Your phone will show that it's charging... Ex: when my iPhone is plugged into it, the battery icon on my iPhone shows the lightning volt icon.

It would appear that there is a constant power connection. My iPhone is able to charge when my car is off.

On mine it shows a battery icon. When it begins charging that icon is empty and flashes. When it's fully charged, the icon is full and ceases to flash. Hope this helps.

There is no way to know when it is totally charged. I just charged it up overnight and it held a charge for a long time.

there is no indication while you are away from the charger how much charge is left. I recommend buying a second one so you always have two (one charged).

If being charged by AC there is an auto shut off. If plugged into a DC power source you have to monitor the charging by eye.

No.There is a charging light as you charge. In addition, a charging indicator shows you the bettery power at any time.

You plug it in...and wait for the red light to start blinking. Once it does, turn on the main power button. The light on the chord will then turn red and you will know your charging.

Press the button on the top of the device and it will wake up the screen to show you the charge level. This device can not interface with your PC via USB and will only use it to charge.

Simply plug the USB cable into the device and the other end into the USB port on your computer and it will light up to indicate that it is charging and the light will let you know when it is fully charged....easy and charges fully in about 4 hours....

It has a light to let you know when it's done charging. I usually left it plugged in overnight, but no amount of charging was ever enough to give me more than 10-15% battery power. I just pitched it and bought the PowerAdd 5200mAh. It was only $13, and it gives me 1+ full charge.

Yes! It will tell you it's fully charge when the battery is 100%. It will also tell you to unplug the device.

To really see if the battery is really "full", I'd unplug the AC charger, wait 30 seconds, then push the "battery test" button again. If it still reads "99%", the battery is really charged. If it goes to "65%" or such, then it needs more.I base that on having got one and when I first plugged it in, it instantly began flashing "FL". However when I unplugged it the display instantly went to 10% or such showing that the battery was resisting the charge and the "FL" reading was false (just coming from the chargers power only while it was plugged in). So don't be fooled into thinking it's full that fast, yet 5 hours is a lot more than under 5 minutes (where it may have taken in some power, but it may still need more).
