test. The step test of the 5C2.0 port 5V current showed that the maximum output was 5.19V/2.60A/13.5W, which exceeded the nominal 2.4A current. At the same time, we saw the expected line compensation mode.

Step test at 9V gear of QC2.0 port, the maximum output is 9.18V/2.60A/23.0W, and the measured result is similar to that at 5V gear.

QC2.0 port 12V step test, the maximum output is 12.24V/2.50A/30.6W, the output greatly exceeds the nominal value, and the whole line compensation.

The maximum output is 5.18V/3.30A/17.1W through step test of 5C3.0 port at 5V gear, which is more powerful than QC2.0 port. At the same time, it is also wired compensation mode.

Step test at 9V gear of QC3.0 port, the maximum output is 9.10V/3.30A/30.0W, and the performance is adverse.

The maximum output of QC3.0 port 12V step test is 12.07V/2.90A/35.0W, which is beyond the range limit of the test equipment of the author without any doubt. On the whole, the output performance of this car charger is outstanding, which also conforms to the rule that DC-DC has higher conversion efficiency than AC-DC.

In the compatibility test of the QC3.0 interface, the instrument does not show that it supports Apple devices, and the next test will be carried out.

QC2.0 output port display supports Apple 5V 2.4A or DCP 5V 1.5A mode.

According to the actual measurement, the QC3.0 interface is indeed incompatible with Apple devices, but the QC2.0 interface is perfectly supported; In addition, both ports have good compatibility with QC equipment.

Summary:

ANKER QC3.0 fast charging package (ANKER QC3.0 two-way mobile power supply, ANKER QC3.0 five port desktop charger, ANKER QC2.0/3.0 dual port car charger) is a set of charging edge tools specially created for the era of QC3.0 fast charging. This one-stop QC3.0 fast charging solution meets various user needs. In terms of product performance, the three products all have good performance, especially the output power, which is really amazing. If we talk about the shortcomings, the ANKER A2054 QC3.0 five port desktop charger's missing line loss compensation and the ANKER A1311 QC3.0 two-way 10050mAh mobile power's low line end output conversion rate, if these two points can be supplemented and improved, then the ANKER QC3.0 fast charging package can be almost perfect.
