    Fast delivery to MSK. There was an analog of 13 in 1, worked for several months and began to catch the flakes, ordered this one, let’s see how much it is enough. Yuzai actively, and 12 V batteries charge, you need to understand the voltage and how much took charge.

    G***v –

  62. M***k –

    The item is excellent ordered the maximum set, the item shows Volt consumption, and how much the Amper phone requests, and the temperature, also if you drown the phone to zero and then charge through the tester to hundreds it will be that the phone is new or old then the capacity of the mAh battery will be less than stated. There are also memorizations of different readings for example, forgive the presses for a second, then the device to switch from the bottom left changed the digit from 1 as you switch to 9 Memory modes, with the при button for 8 seconds reset one одной memory, you can tell for a long time, but don’t hesitate. The product is usable.

    I ordered 11.11 came 3.12 to Chelyabinsk. Everything works. I do not know about the accuracy of the testimony, I did not check. But according to reviews from YouTube, the error in measuring the capacity is about 20%. In short: Who needs accurate readings, USB testers will not work.
