    Delivered in a tasteful tin box. The inside is lined with a tightly fitted sponge, so you have to pull a little to get it out of the box. ;)
    The tester comes in two versions: UM24 without Bluetooth interface and UM24C with Bluetooth. The difference in the bottom PCB, where or not the Bluetooth interface is soldered.

    The meter itself is quite an interesting design with a few unique features, especially one. It is the measurement of the power cable resistance. And the ability to control its functions from a smartphone, of course also from a computer.

    The meter has a color display with a diagonal of 1.44 '.
    Its measuring range is 4.50-24.0V / 0.00A-3.00A.
    The resolution is 0.01V and the accuracy class is 1%.
    When connected to the power supply with any button pressed, we enter the menu, in which we can set the Chinese or English language and reset its settings. Nothing fancy so it's not there.
    However, an interesting feature is that the displayed image can be turned every 90 so that the measurement results are most conveniently read.

    In each screen there is a "Help" button and there we get instructions what each button can do on a given screen. A distinction is made between a short press and a long press. Help available in the selected language.

    The exact dimensions are available in this picture.
    However, the available information screens without the help menu are shown below.

    As you can see - the first one measures the voltage, current, temperature of the device and the following calculated: capacity in mAh, energy in mWh, current power in W and load resistance.
    The device has 10 memory cells in which we can view the results of previously made measurements: groups 0-9 menu.

    On the second screen, in addition to voltage, current and temperature, we have the voltage on the D + and D- cores and the recognized fast charging mode, if, of course, the charger provides one.

    On the third screen, we have capacity, work and time.
    Another interesting feature is the ability to set the load from which the meter is to record parameters. This is a nice option that allows you not to count the cable connected to the output of the device (some have resistors and take a little current) or to eliminate the idle run of the powerbank, which uses some electricity for indicators and its electronics without charging the battery anymore.



    Another interesting fact on the fourth screen - measurement of the resistance and voltage drop of the connecting cable. Here we can check what quality cable we have. It is worth comparing the difference between the factory cable and the non-original one. The differences are sometimes colossal, so we will not be surprised why the phone is so slow to charge on this cable. This is quite a unique feature.
    It is true that I managed in a different way without it and I had information about the quality of the cable, but here the manufacturer gave such a cymes and praise him for it.

    The fifth and sixth screens use the capabilities of the graphic screen and we have a voltage and current graph.
    On the last screen, we can set the timeoutscreen (unfortunately consumes some electricity, so its lighting falsifies the results of measuring the powerbank's capacity), the brightness level and the temperature display in C or F.
    And now the most important highlight of the program - the Bluetooth interface. With its help, we can read and log measurement data on the computer. This is what the program looks like, which is additionally paid:

    As well as recently, a program for Android and iOS has been available that allows you to view the parameters and control the meter.

    As you can see, this is the Polish language version. The project is free and will be developed.
    This is how it can be seen on the meter screen:

    I would like to add that the BT version has a red LED on the side, which flashes when the device is not connected and lights up permanently when connected. At this point, the device's screen is also turned on.
    Current consumption with screen on and off.

    Consumption is slightly lower without Bluetooth interface.
    And an example of the help menu.

    And here after flipping the screen.

    In the background, you can see a candidate for the next article. This is by the way.
    The current consumption with the screen off varies 0.069-0.085W, with the switched on from 0.135-0.155W.
    In line with the blinking of the BT diode. After establishing a connection, the consumption increases by 0.02-0.08W.

    Where and for how much can you buy it?

    I see a friend @kkknc or maybe Jacek presents here and he sells on OLX, I have the impression that even the same photos are ... I wonder how good it is, because it's a bit of a free advertisement ... The offer on OLX is exactly what's here on the electrode it presents, there is no word about OLX, but after entering it pops up in one of the first positions ...
    There is a section for sale here, that would be fairer.

    I do not see there that someone from OLX was directing here and here on OLX.
    But I will see if someone took my photos.

    Maybe it's just a coincidence :) that what a colleague presents here, someone else has such an assortment on offer ...

    There are fewer things in the assortment and not everything overlaps. I also watched. Other descriptions and a distance of 30 kilometers. I also have the usual UM24 without BT. I have 35W loads, which I will present soon, I do not have a transmitter. My descriptions are fresh and as I see those ads refreshed. So it's been there for some time.

    He he will come in handy, just some time ago I also ordered this tester in the BT version (included with the QC trigger) and it should be in PL soon (at least one package from orders that day is already in PL). Purchased in the same way from HIDANCE, moreover, this is not my first purchase with them and you can easily recommend this store. The mentioned version (tester + trigger) with shipping came out PLN 77.67 ...

    For my part, I also highly recommend the HIDANCE store.
    I also buy from nothing. And once I got the thing, unfortunately not working. So for Chinese terms, they responded fairly quickly. Because I think the three days have passed. And they sent the second copy without any problems, which somehow arrived in 2 weeks. Yes, this is a company.
    PS. A newer cooler version is now available. It's called UM25 / UM25C.
    I will introduce her as soon as time permits.

    Well, I think I will hold back (I have enough of these testers at home) from what I can see USB-C ... the rest, looking at it quickly, are probably just frills (colors etc.)

    In total, for some time in the above-mentioned store there is also "POWER-Z USB tester QC3.0 / PD" - except that the price of "this teges" is so-so, or at least UM24C, at the moment for some quick tests of chargers / wires are enough ... Maybe if I have more USBC equipment, you will think ...

    The tester has not changed, there are some things in the software. And it's up to 5A.

    @kkknc

    When you order, take some photos of the PCB to compare what they changed in the hardware :)

    On the other hand, there may be some haunted person who wants to create their own firmware on this STM8 :)

    There is. Just time. ;)


    And calmly, as they say, "it is not burning" - just as more out of curiosity as you will be making a description :)
