The name Zimi may not be familiar to many people, but it is well-known when it comes to Xiaomi Mobile Power, and Zimi is the OEM of Xiaomi Mobile Power. After launching several mobile power supplies with different capacities for Xiaomi, Zimi officially released its first brand product, namely P810.

Compared with the publicity of Xiaomi Mobile Power, the debut of Zimi P810 was very quiet, which naturally has a great relationship with its brand. As far as the appearance design is concerned, there is nothing special about the purple rice P810. The pure white plus the wavy stripe design on the surface is enough to finish the sentence.

The upper left corner is the purple rice logo, in which the design of MI is basically the same as that of Xiaomi Technology, highlighting its role as a link in Xiaomi's ecological chain.

On the side, there are abnormal detailed related parameters. There are battery capacity parameters on the left, which are 10000mAh at 3.7V and 6600mAh at 5.1V. The nominal conversion rate is more than 90% at 1A output. The telecommunication standard value of Zimi P810 is 10000mAh, the minimum value is 9880mAh, and the rated power is 37Wh and 36.55Wh respectively.

According to the design of relevant parameters, the standard output power of Zimi P810 is 37Wh, and the minimum output power is 36.55Wh. Zimi indicates that its output is 1A, and the conversion rate is more than 90%, that is, the output of Zimi P810 is at least 32.895Wh or more, which will be verified in the subsequent actual test.

Purple rice P810 has only one output port, and the maximum output current is 2.1A. Four white LEDs are used for light on display, and the hard switch is used. Comparatively speaking, the single output of Zimi P810 may be inconvenient in some use scenarios compared with the dual output of competitors.

The actual test uses a DC electronic load meter to test and conduct a simulated discharge test. The test items include 5V/1A and 5V/2A, measure the actual voltage and actual output power respectively, and calculate the conversion rate according to the formula "mobile power conversion efficiency=actual output power/nominal output power=(actual output capacity * average discharge voltage)/(actual cell capacity * 3.7V)".

According to the test of DC electronic load meter, under 5V/1A output, the actual discharge energy of Zimi P810 is 32.41Wh, and the average output voltage is 4.97V. From the discharge curve, the voltage fluctuation of purple rice P810 is very stable, and there is no significant voltage drop in the later stage of discharge. The output quality is quite excellent. According to this calculation, the conversion efficiency of purple rice P810 under 1A output is 87.59%, which is relatively excellent.

Although the conversion rate of purple rice P810 reaches 87.59% under 5V/1A, it is an excellent result, but it is a certain distance from its claim that it will get more than 90%.

According to the test of DC electronic load meter, under 5V/2A output, the actual discharge energy of Zimi P810 is 30.50Wh, and the average output voltage is 4.9V. From the discharge curve, the voltage fluctuation of purple rice P810 is very stable, and there is no significant voltage drop in the later stage of discharge. The output quality is quite excellent. According to this calculation, the conversion efficiency of purple rice P810 under 2A output condition is 82.43%, which is relatively excellent.

Zimi P810 is a very "standard" mobile power supply. In fact, it is aimed at the pure functional area of mobile power supply in all aspects, without making efforts on various lighting effects, shape design and intelligence. It focuses on the power conversion rate, which involves the internal circuit design and master IC control, and also has high technology and requirements for manufacturers.

In terms of actual test, under 5V/1A output environment, the actual conversion efficiency of Zimi P810 is; In the 5V/2A output environment, the actual conversion efficiency is 82.43%, and the overall performance is excellent. Compared with similar products, the purple rice P810 is inferior in that its single port output is inconvenient to use in some scenarios. Of course, in general, the purple rice P810 worth 99 yuan is worth recommending under the condition of high conversion rate.
