Out of the box
This time, I saw the “value tape†tape. I suddenly felt a lot of excitement, and this time it was Zhang Aunt’s box.
Mobile phone pixels are not good. This trademark
This tape
Then open

What surprised me most was the Toshiba 16G memory card. I didn't say anything about it. The details were very good.
To a few pictures of the United States and the United States
This picture is myself drunk
This is also decent
Small memory card, very warm heart
Still wide, outdoor finish.
Two tapes

Top close-up, shockingly written 5500

Side gilding
This design is still very user-friendly

The bright golden color, why do I say Sao Liang?
Take a shower and wait for you
There is still content below
Manual, charging line, mobile power
There is also a set of sets
The quality of the line is still pretty good
Pig foot closeup
The pixel is dregs oh, can't see clearly
From left to right, it is TF card slot, charging port, USB interface, and power indicator.
Come to a few outdoor maps
parameter
Screenshot of the official website, the size is mainly in the thickness, 9.33 mm, or very thin.
Do not look at the small capacity here, it will give you a slow interpretation of why only 5500 mA. Here to pay attention to the battery type, lithium ion polymer battery. The following is a special introduction to the battery charging problem.
At present, the main popular charging batteries in the market are mainly divided into two types (regular manufacturers): 18650 electromagnetic batteries and polymer batteries.
This is a 18650 cell, this cell is a little lower cost than the polymer cell, so most of the market use this cell; 18650 lithium battery, cycle life of about 300 times, low safety performance, anti-overcharge Poor performance, with more than 2,600 batteries in a single battery, and 4 meters for a certain meter, which is exactly 10400 mA. But here is scalar, not actual electricity.
Cool energy dismantling the interior, using polymer batteries.
Polymer batteries have no shape restrictions, so some of the thinner mobile power supplies in the market use polymer batteries, including this, which is thin. The polymer cores have reached a life cycle of 500 cycles and are not susceptible to explosion and have a high safety factor.
After introducing the batteries, there is one more issue: electromagnetic capacity. The above said that a certain 10400 milliamperes of electromagnetic, after testing (professionals) that 10400 mA through the conversion rate after only 6,000 mA, the actual conversion rate of less than 70%. Conversion rate, which is related to your charging frequency, of course, the higher the better, 89% is the bottleneck of the industry. So do not believe how many mA above the standard, useless, electromagnetic current retractable flow as shown below.
Every time you take a process, you lose power. It's just a matter of how much you lose.
Continue below parameters
Here this product has unique features, app, TF card support, multi-system support.
Made of aluminum alloy.
These are app functions, which will be introduced later.
Features
If the function is introduced, it is app. Here I start by inserting power.
I am also drunk in this map. There is no way to capture screenshots. The first time you insert it here will prompt you to actually download the software.
Click to view into the browser, just click to download just fine. This design is still very convenient, much better than downloading
After downloading the installation, and then prompt the connection problem, select OK on the line.
Into this way, oh, but here is whether to switch to maintenance mode.
In order to save space on the map, this is the main interface, the upper half shows the power and TF card capacity. The lower part shows four functions, which are described below.
The top can be switched TF file and mobile phone file, the default TF file, there are three little dots in the upper left corner, can edit and create a new folder after the point is opened (truncate to map, so talk about it). Below the TF file there is a backup file button, click to see.
Click on the backup to pop up four types, select the video pop-up right, select the video you want to backup click on the backup in the lower right corner.
The following battery experts, this is also the characteristics of this product.
Here are also two tabs, but below, let's look at the battery information. The display is relatively complete, and the temperature and voltage are quite detailed. The above check button can update the following data.
Here is where the charge mode is switched. It is recommended to maintain the battery in the maintenance mode if you are not in a hurry to charge (although I do not know it). Then click on the top right corner.
Isn't that what I don't understand? Well, take a serious look.
Look at the backup below
Backup here can backup SMS and call records, right click to start backup, click the button below to start backup 
Prompt whether to confirm, confirm right after the backup is successful. You can click on the selection in the upper right corner to delete and other operations. Of course, the backup is for recovery.
Then look at the all-round browser.
You can search, the following is classified into three: video, music, network disk. Click the download icon in the upper right corner to enter the right figure. The right figure is divided into two states, downloading and completed.
The left figure is the download completion list, click on the right top of the edit appears right figure, technology to edit and delete. Click on the concert to play directly on the left. This is a built-in music player. There is no built-in video player.
The left figure is the icon in the upper left corner of the starting page. There are several options on the diagram.
Left for feedback, right for setting, click on the format SD card pop-up prompt.
to sum up
advantage:
1, battery maintenance function
2, support for TF expansion
3, thin and stylish appearance
4, app features
Disadvantages:
1. Undoubtedly high prices
2, usb jack is difficult to insert seems to be easy to feel bad
There is also a suggestion here that I would like to say that the problem of reading TF card can be directly replaced by Bluetooth. This can also be shared. If I just want to read the contents, then the line is a burden, although I can read it. Charge when you take things. On the whole, it is still very good, regardless of factors such as workmanship, performance, and security, it is still relatively comprehensive. Finally, thank you very much, this time the public test is here, thank you for reading.
