With the rapid development of mobile digital products, the contradiction of high power consumption but no AC power to supplement power emerged, so mobile power came into being. All of a sudden, all kinds of mobile power were overwhelming, including some low-quality products flooding the market, including crude manufacturers, those with false capacity standards, and even more people used sediment cement weights to deceive consumers, The news of the explosion of mobile power is often heard. A few days ago, it was initiated by Lei Feng.com Romance Polymos10 mobile power supply We are lucky to get the qualification for the trial evaluation activity. Thank Lei Feng.com and Luolishi Technology Co., Ltd. for providing mobile power!

A piece of printing paper is pasted on the hard paper shell of the following package of the product, which says "paranoia, extreme never stop", fully demonstrating the enterprising spirit of Luxi

"Lithium polymer mobile power supply" is marked on the side, so the product can be small, thin and light. In addition, the beautiful shape design makes it easy for users to hold and very portable

The back is the product parameter information

Open the box, and a small and beautiful mobile power supply will appear in front of you

Attached micro USB One charging line and one manual.

Standard charging line

White upper panel, with A circle and“ ROMOSS ”There are four indicator lights on the lower right corner, each of which represents 25% of the power. The lower box body is light gray, and the whole body is frosted. It has a delicate feel and is not easy to slip off. The semicircular arc design is easy to grasp and very user-friendly

There is a wake-up function button on the side. Press this button once to charge the digital device, and it will enter the sleep state when charging is not required

There are three interfaces on the top, namely Micro USB Input interface and dual USB Output interface, two USB output interfaces are distinguished by one lightning symbol and two lightning symbols respectively. One lightning symbol interface can provide 5V1A power supply, the two lightning symbols are 5V2.1A, and the total current of the two interfaces at the same time cannot be greater than 2.1A

There are detailed instructions on the back of the power supply for users to consult at any time

It looks beautiful

Now let's do a test. First discharge the battery, and then charge it with 2A power supply. The current can reach 1.63A. The charging current is very satisfactory. It is estimated that it will be fully charged in more than 6 hours

After 6 hours and 15 minutes, the charging is completed, and 9819 mah is displayed, indicating that the battery has no false label

All four orange indicators are on

Now let's do the discharge test again to see the load capacity. This is the no-load voltage of 5.10V

First discharge with 0.5A, and the voltage drops to 4.97V

Continue to increase the current to 1A and the voltage drop to 4.93A

Then increase it to 1.5A, and the voltage drops to 4.87V

Increase it to 2A, which is already the rated current, and the voltage drops to 4.82V

Simply increase it again. Carry out overload test. When it reaches 2.5A, the voltage drops to 4.77V, which is the limit. If it takes a short time, it will output protection

Now let's see what the effect of charging the mobile phone will be. First, let's see that the output no-load voltage is 5.09V

This is to charge Xiaomi 4. The current is 0.48A and the voltage is 4.97V

This is to charge the iPadmini. The current is 0.64A and the voltage is 4.94V

Conclusion: Through the above experiments, it is not difficult to find that the Romos mobile power supply has a good performance in terms of appearance, load capacity and capacity, especially the overload capacity is amazing. If it can be further improved in terms of fast charging, it will be more perfect. I hope that Romance can keep forging ahead and make the best of mobile power!
