There are many brands of mobile power, and the quality is good and bad. The author has used several brands of products in recent years, most of which are plastic shells, and some are metal shells. Thanks to Lei Feng for using it for the first time All aluminum alloy mobile power supply.

Beaver Moment Mobile Power (customized version of Lei Feng.com) is heavy and powerful. The packing box is small and simple. The front shows the shape of the mobile power supply with a cyan pattern, and the back shows the product introduction Shao (equipped with English version) and parameter information, the lower right corner is Lei Feng's trial logo, and the side is printed with the product name - Beaver Yike Mobile Power ， From the side thickness, we can judge that the product is very thin.

Open the package and take out the mobile power supply and instructions. They are really simple. Even the charging wire is not standard. Personally, I think it's a bit bad because the inner and outer packing boxes are thin and have limited force, and the packing box capacity during transportation It is easy to be compressed and deformed, which affects the appearance (when the author received the goods, the outer packing box had been deformed, but the mobile power supply is an all aluminum alloy shell, without any injury).

The detailed parameters of Beaver Moment can be learned from the official website and the manual. One of the highlights of Beaver Moment is the fast charging function, that is, use a compatible MacBook power adapter to quickly charge the mobile power for about 1.2 hours（ The author is not a fruit powder, and there is no corresponding accessory, so this function cannot be tested). If you use an ordinary Micro USB charging cable, it will take about 5.5 hours to fully charge it. Beaver is thinner than 10000mah Annengtai 590TB, all aluminum alloy The shell adopts the same surface texture and sandblasting technology as Macbook. Under the reflection of light, it looks tall. It is not only wear-resistant and corrosion resistant, but also has no trouble of fading. There are 4 blue LED lights in the lower right corner of the front, corresponding to Power display. Shake it to display the remaining power. There is a round hole in the upper left corner, which can be hung on the backpack when traveling, so it is convenient to charge the mobile phone. On the back is the customized logo and product information of Lei Feng. com, which is laser etched without losing words or color. All interfaces are on the lower side, from left to right are quick charging interfaces 、 USB output interface, Micro USB slow charging interface. Beaver and OPPO R7s will not feel bulky when they are held together. They are both metal shells and full of sense of technology.

Use beaver to charge the mobile phone at a moment. At 20:07, use mobile power (75% of the remaining power) to charge Nubia Z5S (22% of the remaining power). Use USB tester to monitor the whole process. Detailed data See the table below. Since the mobile phone is not powered off for charging, and the data and WIFI are turned on, the background resident program, and there are voice calls, video calls and other application operations, it is difficult to count the power consumption. Time period 21:33-22:17 The data of 22:17-22:25 is relatively referential, and the time period of 21:33-22:17 shows that the 84% power conversion rate is good. We can also see from the statistical table that the power of mobile phones is gradually When fully charged, the voltage is basically unchanged, and the output current automatically decreases slowly.

After the beaver's built-in power is consumed, that is, the led lamp does not light up and there is no power output, the charging test is carried out. At 01:14 of the time point, the charging starts. At this time, the input voltage is 5.12V, the current is 0.73A, and the time point is 07:45 Four blue LED lights are on. At this time, the input voltage is 5.18V, the current is 0.16A, and the power input is 5448mah. It can be judged that the power is basically full. Since it is charging at night, the total charging time cannot be counted.

Personal summary

Advantages: 1. The all aluminum alloy metal shell is colorfast, wear-resistant, corrosion-resistant, and has strong heat dissipation (the current indoor temperature is 13 degrees, the metal shell feels cold, and no charge/discharge temperature test is conducted); 2. Compatible with MacBook The power adapter quickly fills the mobile power supply in about 1.2 hours; 3. The conversion rate of charging and discharging power supply is good; Disadvantages: 1. When charging, the led light will not be on, nor will it be on when shaking, and the remaining power cannot be checked; 2、 The material of the packaging box needs to be improved, which is not very symmetrical with the high-end feeling brought by the metal shell;

In a word, Beaver Moment Mobile Power Supply is a metal power supply. Lei Feng tried a customized mobile power supply with a mobile phone with a metal shell to make it look tall. It can also be used as a private customized mobile power supply for enterprises High grade gifts for employees' welfare or business dealings.
