With the popularity of digital products such as smart phones and tablets, battery life has always been an important factor affecting the user experience, and it is also a headache for manufacturers when designing products. It is really difficult to choose between how to balance the two contradictions of battery life and weight, in order to make products lighter and thinner, and also to meet certain battery life. Today, the battery technology has not yet made a major breakthrough, and the emergence of mobile power has become logical, becoming the first choice to solve the problem of mobile phone endurance. The author got the chance to try out this "Romance Polymos10 Mobile Power Supply" on Lei Feng.com, and then he will share the experience with you briefly.

"Romance" is a brand that many people have heard of. It is a big brand in the mobile power industry and has a good reputation. The products are packed in ordinary cartons, which are energy-saving and environmentally friendly. The blue label is pasted on the surface, which needs to be torn off when unpacking, indicating that it is a new product with original packaging and unopened. The company's product philosophy: "paranoia, extreme never stop" is very eye-catching, which makes people look forward to the products inside. There are detailed parameters of the product on the back.

Unpacking the box, there is a mobile power supply, a power cord and instructions, and the standard configuration of similar products.

The complimentary charging line is of solid workmanship, with the "ROMOS S" sign on the connector, which is about 50cm short, basically enough.

The front of the Romance Polymos 10 mobile power supply is pure white, with the product logo in the middle and the power indicator in the lower right corner. The other surfaces are light gray, and there is a unique entity key on the side. After pressing it, the power indicator will light up to show the remaining power. The lighting effect of the power indicator is well designed. It shows a light orange on a translucent white background, which is very beautiful. It should be noted that when you use the mobile power to charge your phone or pad, you need to press the power button once to start charging.

This Romance mobile power supply adopts a large number of rounded corners, which are smooth and round, and will not separate hands at all. High appearance and good hand feel are my most intuitive feelings about this power supply.

In terms of interface, Romos Polymos10 provides one power input port and two power input ports. The middle lightning sign is 5V@1A The 5V2.1A output port is next to the two lightning signs. It can output from one port or two ports at the same time. Single port output ensures fast charging, and dual port output can intelligently distribute current, but the total current will not exceed 2.1A.

Actual charging experience: Romance Polymos10 support [email protected] It's a pity that the author doesn't have a 2.1A charging head on hand, but only one Samsung original 2A charging head, which can basically explain the problem. Through many tests, it takes 6.5-7 hours for the mobile power supply to fully charge. It takes about 3.5-4 hours to charge Sony Z3 with the 2.1A output port of the Polymos10. The battery capacity of the Z3 is 3100mAh. While charging Sony Z3 directly with the 2A charging head takes 3-3.5 hours.

Conclusion: The size and charging/discharging speed of the 10000mAh Romex mobile power supply are satisfactory, and it has no advantages over other brands of mobile power supply. Its biggest advantage lies in its bright appearance and comfortable feel. As for the capacity of mobile power supply, the author thinks 10000mAh is just good. 15000mAh or even 20000mAh mobile power supplies are only suitable for long-distance travel, while 5000mAh and below mobile power supplies lack a sense of security. It is recommended to purchase 10000mAh mobile power supplies for daily use.
