With the popularity of smart phones and the development of mobile Internet in recent years, people rely more and more on mobile phones. Although in terms of functionality, smart phones have tended to be perfect and have almost become the final form of smart terminals at this stage, the endurance ability has become a bottleneck that has to be broken between the pursuit of lightweight portability and long-term durability of smart phones. As a result, a prosperous mobile power market has emerged. Thanks to Lei Fengzhong for the Romance mobile power supply provided by the test company, let's see whether the "paranoia" in the mobile power supply is like it said, "never stop on the road of pursuing perfection."

The product is packed with kraft paper, which is popular in digital products nowadays. The outer and inner layers are relatively simple. Although environmentally friendly, it is difficult to impress consumers. Personally, I believe that packaging is the first appearance of products, and packaging innovation should also be a direction of striving for perfection.

The quality of the data cable included in the package is good. The cable is thick and has strong toughness. The interface at both ends is very tight.

The whole mobile power supply is made of plastic, with white surface panel and light gray body below. The first impression is that it is very beautiful. The appearance design is clean and neat, without too many unnecessary decorations. The four corners and side radians of the fuselage are in place, and there is no uncomfortable feeling in the hand. The small body is stuffed with 10000mAh battery capacity, and the polymer cell is more efficient and safer.

The mobile power supply is equipped with two USB charging ports, which support 5V/2.1A and 5V/1A charging specifications. However, if the two charging ports work at the same time, the total output is also 5V/2.1A. This design enables the mobile power supply to charge two devices at the same time when the power is constant, and also ensures the high efficiency of charging a single device to a certain extent.

The back of the mobile power supply is marked with product information, so there is nothing special about it. Personally, I feel that there are too many information labels, which are not concise and clear enough.

There is a button on the side of the mobile power supply. Press it to start the power supply. At the same time, the indicator on the front shows the current remaining power. I have to say that the design of this hidden indicator light is very good. The light source is hidden under the white panel, and only when it is lit can I see the mystery.

In the actual use process, the charging speed is not too big. The 5V/2.1A charging port is used for charging, and the actual charging speed is slightly lower than that of the 5V/2A charger. The Huawei P8 mobile phone used in the test has a battery capacity of 2600 mAh. It took nearly 4 hours to charge from 0% to 100%, and it can be fully charged in about 3 hours when charging with a 5V/2A charger. It takes nearly 7 hours to charge the mobile power supply with a 5V/2A charger.

In general, Ramos mobile power is a standard product, which can really solve the pain points of many users during the period when mobile phone battery technology encounters bottlenecks. However, there are many mobile power products on the market, how can they stand out from the crowd? Personally, I think the first thing is the appearance and workmanship. The big and ugly mobile power supply will not be liked by anyone; The second is the efficiency of conversion and the speed of charging. If the polymer cell is used and can also support the quick charge technology, then this mobile power supply should be very popular; The last thing is the battery capacity. In my opinion, mobile power supplies above 20000mAh are meaningless unless there is a special need, because the mobile power supply book exists for emergencies. It is sufficient to quickly replenish power for mobile phones at critical moments. If portability is sacrificed for the unlimited expansion of battery capacity, it is putting the cart before the horse. Therefore, according to this standard, the Romance mobile power supply in my hand can only be regarded as satisfactory and barely qualified. There are not too many highlights and slots. I can use it all the time, but it can't arouse my desire to purchase it actively. In my opinion, this "paranoid" is obviously not extreme enough.
