    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    - can be powered from 100 to 240V (US to Europe)
    - implemented auto-cut-off protection
    - buil in timer (6 hours as stated in manual)
    - easy to understand charging lights - green - OK, red - charging, so easy
    - selectable current 300 or 650mA - can be used from smallest to biggest capacities
    - selectable voltage for Li-Fe and Li-pol (3,7 and 3,2V)
    - two separate channels, can charge two diferent batteries in the same time.

    Cons:

    - plastic seems a little too thin

    OtherThoughts:

    For this price it is a great cahrger, with accurate charging. 1st channel 4,15V AW17670, second 4,20V AW 18650.
    During charging it´s a little warm but nothing serious, still can keep in hand.
    Adjustable negative plate working fine, giving god contact with battery.
    LED is blinking every one second RED-GREEN durring charging, as I found internal chip (Samsung IC) is checking voltage.

    Bottomline:

    Ordered second one for my father as well. I´m happy so far, he will be too.
