Large screen, high configuration and super long standby have always been the pursuit of mobile phone development in recent years. The hardware configuration of manufacturers has been constantly updated. Large screen is a major consumer of energy. In addition, for the sake of mobile phone security All in all, the battery problem of mobile phones has been puzzling the development of mobile phones, and mobile phones have become the standard configuration once charged every day. Fortunately, the rapid development of mobile power in recent years has made up for smart phones The defect of the machine and the strong market demand naturally led to the prosperity of the mobile power market, and the quality of the domestic power market products is uneven. A good product naturally Can win the market. Today, we bring you a value for money intelligent charging power supply. Let's feel it together.

The package of this power supply is standard. The yellow kraft paper outer packaging box should be more suitable to say it should be a universal packaging box. The product label can be sealed, and more costs should be spent on The process of the power supply and the design and development of the power supply, the front label of the outer package is marked with the brand name and product concept, paranoid, extreme and never stop, and the pursuit of a perfect brand It is easy to produce Niubian products, and this power supply should not disappoint people. The back label indicates the product specifications and some relevant product information. The packing list is marked in detail For the items in the box, the OEM and executive standards are marked on the bottom. Naturally, it is a qualified power supply. Compulsory product certification is indispensable, and the product name is properly pasted on the box label In the middle of the sign, polymos 10 lithium polymer mobile power supply.

Open the package, this power supply is also relatively simple in terms of accessories. In addition to the power supply body and the manual, a 5Ocm data charging cable is randomly equipped The rise of charging methods is becoming more and more diversified. This length is enough for use. This power supply is available in sky blue, pink and white The size of 142x65x15mm and the weight of 204g make this power supply more convenient to carry compared with similar large blocks with a capacity of 10000mAh. 142mm wide with arc chamfer design In addition to careful polishing, even girls' small hands can be comfortably mastered. The front of the theme of the power supply is marked with the product logo, the right side is marked with the LED light for power display, and the back is detailed The product details are marked again.

For a good power supply, the cell is the key. Lithium polymer, with large capacity and stable performance, is a good choice. This power supply also provides dual port output There is a difference between the above two. They are 5v 1A and 5v 2.1A outputs. In actual use, there is no big difference. With the demand of power supply, more and more charging power supplies with voltage and current display More, and this power supply provides LED light power display. When one light is on, the power is 0-25%; when two lights are on, the power is 25-50%; when three lights are on, the power is 50-75%, The power of the four lights is 75-100%. With such a small tip, it is not necessary to take a mobile power supply without charging on business trips and make a joke.

In order to understand the performance of this power supply in more detail, we used current and voltage detectors and variable resistors for further detection. Considering the external of instruments, data lines, etc For the error caused by the reason and the impact of multi port output, we will prepare another mobile phone to participate in the test. Prepare a current and voltage detector, 1A and 2A aging resistance First, we use current and voltage detection instruments to test the no-load of this power supply. The standby voltage of the two output ports is 5.12v. Considering the accuracy error of the instrument, The voltage is a little high.

Next, we select the standard aging resistance of 2A to conduct a discharge test on this power supply, and test the upper and lower output USB ports respectively. The upper output current is 1.77A, and the output voltage is 1.77A 4.85V； The output current of the lower port is 1.76A, and the output voltage is 4.85V. Compared with other power supplies, the current and voltage of this output value are a little small. Maybe it is better to protect the equipment Balance is achieved and the power scheme is carefully optimized.

In order to further experience the performance of this power supply, we tested the dual output full load of this power supply. One output port is inserted into the mobile phone for charging, and the other port is still 1A 2A aging resistance shall be tested separately. First, 1A aging resistance was selected, and two ports were exchanged for testing. The output current of the upper port was 0.92A, and the output voltage was 4.91V; Lower output The current is 0.91A, and the output voltage is 4.86V. The difference between the two outputs is not significant, which seems to have nothing to do with the 1A and 2A ports marked in the manual.

Then we selected 2A aging resistance, and then exchanged two ports for testing, the upper port output current is 1.78A, and the output voltage is 4.80V; Lower output current 1.74A, output The voltage is 4.78V. Compared with the single port output above, it is not difficult to find that the double port output is almost the same as the single port output. Such output current and voltage are still positive Of. This 10000mAh large battery has a conversion rate of 85% and a charging efficiency of 88%. Due to equipment limitations, it was not tested. For a 3000mAh battery capacity This mobile phone is recharged for more than two times. It is more than enough to carry it when you go out in case of accidents.

Conclusion: This power supply has large capacity, small shape, and arc chamfer design. In addition to careful polishing, it is comfortable to master, easy to carry, and multi port plus intelligent charging mode for free matching Yes, it can charge two devices at the same time, which is the best choice for home and going out.
