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.

Very useful

Pros:
Very useful and has multiple mAh record slots.
Cons:
The internal software has a minor flaw. When trying to clear the value from a memory slot after you go to it, it clears the next one instead. So if you want to clear the one you're using, you have to skip through the next 9 until the one behind the one you're using, and hold to delete.

Tester USB

Pros:
Robi to co ma robić to małe urządzenie, wyniki podaje dokładne jak za tą cenę.
Wykonanie nie jest idealne, ale czego spodziewać się za taką cenę. :)
To wyjście USB mogłoby być lepiej osadzone, żeby nie latało tak jak ma to miejsce teraz, ogólnie to na plus. :)

Cons:
Słabo osadzone wyjście na kabel USB poza tym to nie ma się do czego przyczepić.

Самый народный надежный тестер!

Pros:
Пользуюсь им уже более 2.5 лет, за это время выручал меня много раз.. и кабель протестировать.. и зарядку.. и аккумы на телефонах
с его помощью много хлама отсортировал.. таскаю все время с собой. Тестировал до 3 Ампер - все норм.
+ есть mini-usb вход, много выдаваемой информации (емкость, вольтаж, ток), память на 10 устройств. + есть нагрузочные резисторы.
- нету (ну разве что на резисторах переключателя нет на 1А/2A (идет на 1А)

Cons:
Отличный проверенный народный тестер!
