Well I have it now, it's on my desk charging an Efest 18650 IMR 2000 mAh battery, it says the battery is at 4.2 volts, but it's still charging, I'm not sure what it will display when it's done charging. I did find the unlabeled button to switch it to 1 amp from .5 amp. It doesn't have the LCD display that's on the version shown on the manual, it has the LED display, and I would have preferred the LCD display.
There's a little arrow symbol blinking up and down between the voltage readout and the battery symbol that shows the level, and I'm assuming it will stop when the battery is fully charged. IDK, maybe it will turn green or something, that would be nice. It should be able to charge at 1 amp on two channels but I'm not sure which ones, it doesn't say in the minimal manual it came with. It's pretty spiffy that I can charge my iPhone with it though.
