10 Best USB Testers from Aliexpress

Have you ever faced a situation when charging your phone with two different chargers, you can clearly see the difference in the time taken to fully charge the battery? It seems that the wires are similar in appearance, and the adapters do not differ visually, but through the first, the phone is fully charged in two hours, and through the second in four. Or another example: a computer flash drive. By inserting it into one of the ports of the computer, the transfer of information is, say, 10 minutes, and in the next one for half an hour.

These and many other nuances are associated with port patency, and a usb tester will help identify the problem for its subsequent elimination. This is a compact device that reads the current readings and displays it on the display. Similar devices are used by electricians, but their testers require tuning and knowledge of the features of the tool. The usb tester is easy to use, and to get information, you just need to insert it into the port and, in some cases, turn it on.Now you know all about network bandwidth, and you can tell exactly which input is not working as it should. This device is necessary for both professional computer repairmen and ordinary users. For example, to control the voltage in the network, which, as you know, can adversely affect the battery of the device being charged, and in some cases disable it. To prevent this from happening, we have selected for you the 10 best usb testers presented on the Aliexpress site. Our rating includes both complex professional devices and household tools at the most affordable price.

TOP 10 best USB testers from Aliexpress

10 ATORCH UD18

The USB connector for this tester is just one of the directions. In addition to it, the scanner works with other types of connectors, which are located around the circumference of the case. On the one hand, this form factor is convenient, but only if the measurement is made at external outputs. When working with internal connectors, you can encounter a variety of difficulties. Up to the impossibility of inserting the device into the required input.

But here is the largest display on which all the data is placed, and you do not have to peer into the screen to understand what numbers are currently displayed. The possibility of output to a smartphone deserves special attention, but only by wire. The tester does not have Bluetooth and other wireless modules. Calling it the best definitely will not work, but the versatility of the design attracts attention. It is thanks to the form factor that this USB tester made it to our rating. Albeit not in the most honorable place in the top.

A standard USB tester is equipped with a small screen, while it needs to display a lot of data, which becomes very difficult to read, especially if you do not have one hundred percent vision. In this model, which is often called the best in reviews in all respects, a very large screen on which numerous scanned data can be easily placed.

There is also a handy menu that allows you to display the most important aspects on the screen, excluding others. Unfortunately, there is no multilingual support. The device recognizes only English characters, and displays them. Changing the language will not work even by updating the firmware. However, the menu is simple and intuitive. Apparently, this is also a reason for buyers to call the scanner the best in its category. We cannot give him a higher position in the rating, since there is no information about the accuracy of the measurements taken, and there are not enough comments for conclusions.

Aliexpress often comes across devices whose functionality has been deliberately cut. This USB tester is found on the site and as a regular tool that displays data on a small screen. Here we have an extended set of options. For example, the ability to connect via smartphone. The tester works through its own application, downloaded to a phone running any operating system.

Now you will receive information on the mobile screen, and you will not have to try to read data from a small display in an uncomfortable position.The only limitation concerns the "apple" technology. Only models of at least 6th generation are supported, but they will only work until the end of this year. Further, only iPhones from 7 and older. As for the technical aspects, nothing definite can be said. The seller from Aliexpress assures us of the accuracy of the measurements, but there are practically no reviews from real buyers on the site.

The charging cables that come with a phone or tablet often leave a lot to be desired, especially when it comes to obscure brands. Situations where one wire charges the device much faster occur all the time, and now a tool has appeared that is designed to solve this problem once and for all. This tester is an ordinary cable, but it has a built-in sensor that displays two parameters: voltage and amperage of the network.

In fact, these functions are quite enough to determine at what stage the failure occurs if you suddenly find that your smartphone has begun to charge more slowly. By changing ports, you can easily track which one works faster, as well as identify an input with a dangerous voltage. By the way, such situations also occur very often. For example, a standard splitter may work normally in some ports, but in some parts it may not give the appropriate data. With this cable, your device will be completely safe. You no longer need to fear for the safety of the battery, which can destroy excessive voltage in the network.

How much data should the USB tester capture and display? Each user has his own answer to this question, but we found the most informative device on Aliexpress, which analyzes 10 indicators at once and displays them. In addition to the standard voltage and amperage, there is a sensor for temperature, bandwidth, and the number of amperes transferred to the device.

But the main feature that is rarely found in such devices is the timer. Yes, yes, it would seem a simple function, but it is very difficult to find it. Using this device, you will be able to determine, to the nearest second, how long it took to charge your device. This helps to monitor the charge level, as well as monitor the health of the port and the battery being charged. And another important factor is the price. Despite the rather large amount of information provided and advanced functionality, the tester is relatively inexpensive, which is good news. By the way, reviews on Aliexpress about this device are mostly positive, that is, it does its job perfectly, despite the low price, which often misleads buyers.

Modern electronics manufacturers have long divided the world into two parts: some prefer to work with a small green robot, others with a bitten apple. There will never be a winner in this confrontation, but what about those who have not taken sides and are the happy owner of both? Before us is a USB tester that would certainly shock electronics manufacturers from two competing camps.It has both a regular USB output and a connector marked Type-C, known to all the "apple".

The connectors of both configurations are present both as an input and as an output, that is, in fact, you can use this device also as an adapter, charging, for example, an apple device from a standard USB output. Very convenient and eliminates the need to keep several testers. Everything compactly fits in one device, which, moreover, is as cheap as possible. Just over 500 rubles, even by the standards of Aliexpress is a low price, and if you look at the reviews, it becomes clear that the device is working properly and copes well with its tasks.

Professional USB testers, even not the best ones, are quite expensive, which is not surprising, given how many functions they can perform simultaneously. But the average user simply does not need them. There are slightly different tasks here: monitor the voltage in the network so as not to kill your electronics with increased current, see how much voltage has passed through the device, thereby determining the battery charge level. Or just monitor the temperature of the port.

With all these tasks, this device perfectly copes. In fact, he can only deal with them. This is the simplest, household tester without pretensions to professionalism. There is a minimum of information, and only one button responsible for turning the device on and off. Yes, it will not work to make a professional diagnosis with its help. For these purposes, completely different devices are used. But the price will please.Only 170 rubles for a full-fledged adapter with the display of, in fact, all the necessary information.

Many USB testers presented on Aliexpress cannot boast of high measurement accuracy. Moreover, there are ordinary toys with which you can get only approximate data. And, of course, they are not suitable for professional use. This tester is an exception, at least the seller and the cost of the device are trying to convince us of this.

The price tag is very high, but it is offset by the measurement accuracy, which is determined using professional oscilloscopes. Recall that this is from the words of the seller, and we do not have real data about the device. Reviews also do not allow to draw a conclusion. Apparently, not many buyers decided to purchase such an expensive device. But what you can praise the tester for is displaying a large amount of data. A lot of different positions fit on a small display.

Household, let's call them so, USB testers are able to read quite a lot of information and display it on the display. But if there is some kind of problem in the network, then you will have to look for it yourself. For example, port overheating. Most often it is associated with a short circuit or a poor connection. But which wire is to blame for this? Unknown. This device is just designed for such work. He not only analyzes the network, but also looks for problems in it.Its accuracy is calculated on the analysis of each contact in the port, that is, if one wire has a bad connection, the device will signal this.

Probably, in domestic use such a device is not needed, this device is for professionals involved in computer and electronics repairs. In their work, he is simply irreplaceable. You no longer need to visually look for a problem or completely change the port. It is enough to diagnose and identify the cause. By the way, poor contact often causes damage to the inputs. In fact, it does not even break, you just need to solder the loose wire a little. But finding this wire without such a device will be extremely difficult.

The first thing that catches your eye when looking at this device is a stylish design. This is indeed the most attractive tester on AliExpress, but its positive characteristics do not end there. For such a tool, external data is not the main thing. The main thing is its functionality, and everything you need is here. Maximum information on one display.

In addition to the standard voltage and amperage for such devices, there is a temperature sensor that shows how hot the port is. This is a very important indicator, since overheating means that there is a problem somewhere. Perhaps this is a bad contact of one of the wires, or a short circuit in the network. At this stage, they may not be critical, but sooner or later the port will fail, and it’s good if an expensive phone is not charged through it at that moment. In addition, this device can work as an adapter.On the side there is a micro usb port, that is, you get a full-fledged adapter with the function of testing the voltage in the network.
