Large capacity mobile power is undoubtedly the best match for WeChat and Weibo controllers using large screen mobile phones. If a large capacity mobile power only highlights its large capacity and ignores its weight, it will not be favored by users. The thin and light models with the same capacity but different volumes and weights are naturally more attractive. Romance polymos 10 The mobile power supply adopts a new lithium polymer cell, which meets the demand in terms of energy and weight.

Romance polymos 10 The corrugated paper box commonly used in the industry is used for external packaging, and then a self-adhesive paper label is pasted to make a description of Romance polymos 10 The detailed parameter information of is described and the packaging box is sealed.

Those who have used the Romance mobile power supply are familiar with the slogan "paranoia, extreme never stop"

Model: PB10, rated energy 37Wh Capacity is 10000mAh, input 5V2.1A , output 5V2.1A 、 5V1A , the maximum output is 2.1A . via FC/CE authentication

The "Treasure" Romance polymos 10 , hope the performance remains the same

Open the package to directly see the mobile power supply host and pack it with anti-static bags. All items inside are as follows: power supply host * 1, product instructions *1 (including warranty card) Micro usb data line *1 . There are no other accessories in the package, and there is no matching power adapter. You need to equip it yourself. This is not a problem 5V We believe that there are several chargers, which are common with mobile phone power adapter

Romance polymos 10 The mobile power supply shell is composed of white upper cover and light gray bottom shell. The surface has been sanded and PVC environmental protection shell is used, showing a simple design style. The new polymer core is adopted, and the three parameters are 142*65*16.6mm, Compared with similar products eighteen thousand six hundred and fifty The cell is much thinner and much lighter in weight. Overall volume and one five Inch mobile phones are equivalent.

Romance polymos 10 The back of the mobile power supply is marked with relevant parameter information, certification information and precautions

Host interface: Micro usb * 1/2.1A input, two Standard USB Output, one of which is 1A Output, the other port is 2.1A Output, and output identification is made below each output interface. One lightning indicator is 1A , two lightning signs are 2.1A Output, so there is no insertion error.

As can be seen from the above figure, Romance polymos 10 The mobile power supply has been rounded at every corner to improve the hand feel, and even if the phone is stacked with the power supply, there will be no scratch

A physical entity button is designed on the side of the fuselage to activate the output and check the power consumption. When the button is pressed, four buttons on the panel LED The power indicator lights up, and the power represented by each indicator is 25%

Seven thousand cats are produced, which is the province

Romance polymos 10 The mobile power supply is currently priced at 79 yuan in the official flagship store, but it has been taken off the shelves

Weighing by high-precision electronic scale, ROMES polymos 10 The actual weight of the mobile power supply is 229.92g, which is quite light and easy to carry

Performance test:

A mobile power supply with a good appearance and a high-performance battery cell can't just talk about it, but also needs to be evaluated by its quality level. It was originally intended to use programmable constant current electronic load equipment to polymos 10 The mobile power supply is tested. Now, use the ZB206+discharge tester to test the ROMES polymos 10 Carry out a simulated discharge test on the mobile power supply, and directly conduct the maximum 2A discharge to see its output energy

Romance polymos 10 No load voltage of mobile power supply is 5.1V

Use 2A cement resistor as load, and keep the voltage at 4.9V , current and can 1.82A

adopt ZB206+ The discharge tester fixes the output 2A To discharge

After more than 4 hours of waiting for discharge, ZB206+ The discharge tester displays a voltage of 4.83V , I can accept it

The final Romance polymos 10 The mobile power supply is discharged under the discharge test of 2A 6127mAh Capacity of

The final energy released is 29.41Wh

Through the above 2A discharge test, in terms of output efficiency, the energy (capacity) obtained from the above simulated discharge energy is taken as the effective reference value, and then the charging times can be obtained as a reference after conversion in combination with the battery energy (capacity) of mobile devices. In the above 5V2A analog discharge test, the energy obtained is 29.41Wh. Divided by the rated energy of the nominal value 37Wh, the final most effective conversion rate is 79.4%. Although this result is not a big surprise, it will not be worse.

Next, through programmable constant current electronic load equipment polymos 10 Carry out 1A discharge test on the mobile power supply to see the result.

Let's first look at conventional stepping, using programmable constant current electronic load to thirty Seconds 0.1A In order to increase the load level step by step from low to high, draw a curve icon to visually see Roman Shi polymos 10 Load conditions of mobile power supply at all levels.

Connect the constant step curve of programmable constant current electronic load: the starting voltage is 5.12V, and the ending voltage is 4.82V. The nominal rated maximum load capacity is 2.1A, while the actual tested maximum load capacity is 2.5A. If it exceeds 2.5A, the output will be automatically protected and closed. After the current reaches 2.5A, the voltage remains at 4.8V, and then drops rapidly to 0 after protection, so the maximum actual available current is 2.5A, and the voltage fluctuation is very stable without burrs

use 5V1A The output capacity test of constant current discharge shows that the total discharge capacity is 6529mAh, and the energy is 32.44Wh. The average voltage during the whole discharge process is 4.97V. According to the 37Wh marked on the nameplate information of its parameters, the conversion efficiency after conversion is 87.67%

During the whole constant current discharge, the voltage is kept very stable

Through output capacity test, ROMES polymos 10 Mobile power can be Apple iPhone 6s (1715mAh) Rechargeable times: about three point eight And Xiaomi five Mobile phone（ 3000mAh) The number of charges is about two point one seven second

The advantage of large capacity mobile power supply is that it does not need to charge the machine frequently, but it also takes a long time to charge the machine when the power is used up. Why do some friends say that the charging time for this machine is too long? Maybe it is due to the wrong charger specification. At the same time, they also have requirements for the data cable. Some data cables are too poor in material and have too large line resistance, which also causes slow charging. Romance polymos 10 The mobile power supply supports 5V2A output. This time, a high-quality power adapter is specially selected as the Romance polymos 10 The mobile power supply is used for charging test. It uses its own data line (compared with other data lines, the efficiency of its own original data line is much higher than that of other common data lines) to charge almost full load, and finally, it is used for Romance polymos 10 The mobile power supply shall be fully charged for 6.5 hours.

Generally speaking, Romance polymos 10 The performance of mobile power supply is good, and it is much easier to use the polymer core with higher safety and outstanding weight.
