10 best voltmeters with AliExpress

Everyone knows about the purpose and application of voltmeters for practical purposes, who somehow came across the repair of electronics and electrical circuits in general. They are used to measure the voltage or the EMF of the circuit, and may also contain additional measuring circuits (work in multimeter mode).

According to the principle of operation, voltmeters are divided into:

• Electromechanical - historically, the first type of voltage meters, morally obsolete, giving large errors and gradually emerging from production (for some varieties);
• electronic - analog and digital voltmeters with high measurement accuracy and widely used in electrical engineering industries.

Since the measuring device is not a fundamentally complex structure, a huge number of companies around the world are developing it. With the development of the Chinese marketplace AliExpress at domestic consumers, a good opportunity has arisen to acquire goods (including voltmeters), the cost of which is an order of magnitude cheaper than market. In this regard, we have compiled the rating of the ten best electronic voltmeters for voltage measurement, presented in the assortment of Aliexpress store.

Best digital voltmeters

Standard digital voltmeters are used to determine the voltage in an electrical circuit and diagnose electrical components. The advantage of such devices over conventional electromechanical meters is the high accuracy of measurements and the simplicity of information presentation. The only drawback of electronic digital voltmeters lies in the obviously lower degree of reliability - circuit elements are very sensitive to high applied loads, and also do not tolerate strong mechanical shocks.

4 Inpelanyu C1187

Our miniature and compact voltmeter from Inpelanyu opens our rating. The device is a small board with a display (supplied in three colors), to which, accordingly, the value of the measured voltage is displayed. Such a design can be used for a variety of purposes (for example, as an indicator to a charger or for an on-board vehicle network), easily connects and measures very reliably (the product is quite popular on Aliexpress and, therefore, its error has been repeatedly checked by customers). In addition, the board has a trimmer, which will help to achieve accuracy in a particular range. There is also a kind of protection against improper installation - if you mix up the polarity of the wires, the display simply does not turn on.

3 Diymore 100V 10A

By type, this device is similar to the voltmeter described above, but Diymore is no longer so primitive and can show not only voltage, but also amperage. For the rest, there are practically no differences, the principle of operation and the scope of application of the counter are identical. There are no special complaints about the accuracy of measurements, however, many users note the difficulty of connecting a voltmeter (there is no circuit or instruction in the kit, and not everyone can independently figure out the pinout of 5 wires).

2 Inpelanyu Q0621

This sensor is positioned by the manufacturer as specifically designed for use in cars (motorcycles). Such an adaptation of the device is expressed in the fact that to connect a voltmeter you don’t have to solder and mount anything extra - simply insert the device into the cigarette lighter, after which it will inform you in real time about the current on-board voltage and the temperature inside the car. This is both the main advantage and the main drawback of the gadget. The advantage is that, as already mentioned, any user can connect Q0621, regardless of their ability to solder, etc. - The voltmeter only needs to be placed in the designated connector.

The downside is the following: the gadget will occupy a very useful cigarette lighter slot, and its case does not even provide a usb-input for charging. Naturally, if a car owner at least a little versed in technology, he would rather spend time and connect a simpler but autonomous voltmeter.

1 KETOTEK AC20A

The device embodies the maximum of what a compact measuring sensor can contain. Small in size, the device combines many functions and is able to simultaneously display voltage, amperage, energy and a number of other not so important indicators. There are opportunities for additional manual adjustment for specific conditions (for example, setting the maximum power). And if the accuracy of the measurements didn’t notice any complaints, the display seemed dull to many (the most contrasting image is obtained when viewed at 45 degrees from the bottom to the screen plane), and from certain angles it is almost imperceptible.

Best portable voltmeters

In this category, we will discuss devices that can operate without being directly connected to an electrical circuit. Voltmeters of this kind are mainly used by electricians to quickly determine the presence of voltage in a particular area.

3 MESTEK MT898

A good choice for electricians and other professionals, often working with voltage. The gadget has a contactless technology that allows you to recognize the data on the presence of voltage, without touching the wires themselves and thus without breaking their isolation. The model has the appearance of a ballpoint pen with a special clip (for better fixation in the pocket), assembled from high-quality plastic and equipped with two sensitivity modes (the first determines the phase / 0, and the second is designed to search for hidden wiring). You can also customize the display (sound or light), and in low light use a flashlight.

The device works only from AAA batteries (it will not work to connect the batteries) and, as you probably already understood, cannot measure voltage directly (and only shows its presence).

2 UNI-T UT18D

Worthy of mention is the UNI-T UT18D portable voltmeter, original in both performance and performance. In the prefabricated building, consisting of two segments, probes are located to measure the voltage at the terminals of electrical circuits. Each of the segments is made in the form of a convenient handle and painted in black and red, respectively.

Judging by the description from the seller, UNI-T UT18D is designed to measure voltage in the range from 12 to 690 V. Such a spread of values ​​gives the device some versatility, but the accuracy with a three-digit display of the result will be clearly not enough. The requirements for operation are not impressive either: correct operation of the voltmeter is guaranteed only at temperatures from -12 to +40 degrees Celsius. Despite all the limitations and conventions, consumers give the model extremely high marks. Perhaps the technical characteristics with ergonomics and are decisive indicators, but they are not able to justify alone the requested price.

1 OOTDTY 1A10388-BK

A classic multimeter, great for both home and professional use. Many different functions are concentrated in one device (voltmeter, ammeter, resistance tester), and all of them work at different frequencies and ranges. There are overload protection and test leads for safe connection, and the gadget itself, although made in China, is very similar in design and design to the brainchild of Soviet electronics (which for many is almost the standard of reliability and quality).

Despite the fact that the principle of operation of OOTDTY is not very complicated and obviously will not cause difficulties for experienced users, for beginners the device risks to seem too tricky and unsafe (this is also promoted by the absence of Russian instructions). However, the network is full of detailed manuals and tips, so that almost everyone can understand.

The best voltmeters for USB ports

Voltmeters for USB ports are miniature wiring devices based on the same principles as standard electronic models. They are used to diagnose the state of the USB connection interfaces, displaying measurement information on a miniature display. It makes no sense to talk about the advantages and disadvantages of such devices, since USB voltmeters have no analogues that perform a similar function.

3 JUANJUAN USB Tester

The irony of the budget voltmeter from the company JUANJUAN lies in the duality of impressions from the statements of users and what technical characteristics gave it the developers. First, the narrow range of voltage measurement is noteworthy - from 5 to 20 V, respectively. Secondly, the measurement error (in the best case) is about one percent of the result — in some systems such an accuracy indicator is unacceptable, and can lead to an erroneous rejection or the notorious omission of an obvious defect. These factors are enough to stop treating a voltmeter as one of the best, but buyers have their own opinion on this matter.

Actually, it is not so much the quality of the JUANJUAN USB Tester that is estimated, but the fact of its functioning. The seller also played a big role in popularization: the speed of delivery also leaves a pleasant impression. But the main advantage of the voltmeter is the level of cost: it is almost impossible to find a working analogue for a similar amount.

2 ATORCH 12 in 1

This USB tester is primarily distinguished by high measurement accuracy, repeatedly verified by customers from all over the world. The device displays standard information about voltage, amperage, resistance, battery capacity, current temperature and charging time, and the display itself has several backlight modes. Despite the fact that the device is positioned as super-functional (marking 12 in 1 will remind many times the times of Tetris and cartridges for Dendi, where the number of games was considered in a similarly obscure way), there were no unusual or interesting possibilities. But ATORCH has an internal memory (that is, even when disconnected from the network, the device remembers information about the last connected device, which is very convenient, for example, when testing banks).

1 HIDANCE 2USB-A1

HIDANCE 2USB-A1 is one of the most popular USB voltmeters presented on AliExpress. It has a wide range of voltage measurements (from 3.6 to 32.5 V), as well as current strengths (from 0 to 5 A), cell temperature and power (up to 300 W).Measurement errors at such indicators are about one hundredth of the result, but for active power this indicator is at the level of thousandths. The undoubted advantage of HIDANCE 2USB-A1 are also adequate conditions for operation: the temperature value should not fall below -10 and not exceed the mark of +60 degrees Celsius.

For several years of active sales, the device was bought by more than ten thousand people, which is a clear proof of its reliability. Given the level of cost requested by the distributor, and putting together all the above indicators, we get the best USB voltmeter in its category.
