The hardware of the mobile phone industry continues to develop, creating a "good man" who can be charged every day. At the same time, it has also brought about the vigorous development of the mobile power industry. Recently Love to play computer games In the preliminary preparation for the horizontal evaluation of mobile power supply, this TR862 launched by TP-LINK won the collective praise and love of the office.

appearance:

On the package, we can see that TP-LINK positioned the TR862 as a 3G wireless router.

The back describes the main functions and selling points, including support for Unicom 3G system, mobile power, OLED display information, and support for mircoSD card reader functions.

TR862 is packed in drawer style, three of which are TP-LINK trademarks, and the body of this test can be seen by pulling out the remaining side.

The family photo includes TR862 body, USB connection cable, manual and warranty card.

The overall design of TR862 feels like a simple and generous European refrigerator, or a vertical refrigerator. Even with 5200mA and wireless router function, the size is still small. TR862 has an OLED display screen and trademark on the front, supplemented by simple patterns.

The left side is clean, and the right side has power switch, RESET button, SIM card and mirco SD card slot.

The upper and lower parts are mirco USB (power input) and USB (power output) respectively.

On the back is the relevant information. We can see 5200mAh and 1A output. There are also user names, passwords, IP addresses, etc. required by the wireless routing function.

compatibility:

The author selected OPPO Find 5, Huawei Mate, Samsung Note II, iPhone 5, iPad 4 and iPad mini for testing. Although the TR862 message indicates that only 1A output is available, it can be charged for all kinds of popular large screen mobile phones, or for iPad 4 with horrible input requirements. It can be said that there is no fault in compatibility.

Power efficiency:

As a mobile power supply, its main function is charging. In terms of cruise test, the author adopts a more practical method, using OPPO Find 5 to test. The specific evaluation method is: first, fully charge the TR862, and then power down the Find 5 until it automatically shuts down. Turn on the TR862 to charge the Find 5 and turn it on. During the charging process, Find 5 opens the wifi connection without inserting the sim card. Close the screen, check the power regularly and record. It should be noted that the battery of Find 5 is 2500mAh.

TR862 charges Find 5 from 0% to 91% in 1~3 charging, which takes 175 minutes in total. Then automatically shut down and recharge Find 5 when it consumes power. TR862 automatically shuts down after charging Find 5 from 0% to 45% in the second charge, which takes 87 minutes.

The TR862 outputs 3400mAh of electricity in total according to the two times of charging (it should be noted that since the mobile phone charging is not a constant current output and the electricity proportion display error, this value is only for reference), the charging time is similar to the AC charging efficiency.

According to the total power of 5200mAh, the output power of 3400mAh is only 65%, which seems to be a passing grade. However, in the subsequent wireless routing evaluation function, it is found that the TR862 provides the mobile power function after power on, and the wireless routing function is also enabled, Therefore, while outputting 3400mAh, 272min wifi is also provided, which can be said to be quite powerful.

In the future test of mobile power supply, Ioko will use the constant current test method to discharge at a constant current and use a computer record to compare and evaluate the charging capacity of TR862 with other mobile power supplies.

Wireless routing function:

TP-LINK's TR862 not only has mobile power function, but also has 3G wireless router function. What we tested this time is the Unicom WCDMA version, and there is also the Telecom CDMA version for you to choose. One thing to remind you is that the 3G wireless router function of TR862 needs to insert the original SIM card, not the mirco SIM card, and there is no restore card in the package.

Press and hold the power key to turn on the wireless router. It can scan and access directly, and no password is set by default.

Enter the router management interface to further set relevant settings. In the upper right corner are some tips, such as battery surplus, SMS reminder, Internet access, etc.

Through the setup wizard, you can simply set up and complete the Internet settings.

You can also read and write SMS messages through the SMS interface, which is convenient for monitoring traffic.

Through advanced settings, you can further develop and optimize your TR862.

Summary:

The TR862 is the most unpopular among the mobile power sources in the office of iComputer. The TR862 focuses on 3G wireless routers and provides 5200mAh batteries. For such a composite "mobile power" with complete functions, good performance and a price of 370, it is undoubtedly worth recommending. It is also hoped that TP-LINK can introduce firmware updates, and without inserting a SIM card, it will not turn on wifi to provide complete mobile power functions.
