Recently on a business trip, I was taught a lesson. When I packed my luggage, I was still thinking about whether to take the 10000mAh large power supply or a small one the size of lipstick What about the power supply? After a dispute in my mind and a lazy personality, I chose the latter. Later I can imagine that a small battery of several thousand milliamperes is not enough to charge the mobile phone once, The mobile phone without electricity can't even count as a brick. There is no mobile phone for several hours. The time spent by the rogue in the car is indescribable. I regret that there was no choice at that time Take Daye, a large power supply of 10000mAh. You may be curious about this power supply. To be honest, I am also curious about this Chinese name. Let's get together Let's understand first.

Let's first get to know the brand Loca, a designer brand from Hong Kong, which has been dedicated to designing and manufacturing various mobile phone peripherals since 2008 Sex products, designed and produced multi port smart charger, high-speed memory card, smart audio, personalized car charger, mobile power supply, etc. Since 2012, Loca has entered China Market, named as Luke in Chinese, has established a marketing and sales department in line with the Chinese market. Daylight is a power supply product under the company. The word Daylight originally means daytime The meaning of "bright" is poor quality battery. The output of the power bank is too large, and the phone can't stand it. Lucky Day is a new choice for you. It gives you light. One of the reasons is to reject poor quality power supply . The second reason is that it is made of aluminum alloy metal, which is full of light at the first sight. It turns out that both of them choose to see light and hope , hence the name of day. But how does it behave? Let's go on to see.

The package of this power supply adopts a commonly used rectangular box structure, with silver daylight characters on the front and black characters on the bottom of the smart fast charging mobile power supply, showing luxury in a low-key way, The box is generally simple. The side of the box is marked with the characteristics of the product in English. Two ports are output, high temperature protection, and fast charging. The box cover is sealed with a piece of label paper Manufacturer information and common QR code are printed for everyone's attention. Tear off the label, open the box from left to right, and the golden power supply lies quietly in it. This power supply has silver Color, Rose Gold and Champagne Gold can be selected. This one should be Champagne Gold. In addition to the mobile power supply, simple instructions and warranty cards are also provided In order to facilitate charging, a data cable is also provided.

In manufacturing, this power supply is made of anodized aluminum, integrated molding process, surface shot blasting treatment, and its appearance gives a sense of frosting. The overall dimension is 15.8x6.8x6cm The size is opposite to that of the mobile phone. It should be said that it is more suitable for hand holding. The square box design of the power supply body, plus there is no excessive arc chamfer on each side. In fact, it is comfortable to use Poor. The weight is 196.2g. For the 10000mAh power supply, the weight is relatively light, so there is no sense of hand. The two sides of the power supply are sealed by plastic injection molding, The aluminum panel on the side has a slight burr feeling when touched lightly by hand, and the workmanship needs to be further strengthened. In this age of beauty, the beautiful appearance can gain more favor.

The safety and reliability of power charging is the most concerned topic. A good power supply cell is the key. This power supply uses Samsung imported polymer cell, Big brand with guaranteed safety. In addition to intelligent current charging control, the charging current can be adjusted intelligently according to the equipment, and the output current varies between 0.5A-2.4A Intelligent selection of better protection charging equipment, and the surface of aluminum oxide shell also provides better security for charging and cooling. The power supply provides 2-way output USB It can charge two devices at the same time. Four LED lights remind you of the power. When charging at night, it feels a bit blinking. It would be better if the brightness could be reduced.

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 reduction of instruments For errors caused by external reasons such as data lines, we took another power supply for comparison test. Prepare a current and voltage detection instrument, 1A, 2A One aging resistor and one 5200mAh power supply for comparison. First of all, we choose a resistance of 1A, and use two mobile power supplies to discharge them respectively Current 0.95A, output voltage 5.01V. The output current of the other power supply is 0.99A, and the output voltage is 5.17V. Considering the error of instrument accuracy and resistance, the two are calculated and compared Approach.

For the second time, we selected a resistance of 2A, and used two mobile power supplies to discharge them again. The output current in the day was 1.8A, and the output voltage was 4.8V. Another power supply The output current is 1.9A and the output voltage is 5.03V. After comparison, it is not difficult to find that the daytime current and voltage are slightly small. Is it true that in order to protect the equipment and achieve better balance, The result of careful optimization of power supply scheme.

For further verification, we asked R5 mobile phones that charge for five minutes and talk for one hour to conduct charging test. In order to obtain more reasonable time, we directly took The stopwatch on the mobile phone is used for timing. We select the 95% - 96% charging period as a timing period, and charge the charge period in three ways . Since the mobile phone charger defaults to normal charging during this period, there is no flash charging. Mobile phone charger, power from 95% to 96%, time 01:56.17, The other mobile power supply has a power consumption of 95% - 96% and a time of 01:54.87. The daytime mobile power supply has a power consumption of 95% - 96% and a time of 01:44.51. By comparison, the daytime charging In terms of electric speed, it has obvious advantages.

Conclusion: This power supply has large capacity and can charge two devices at the same time. It has obvious advantages in terms of moderate charging, which is worth affirming, but the workmanship needs further improvement We are looking forward to another 2000mAh Sichuan crowdfunding in JD, which will bring different highlights.
