USB Output Charging

1. As illustrated, lift the rear panel and plug an USB cable to the

charging port underneath.

2. Connect the other terminal of the USB cable with an external

device that needs to be powered / recharged.（ ）will start

flashing on the LCD to indicate the UM20 is connected with a

USB cable. After the device is fully charged, the（ ）icon

stops flashing and remains on constantly.

Priority Mode

1. When there is a power deficit for the UM20 to charge both batteries and USB device simultaneously,

the UM20 will prioritize the charging of the batteries or the device following the user’s preference.

When the top switch is set to BATTERY, battery priority mode will be activated. In this mode, the

UM20 will charge the batteries first. When batteries are fully charged or removed, the UM20 will then

charge / power the USB device automatically.

2. When the top switch is set to USB, USB priority mode will be activated. In this mode, the UM20 will

charge / power the USB device first. When the USB device is fully charged or disconnected, the

UM20 will charge the batteries automatically.

3. When charging 2 batteries simultaneously, output has to be at least 1000mA or above, when output

drops below 1000mA, the charger will charge 1 battery at a time.

NOTE: A small electrical current will keep passing through to the external device connected to maintain

the device in its full power state when it is charged.

Battery Activation

The UM20 is capable of activating over discharged protected Li-ion batteries. After battery installation,

the UM20 will test and activate the batteries before charging. Batteries detected as damaged cannot be

activated by the UM20 and «EE» will be displayed on the LCD to indicate an error.

NOTE: Nitecore does not recommend charging zero volt (0V) (over discharged) unprotected Li-ion

®

User Manual

Проблема в следующем. Поставив акки на зарядку и увидев что все нормально могу вернуться через некоторое время и увидеть что один акк в левом разъеме не заряжается. Просто застыл в одном положении. Дело не в самом аккуме т.к. было уже не раз и акк был другой. В чем может быть трабл?

• #2

Адаптер для зарядки должен выдавать минимум 2А, а в инструкции указан 1A для зарядки 2 аккумуляторов- это ложь. В машине стоит на 4.8А устройство и заряжает 2 аккумулятора на ура, дома зарядки от телфонов с 1А (1,2А) тоже не позволяли заряжать 2 одновременно. В итоге и дома появился зарядник на 5А.

• #3

Какие у Вас большие токи )))
Вообще я по образованию не электронщик, но уже не раз слышал, что при большом количестве Амперов, при зарядке аккумуляторов, получается большой нагрев самих аккумуляторов, что может привести к ббиг-бада-бум ))
Так же ходят слухи, что при больших Амперах аккумуляторы быстрее расходуют, отведенный им, срок жизни ))
Конечно же есть и большой плюс в больших Амперах )) Это скорость зарядки аккумуляторов ))

Поправьте меня, если я где-то ошибся ))

• #4

[ref:2xfapwrh]Cr0ssFire[/ref:2xfapwrh], да скорее всего у вас просто не хватает тока,
схема зарядки не справляется с правильным распределением
на 2 аккумулятора, литиевый аккумулятор до 90 процентов
заряжается малыми токами и большим напряжением, когда
его напряжение достигает примерно 4 вольта, правильная зарядка
переключается в режим стабилизации напряжения и держит
4.2 вольта но не ограничивает ток, далее происходит дозарядка
большим током до 98 процентов, на этом литиевый аккумулятор
считается полностью заряженным, его сопротивление вырастает
и большие токи перестают по нему циркулировать, зарядка
до 100 процентов может продолжаться такой-же период времени
как и до 98 процентов, аккумулятор остынет.

вообще все аккумуляторы должны правильно заряжаться током
1/10 своей емкости 12 часов, но химия литиевых аккумуляторов
позволяет заряжать их током 1/2 и даже 1/1 их емкости, для
быстрого заряда, не скажу что это плохо для аккумулятора
но если схема заряда правильно не работает, девайс дешевый
с плохой логикой то на незащищенных аккумуляторах можно
получить и бадабум

оптимально для 1 аккумулятора питание зарядки 1А,
если брать нитекоре то или на 1 аккумулятор либо на 2-4
но с собственным источником питания, он правильные
параметры выдает для зарядки.

нитекоре шикарные зарядки — сам пользую на 1 аккумулятор
собираюсь приобрести на 4 цифровой, вот хорошие:

• #5

g0nz1k12, с логикой у UM20 проблем нет и адаптеры в моем случае тоже с платой, нагрева не происходит. Sony VTC4 уже 2 года работает от разных зарядок включая эту.

• #6

Интересует меня, за какое количество времени заряжает данное устройство 4 аккума по 2500 махов?

• #7

Дабы не создавать новую тему спрошу тут.
Перестала работать данная зарядка, сначала просто заглючило её, пришел а аки на половину заряжены и экран моргает, я выключил и включил заново, всё стало норм, на следующий день история повторилась, на третий день совсем экран стал пустым, только подсветка горит, и естественно не заряжает. Я разобрал её, попротирал спиртом, где достал, и толи это помогло или то что я её вертел, но о чудо я включил и и увидел что всё работает, ну я на радостях побежал брать акум и ставить заряжать, но радость была не долгой и через минуту опять пустой экран, я повторил манипуляции со спиртом но толку ноль.
Что с ней случилось не пойму, её не кидали ни заливали, она несколько месяцев на одном и том же месте стояла.
Может было у кого нечто подобное, и что делали?
