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

Pros:
- compatible with most of LiFe and Li-ion batteries - 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
Other:
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.
