The first group of pictures charger test

For iPad original charger, connected to the 2A load resistor and mobile phones, the measured value of the maximum current and voltage is 5.01V 2.28A, exceptional charger.


For iPad original charger, connected to the 2A load resistor and mobile phones, the measured value of the maximum current and voltage is 5.01V 2.28A, exceptional charger.

Use 2A load resistor to connect with Salcomp (a Nokia company) charger, the output and voltage is 5.01V 1.89A

Connect 2A load resistor and mobile phones to Salcomp (a Nokia company) charger , the measured value of the maximum current and voltage is 5.06V 2.20A, very good charger.

Mobile power connector USB HUB for mobile phone charging, the measured voltage and current values 5.00V 0.44A


Mobile power via USB HUB, connected to the 2A load resistor and mobile phones, the measured value of the maximum current and voltage 4.86V 1.96A, still good mobile power.

The second group of pictures USB data cable tests

1m original data cable of LG, 1A current charger, USB tester, test result 4.8V 0.92A

1.5m original data cable of Samsung, 1A current charger, USB tester, test result 4.80V 0.92A

Orange data cable, 1A current charger, USB tester, test result 4.22V 0.81A. This cable quality is no good.

Mobile power discharge capacity test

Beginning discharge is 0001mAh

After 10 minutes the discharge capacity is 0164mAh

We conclued that the charging current is 0.98A, after 10 minutes the discharge capacity is 164mAh.

Note:This data is mobile power discharge capacity, not battery capacity. According to our experience, the mobile power discharge capacity is about 1.9 times of the battery capacity.

    USB тестер KCX - 017
    Color:White
    Простой в использовании, компактный измеритель текущих значений напряжения и тока, проходящих через USB-порт. Отлично подойдет для проверки работоспособности USB-портов, проверки качества кабелей, зарядных устройств и т.д.
    Также данный тестер обладает чудесной функцией - измерением потребляемой энергии (заряда в мА·ч), что позволит Вам оценить реальную емкость батареи (в телефоне, плеере и тд.) или какого-нибудь повербанка.
    В отличии от более простых моделей - вывод значений напряжения и тока на дисплее происходит не поочередно, а одновременно.
    Ежесекундное обновление данных
    Встроенный MicroUSB разъем
    Сохранение в памяти до 10 результатов измерений
    Suggestion
    нет

    KCX-017 3-15V USB Mobile Power Charger Capacity Current Voltage Tester Testing
    Color:White
    I recommend this product.
    Control:
    Switching between the memory cells 2 times quickly press the button, USB meter starts flashing backlight. A short press of the button toggles cyclically
    memory cell from 0 to 9.To exit the shift mode as well 2 times quickly press a button and the unit will return to normal operation.In USB mode, switch the
    tester stops the expense of load capacity.Clear Memory: within 3 seconds, press and hold the button.The unit switches to the next memory cell, the counter load capacity which will be reset to zero. Release the button.
    Suggestion
    The device dont show the charging time.

    Really Good quality for a good price
    Color:White
    Good quality item: I use it to better understand how much juice I put in a lithium battery in order to see if it reach the nominal capacity or if it is at the end of life.
    So far the reading seems really accurate compared to my Imax B6, and the build quality is good for the price payed. It doesn't overheat, it doesn't smell "plasticky", overall I am really satisfied with this product.
    For this price point I can recommend it to anyone.
    Suggestion
    None really for now. We will have to see the durability of the screen, but I am confident.

    Current voltage tester KCX-017 LCD
    Color:White
    - works perfectly, it is a great "toy" for big boys :-)
    - you have to love it, I use it with solar charger to chrge up power banks and you quite precisely know how much charge you got
    - you get 10 memory slots that you can use for different devices (it records mAh you got on particular slot)
    - it is intuitive to use
    - I would most definitely buy it again
    Suggestion
    - none, it is great

    Нормальный прибор
    Color:White
    Удобная штука, особенно когда нужно определить идет зарядка или нет (на "мёртвых" андройдах) + показывает миллиАмпер часы которые взял в себя аккумулятор. Короче, кому надо - рекомендую. Кстати удобно проверять USB зарядки и пр. на предмет реального тока, а то модно стало писать ток 2 Ампера и больше, а реально всё гораздо печальнее...
    Suggestion
    Пока не обнаружено.

    Universal Tester
    Color:White
    It's very useful and practical item. easy to work with. Charging of smartphone or tablet os some another device can be under control. Testes everything starting from simple chargers, to power banks. You can check how much energy goes to you device battery and how much it holds.can check how much gives your power bank.
    Suggestion
    It has good design, digits on screen are clear and good visible. also it has 10 memory cells for 10 different devices. You can change the cell by double tapping the buuton and after choosing by one tap.

    USB Multimeter
    Color:White
    I got this "meter" to get an overview of what cell phone and Co so absorb everything. Also to see to what extent the manufacturers indicate the capacity and the charging current.I do not regret the issue by no means, because so many chargers, which pretends to have a load current of 1A, brings just half.
    Clear purchase recommendation, for all who want to go to the search of USB-Strom!
    Suggestion
    no

    This is a "must have" item.
    The precision is high and it produces reliable values.

    You can not only check the quality of USB Power sources, you can even check the quality of USB Cables. USB Cables are of very different quality from low to high.
    With this Voltage Tester you can check the quality of the cable and the quality of the usb source.
    Suggestion
    none.

    Good tester for all USB items
    Color:White
    Good quality building and a great price for this voltage current detector. I tried it with power banks, tablets, smartphones, ip cam and every time it worked very well and it told me the voltage and the current ampere. I advise this product and for this price it is a must have.
    Suggestion
    Nothing to report.
