The first group of pictures charger test

iPad original charger connected to 2A load resistor, the output current and voltage is 5.01V 1.89A


iPad original charger via USB HUB, connected to the 2A load resistor and mobile phones, the measured value of the maximum current and volatage is 5.01V/2.28A , very good charger.

Salcomp (a Nokia company) charger connected to 2A load resistor, the output and volatage is 5.01V /1.89A

Salcomp ( a Nokia company) charger via USB HUB, connected to the 2A load resistor and mobile phones, 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

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

Samsung 1.5m original data cable, 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.

    A little manual for USB tester
    Color:White
    Pros:
    There are a lot of reviews about this well known USB tester here, so i just want to write a little hint about using this device.
    1. To switch the memory slot, press the button twise . LCD display will
    start blinking. Then press ones to change slot. Press twise again to keep a choise.
    2. Press and hold button for a few seconds. By this way, your will switch to next store bank and will reset its data.
    3. LCD screen will flash if voltage is too high or too low (you will see updown alert arrow near the voltage value).
    4. Be careful, the resistor module heats up to the 100 Deg C less than two minutes.

    1. Чтобы переключить слот памяти, нажмите кнопку дважды. Экран замигает, нажмите один раз, чтобы переключить слот.Нажмите дважды еще раз, чтобы сохранить выбор.
    2. Зажмите кнопку на несколько секунд, чтобы переключиться на следующий слот памяти, обнулив его значения.
    3. Дисплей мигает, если входное напряжение слишком маленькое, либо слишком большое (на экране замигает стрелка).
    4. Резистор нагревается до 100 град.С примерно за минуту.
    Cons:
    A little overpriced. Non switchable resistor module.

    Отличная штука.Показывает ток заряда.ток потребления,напряжение.Сразу отбраковал "левые" шнурки.Думаю,что не ошибусь,если разделю мнение предыдущих отзовиков.что этот мини-тестер может претендовать на звание "народного"
    Cons:
    нет

    Excellent
    Color:White
    Pros:
    - You can measure how much power your devices consume.
    - its precision is amazing.
    - if you have a power bank it's very useful because you can see how much mAh has been consumed while you're using it.
    Cons:
    Maybe the quality of the plastic case, but everything is ok
