10 best USB testers with AliExpress

Have you encountered a situation when charging the phone from two different chargers, you clearly see the difference in time spent on a full battery charge? It seems that the wires look alike, and the adapters are no different visually, but after the first one, the phone is fully charged in two hours, and after the second in four. Or another example: a computer flash drive. By inserting it into one of the computer ports, the transfer of information is, say, 10 minutes, and in the next half an hour.

These and many other nuances are associated with the port's throughput, and a usb tester can help identify the problem for its subsequent removal. This is a compact device that reads the current and displays it on the display. Such devices are used by electricians, but their testers require tuning and knowledge of the instrument's features. Usb tester is easy to use, and to obtain information, simply 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 does not work 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 a charging device, and in some cases disable it. To avoid this, we selected for you the 10 best usb testers presented on the AliExpress site. Our ranking includes both sophisticated professional appliances and household tools at the most affordable price.

The AliExpress platform is attractive for many buyers, first of all, for its most affordable prices. But often, the cost of some products can hit even the most experienced user. As, for example, this USB tester, the price of which is less than one hundred rubles, and this is taking into account the shipping and delivery.

Yes, this device does not differ informative and wide functionality. In fact, it tracks only two parameters: the number of amps in the network, and voltage. Of course, it is not suitable for professional testing, but for home use it is the best choice. Having inserted it into the adapter of the charger, or into the port of the computer, you will receive all the necessary information. The tester will show if the port is working normally and if there are any errors in it. To diagnose a problem in case of detection, the device will not be able to, but we recall that its main task is not in this. It simply shows the basic data on the voltage in the network, and you should decide what to do with it already, and it is better to entrust the repair to professionals.

A wireless connection, which 50 years ago would call magic, is today a thing of everyday life. Using a smartphone, you can manage your entire home, including your USB tester. This is the best device in terms of obtaining information. With it, you are not limited to a small display device, which is difficult to see something. And if you need to test the port in the back of the computer? In this case, this model is simply irreplaceable.

When you turn on the tester in the network, you receive a signal over a wireless network that displays all the necessary information on the smartphone screen. Here and voltage, and network amperage, and even fluctuations. That is, we also have an oscilloscope, albeit in a compact package. By the way, through a smartphone, you can not only receive information, but also manage the tester. Of course, we cannot affect the network performance, but we can turn the device on or off when we need it.

How does a driver start driving? With seatbelt fastening? Or starting the engine? Perhaps, but most of us sitting behind the wheel first of all put on charging your smartphone or tablet. And this is despite the fact that the harmful effect of DC current on electronics, and in particular the voltage coming from the cigarette lighter, has long been known.

Before us is a device that can monitor the voltage in the automotive network. There is no huge amount of read data. They are simply not needed. The device is designed to show what voltage is present in the network at the moment. If it is significantly higher than what is indicated in the documents for the device, you should not charge it. And it is better to contact the mechanics, as there is a problem in the car. In addition, this device is a splitter, that is, you get a full-fledged HUB cable, with a display on which the voltage is displayed on the network. Simply put, this is a simple, but very necessary device that should be in every car, especially if it is not the first freshness, and problems in the wiring are quite possible.

Charging cables that come with a phone or tablet often leave much to be desired, especially if we talk about little-known brands. Situations where one wire charges the device much faster are encountered all the time, and then a tool has appeared designed to solve this problem once and for all. This tester is a normal cable, but a sensor is mounted in it, which displays two parameters: voltage and network amperage.

In fact, these functions are quite enough to determine at what stage a failure occurs, if you suddenly discover that your smartphone has started to charge more slowly. Changing the ports, you can easily track which of them is faster, as well as identify the input with dangerous voltage. By the way, such situations are also very common. For example, a standard splitter in the part of the ports may work normally, and in the part it may produce incorrect data. With this cable, your device will be completely safe. No longer need to fear for the safety of the battery, which can destroy excessive voltage in the network.

How much data should USB tester record 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 on the display. In addition to the standard voltage and amperage, there is a temperature sensor, bandwidth, and the number of amps transmitted 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 can determine, with an accuracy of a second, how long it took to charge your device. It helps to control the level of charge, as well as monitor the performance of the port and rechargeable battery. And another important factor - the price. Despite the fairly large amount of information 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 an excellent job with its task, despite the low price, which often misleads customers.

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. In this confrontation there will never be a winner, but what about those who have not taken sides and are the happy owners of both? Before us is a USB tester, which would surely shock the electronics manufacturers from two competing camps. It has both a normal USB output, and a connector labeled Type-C, known to all "apple makers".

The connectors of both configurations are present both as an input and as an output, that is, in fact, you can also use this device as an adapter, charging for example an apple with a standard USB output. Very convenient and there is no need to keep several testers. Everything compactly fits in one device, which, moreover, is as cheap as possible. Only 500 rubles with a little, 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 with its tasks.

Professional USB testers, not even the best, are quite expensive, which is not surprising, considering how many functions they can perform at the same time. But the ordinary user simply does not need them. Here are a few other tasks: to monitor the voltage in the network so as not to kill your electronics with an increased current, to see how much voltage is passed through the device, thereby determining the level of battery charge. Or just track the temperature of the port.

With all these tasks, this device is excellent. More precisely, only he copes with them. This is the easiest, household tester without claims to professionalism. There is a minimum of information, and only one button, responsible for switching the instrument on and off. Yes, to make a professional diagnosis with it will not work. For these purposes, completely different devices are used. But the price will please. Only 170 rubles for a full-fledged adapter with display on the display, in fact, all the necessary information.

The task of the USB tester is not only to analyze the network and the voltage in it, but also to save your device from dangerous vibrations as well as overcharging. Yes, most modern phones and other electronics have built-in protection against overcharging, but are you sure about it?

This device is capable of beeping and this is its main feature as well as advantage. For example, you charge through it a tablet. Yes, yes, this tester works as an adapter, that is, it is able to read the charge that has already passed through it. As soon as the battery is fully charged, the device will beep. Also, the alert will work when the network reads out of range. For example, the temperature in the port has risen sharply, which tells us about contact closure. Or the voltage has greatly increased, which threatens to damage the charging device. You will receive timely notification of all these problems, as well as all the information that is displayed on a small but most informative 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 a problem with the network, you will have to look for it yourself. For example, overheating of the port. Most often it is associated with the closure of contacts or with 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 poor connection, the device will signal this.

Probably, in domestic use such a device is not needed, this device is for professionals involved in the repair of computers and electronics. 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 becomes a cause of input breakdowns. In fact, it does not even break, just need a little solder the detached wire. But to find this wire without such a device would be extremely difficult.

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

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