Short battery life is a common problem of smart phones. In addition to increasing battery capacity, various fast charging technologies have become one of the selling points of mobile phones. However, mobile travel always depends on mobile power, so there is a mobile power that supports fast charging. As one of the professional mobile power manufacturers, Anker has its own power IQ intelligent quick charge technology chip products. Today, we use its products that support the USB-C interface to say how much better than its predecessor products.
Appearance and configuration
From the packaging styles of several Anker products used before, PowerCore+20100mA USB-C mobile power supply is no exception. White is the main color of the box. As Anker products are positioned in the global market, the printing language of the packaging box is English.
The product card and product manual in the packaging box are also its consistent style.
After removing the protective film, you can see the black aluminum alloy shell of PowerCore+20100. On the left side of the front is the product logo, on the right is the power key, and on the top is 10 led lights for power display. Press the button to turn on one light, which means that the remaining power is 10%. Compared with the four lights of the common mobile power supply, the remaining power display is more accurate.
From the side, the aluminum alloy shell adopts the sanding process, and the shell edges at both ends adopt the 45 degree trimming process, which can bring better hand feeling and visual effect.
PowerCore+20100 is equipped with two USB interfaces that support IQ smart charging as standard, and the other one is USB-C fast charging interface that supports bidirectional input and output. It is a rare mobile power supply that can charge three devices at the same time.
The other end is the product parameter, which supports 5V-2.4A input, 5V=6A output, and the maximum output current of a single port is 3A, which is enough to meet the current charging needs of mainstream equipment.
Anker has always attached great importance to the accessories of mobile power supply, without exception, it provides power cord and its unique style of mesh material storage protection bag, which is more masculine and more wear-resistant than velvet bag. The three power cords are also different. They are Type-C to Type-C USB-A to Type-C、USB-A to Micro USB， It can meet the needs of different equipment.
Compared with the appearance of the previous generation QC2.0 10000, PowerCore+20100 has doubled its capacity, doubled its volume, and reached 463.5g in weight. However, compared with the previous generation's single output interface, the three output interfaces are more practical.
Practical experience
First discharge the original power of PowerCore+20100, and then use the USB voltage and current meter to monitor the charging. When the charging is completed, the power indicator lights up, and the cumulative input power is 18213mAh.
Compare the output current with the LeEco 2 mobile phone that supports fast charging. The actual output current of PowerCore+20100 is about 1.46A, 40.38% higher than 1.04A of QC2.010000.
The Battery Monitor Widget Pro software is used for charging analysis. It takes only 10 minutes to charge 10% of the phone's power, and the charging speed is faster than that of ordinary mobile power supplies.
When PowerCore+20100 is fully charged, the cumulative output is 12978mAh after discharge, and then it is charged. The cumulative input power is 18501mAh (18213mAh last time). The author also mentioned the common sense of mobile power supply. The voltage of its internal 18650 cell is 3.7V, and the output voltage is 5V. The voltage conversion is achieved through the step-up or step-down capacitor of the circuit board. The conversion efficiency is 87.25% according to the following calculation, which is good. We can also conclude that the input loss is 29.85%, and the power loss of this part is 29.85%. The more obvious the loss is, the better the internal circuit design is.
(12978mAh × 5000mV) / (20100mAh × 3700mV)=0.8725
1-(12978mAh × 5000mV) / (18501mAh × 5000mV)=0.2985
Another practical point of PowerCore+20100 is that the Type-C interface mentioned above can be used not only as an input interface, but also as an output interface. At present, the Type-C interface has been gradually popularized on mobile devices, and its application will be more and more extensive. The three interfaces of PowerCore+20100 output at the same time. The maximum output current of a single port is 3A, and the maximum total output current of three ports is 6A, which is enough to meet the current needs of users.
Write at the end
In the mobile power market full of counterfeit, off brand and brand products, Anker adopts its own power IQ smart charging and fast charging technology, which is of excellent quality and trustworthy. 20100mAh can actually output about 13000mAh of electricity, which is enough to fully charge the mobile phone for 5-6 times, and can better meet the needs of outdoor activities.
Finally, I also summarize my personal opinions:
Advantages: 1. Power IQ has fast charging speed and can intelligently identify different charging devices; 2. It supports dual USB-A and single Type-C output, and can charge three devices at the same time; 3. The actual conversion efficiency exceeds 85%, and the quality is good; 4. 10 grid power indicator light, more accurate display of remaining power.
Disadvantages: 1. The plastic panels on both sides are easy to scratch and affect the appearance; 2. The high price is also one of Anker's characteristics.
