Pros:
Potentiometer Adjustment Direction: Clockwise (increase), counterclockwise (decrease) Second potentiometer is useless. Minimum output current: 0.4A Max output current without heat-sink : 2A Dropout Voltage = 1v minimum Italian: Economico, piccolo e funzionale. Se si girano i potenziometri in senso orario si aumenta la quantità, se si girano in senso antiorario la si diminuisce. Il potenziomentro al centro è inutile. Corrente minima che si riesce ad impostare: 0.4A Corrente massima senza dissipatore: 2A Differenza tra V ingresso ed uscita è di almeno 1v
Cons:
There is no instruction manual. Italian: Non c'è un manuale di istruzioni.

Pros:
- You can regulate voltage and it indicates when the battery is completely charged - Came with an anti static bag. - Has a wide voltage range - I have to say that it does its work perfectly, but i think it's more than enough for only a charger.
Cons:
Nothing.

Pros:
Купил несколько таких регуляторов, смысл описывать не имеет. Все знают для чего они. Регулировку по току, по напряжению, по защите. Можно литий заряжать.
Cons:
Свои функции отрабатывают, может параметры немного завышены. Нет индикатора, но это за другие деньги.

Cons:
none
