Smartphones have driven the development of various accessory industries, especially mobile power. With the thinner body, stronger hardware configuration and larger screen, the battery technology has not been improved. Mobile power has become a necessary product, and a product with large capacity and safety is undoubtedly the most desirable.
The CP-B20 is the largest new product of Sony Cycle Energy series, with a capacity of 20000 mAh, which can be said to be quite exaggerated. Of course, if only the capacity is large, it will not show Sony's black technology. Sony CP-B20 uses Sony's original polymer lithium-ion battery. Based on Sony's own hybrid gel technology, it can guarantee an ultra long service life. The official claims that after 1000 times of charging and discharging, it can still maintain more than 90% of the usable capacity.
CP-B20 doesn't have much to say about packaging design. Due to the exaggerated capacity of 20000mAh, its weight and volume are exaggerated. There are corresponding instructions on the package, such as pre charging, total output of 6.9 amperes and original Sony cell.
There is a small black label on the upper right corner of the package, indicating that the Sony polymer lithium battery can have a life of 1000 times of cyclic charging.
On the side, the relevant products are used to introduce how many charging times the CP-B20's 20000mAh capacity can provide.
On the back are detailed descriptions of various details.
The CP-B20 has four USB output ports, which can output a total of 6.9 amperes of power, as well as indicators and other small details. It should be noted that the four USB ports of CP-B20 can output 6.9 A in total, but the maximum output of a single USB port is 2.1 A.
In terms of accessories, there is only one manual and a rather simple mirco USB cable
The CP-B20 adopts a metal shell design, and with its large capacity of 20000mAh, its weight reaches 550g, which is terrible in any aspect. It should be noted that CP-B20 is silver white in Japan and black in other regions according to different regions. The metal shell material used by CP-B20 is very comfortable with fine sanding, and has a solid feel.
From the back, it can be seen that the edges of the CP-B20 are rounded and comfortable to hold. There are various detailed data introduction on the back.
Four USB outputs, hard switches, power inputs and indicators are all designed on the same side. The CP-B20 needs to be turned on through the power switch, which may have a slight impact on its use. In addition, I was disappointed that one side of the various switch interfaces was not exquisite enough, which was slightly inconsistent with the metal shell used by CP-B20.
As an exaggerated mobile power supply, the CP-B20 has a capacity of 20000mAh, a weight of 550g and such a huge volume. Although it is not a problem to hold it with one hand, it is still sour and refreshing for a long time. It should also be pointed out that the length of the data line attached with the machine is relatively general. If the CP-B20 is put into the package, it is basically impossible to operate the equipment synchronously.
The corresponding protective sleeve is also included with the purchase, but the tragic workmanship and design do not mean much.
Of course, as a mobile power supply, CP-B20 has a good performance in terms of capacity and workmanship, and its nominal power output is very powerful. We will conduct a detailed test in the future.
