Hello everybody! Today in the video instructions will be a tester and the necessary addition to it - your load. I will not go into the characteristics and devices of these devices (you can read them by clicking on the links in the description), but just show you why they might be necessary for you. So, the first device is a usb tester and from the name it is immediately clear that he is testing everything that is somehow connected with us. Suppose you need to check the actual battery capacity of your phone, smartphone, tablet, MP3 or MP4 player, etc. You turn on your charger, connect a tester to it and already connect your discharged device to a tester. At the end of the charge, you can see how much energy is poured into the battery of your gadget and add 10-15% to this number, since the device of the smartphone's shooting gallery is almost never “0” discharged. Let's try. Here is our smartphone and let's say it is discharged. We take the charger, connect it to 220, turn on the tester, then connect the cord and insert it into the smartphone. After we connected the USB tester to the smartphone, we observe such a display. You already see what each line stands for. 1 volt, i.e. how much volt comes from the charger to the smartphone, 2 how many amperes, 3 device temperature, 4 how much time has passed at the moment from the start of charging, 5 power, 6 watts / hour, i.e. how much has given and finally 7, the most important line for you is that this is how much energy will flow from the charger to your smartphone battery. Well, with all the notation, we figured out and now let's move on to the next test, which you may encounter in practice when using the USB tester. The next test is to verify PowerBank. Here I have an old YooBao and it has 2 sockets, one for 1A, and the second for 2A. Let's check that at 1A. We insert and see that this socket is really 1A at 5V, but 2 nests at 2A pumped up. Already sagged and we reduce the load. That's just 0.66A was 5V. That is, this nest is only at 0.66A, and it is written that at 2A. So that's it. But here is this PowerBank, this is not mine, this is a son, let's watch. 2A and the voltage did not subside. We increase the load to 2.4A and only then the drawdown begins. This PowerBank is also made in China and is written 5V and 2.1A. In the same way you can check and charging. This is really the original charging from Samsung. We insert it into the outlet, insert the usb tester into it and see that it is 1.15A, and it is written 1A. I was struck by this charge, a Chinese replica of Samsung for 3 sockets. We check and see that it copes very well with the load, that is, it can charge energy-intensive devices. All 3 sockets give 2A each. That's all, thanks, bye-bye.
