preface

Mobile phones play a more and more important role in people's life. Both work and life need the assistance of mobile phones, but the resulting problems also follow. The first problem is the power of the mobile phone. As the mobile phone becomes thinner and thinner, the capacity of the battery seriously restricts the use of the power of the mobile phone. So the hardworking and intelligent working people invented the mobile power supply. Today, we bring you a small mobile power supply with sufficient energy - quarter moment mobile power supply.

Unpacking

The package of the quarter mobile power supply is very simple and clear, with only "quarter moment" written in the lower left corner. The main color is elegant white, which gives people a sense of grandeur. The packaging is very rigorous.

Open the package, and our hero will appear. The one evaluated by the author is pure white. The small power supply is wrapped in a warm black sponge, which looks very enjoyable.

A data cable was also provided with the machine, but the miniUSB terminal is dedicated to Apple. The charging line is relatively short, only about 30cm long, and the alloy connector is very solid. TPE material and durability should be reliable.

The size of the quarter is very small. It looks about 96 * 43 * 23mm and weighs about 30g. It is very portable.

Interface:

The quarter mobile power supply is equipped with a TYPE-C interface, which has a more efficient transmission rate, up to 5A. This is also the development trend of mobile phone interface in the future. Quarter's advanced design of TYPE-C interface is still very impressive.

The four LED lights at the bottom are used to display the power. There is no external key design, and the switch mode is automatically recognized.

The bottom of the mobile power supply indicates that the product model is X1

Rated capacity: 3.7V/5000mAh

Input: 5V/2A

Output: 5V/2A

use

The author used the ancestral treasure to test the power. According to the previous parameters, the output power of the power supply is 5V/2A, and the capacity is 5000mA. Users who travel frequently and take the gray plane can take it with confidence, because the CAAC stipulates that mobile power supply exceeding 100Wh will be prohibited to take on the plane.

5V * (5000mAh/1000)=25Wh, so you can safely take the plane with you, and you don't have to worry about the security check uncle's trouble.

Next, let's take a look at the actual test charging curve. When charging, the power supply is mostly stable at about 5.2V and 0.34A. Trickle charging time is very short, and the heat dissipation during charging is also very ideal.

Next, test the output capacity of the power supply. It is surprising to find that the charging effect is maintained at 5.1~5.2V throughout the whole process, which is very stable. This can better protect the operation of the battery and extend the life of the battery.

summary

After the author's test and nearly half a month's use, this quarter mobile power supply is "as stable as a dog" in terms of charging. The actual output voltage is basically higher than 5.1V, which can greatly shorten the charging time. The stability of the voltage can also better protect the cell phone battery and extend the life of the cell phone battery. The appearance is also very fashionable. The compact figure is easy to carry, and the fever is not obvious. In general, it is a mobile power supply that can be used with confidence.
