KCX - 045 LCD USB Voltage Current Detector Battery Capacity Tester for Phone Mobile Power Bank

Small and cheap but unbelievably useful gadget when one is trying to determine why his phone or music player is charging so slow. It also has some other useful capabilities such as USB power consumption monitor and power bank capacity meter. Detector itself is very well built, precise and has easy to see numbers on screen.

In my case the usefulness of KCX-045 was proven straight out of the box. The USB cable, which I blamed before, was not the real cause of phone charging slowdown. The real culprit was USB ports in computer which was able to give only 0.5A charging current. Switched to charging from power adapter of WSX / MX X6A battery charger (in picture) and now phone is charging really fast.

Suggestion

- Numbers on display become translucent when looking to screen in step angle from above.
- Blocks second USB port when plugged in one of socket of 2 USB ports.

вообщем подтыкаем этот тестер к заряднику от него к телефону, планшету и узнаем сколько выдает зарядник, не просидает ли напруга. Ёмкость батареи тоже покажет. Все вроде верно, сравнивал с подобными тестерами. Единственное что не понятно что такое ваты, точнее что измеряет либо мощность самого зарядника или сколько он потребил ватт из сети 220. Ещё есть одна фишка которую я раньше не встречал может запоминать до 10 значений ёмкости батареи, это удобная штука, переключатся- дважды жмем как левый клик мыши начинает мигать индикатор выбираем слот в котором сохранить показания, и опять двойной клик. Спасибо гербест!

Покупал за 380 рублей.
Проверил на 2х амперном блоке питания от планшета ASUS, сам планшет, оригинальный провод Xiaomi покупал тут http://goo.gl/mcwro7 пропускает максимальный ток 1А и оригинальный провод LG покупал тут http://goo.gl/Cr9h9u пропускает максимальный ток 1,8А.
Тестер отображает такие параметры:
- Напряжение
- Ток заряда
- Мощность
- Емкость заряда
- время заряда
Имеется 10 ячеек памяти. Все переключения режимов осуществляются 1 кнопкой.

1. Extremely accurate device.
2. There is a deviation of the measurement of 1-2% only if you reach the end of its capabilities ( 3 - 3.5A input)
3. As far as you use it typical occasions (350mA - 2000mA) it is dead on sharp !
4. There is a reason being that accurate is the "HOLTEK LCD controller" on the bottom of the board.The same microcontroller was partially spoiled by the cable in "KCX - 017". But in "KCX - 045" there is nothing to mess with good job of "HOLTEK LCD controller" !

Suggestion

1. It's wasn't that cheap, when I bough it :-)
2. The package is just a plastic bag
3. It's a Must Have Scenario !

wow! all these features in a so smart, simple to use device is very usefull...you can check any USB port with it, and believe me, checking USB ports before use (at least on first use) is important because you can really burn your phone and even your house with a bad USB charger, and don't believe you will never have a bad charger, you can find them everywhere..
Conclusion: very usefull, well made, quality materials & finish, simple to use, full of capabilities, really nice display, excellent price!

For that kind of product this one here is like Porsche.
If you want to check the current charging or check your charger (is still good enough?) this voltage tester is best to do that.
Quality is awesome. LED screen is small but very convenient. Numbers and letters are legible.
Very useful tool. I recommend.
Thanks GB for a quick delivered.

Очень удобный гаджет, позволяет контролировать заряд мобильных устройств и всего что питается от usb.
10 ячеек памяти, отображает mAh, время зарядки, вольтаж и амперы на выходе. На входе показывает только вольтаж, если не подключен потребитель!
Очень полезная вещь, всем рекомендую!

2. Long button press, clear memory and go to next memory place.
3. 2 short presses, blink mode for memory reading, one short press next memory without deleting, 2 short presses stay in that memory.

This device shows your USB output voltage and charge rate when used in-line with a charger.
The best part is that it will also show the capacity and charge status of your battery.
Absolutely essential for anyone who needs to store batteries at a nominal charge. Recommended.

Strumento utilissimo per tenere sotto controllo il voltaggio che scorre tra una sorgente ed un dispositivo. Dispone anche di un circuito di protezione che evita i sovraccarichi di corrente, salvando il dispositivo collegato. Un'altra comoda particolarità è quella di segnalare gli effettivi mhA accolti dal dispositivo, in modo da conoscere la vera capienza dell'accumulatore. Ottimo!

Suggestion

Non ho rilevato alcun tipo di difetto o problema.
