Is there some way to know how much power has left after I charge my device? I do not see led indicator or something like it.

Indeed there are four blue LEDs on the top of products, near the two USB sockets. When you click the button, they will show how much of the power left. e.g 4 LED means full of power. 3 LED means 75% power left.

This is just a guess, but LED light technology is such that the light will still work even if there is just a little power remaining. There just might not be enough power left to charge your device. It's possible that you just have to re-charge your battery by plugging the micro-USB cable into the battery and connect the other end to a power source. If that doesn't work, contact the manufacturer.

I don't think so, there's no indicator except the light which seems to flash fast most of the time when charged but not all of the time, perhaps that's an indicator but it doesn't say so on the instruction sheet which is pretty uninformative.

No it doesn't have a light to indicate the level of battery left, you'll know it's being charge or charging when the it lights up. Other than that you are on your own! But the battery last long enough to fully charge iPhone 5s

U don't because it does not have an indicator light. So what u do is leave it around 4 to 5 hrs to make sure u have ample amount of charge.

Yes, in the upper right corner there's a battery icon that indicates the remaining charge - it's on all the time.

Mine has a red light that comes on and stays on while charging. I will update when it's done charging to let you know what it does.OK, after charging the red light went off. At that point I disconnected from the charger and reconnected it, the light came on for a second and went right back off so it looks like you're fully charged. Hope this helps and enjoy!!

No LED for illuminating anything, however there are LED's on the Charge Controller that let you know the charge status.

LED indicator turns green under the USB port when full. I don't usually fully drain the battery but I would say two or three hours to top off. Power switch will go red when it's time to charge. Terrific light!

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

From what I understand from reading the owners manual, that indication is the chargers way of telling you that the battery is very discharged and is only at about 25% of its capacity. The LEDs are supposed to blink, not light up solid, as the charger is charging. If there is nothing wrong with the battery, the charge level should start going up after a while and in a few hours, the LEDs should read at 100% (solid, not blinking, red, red, yellow, green LEDs). I hope this helps you Mary! Michael R

Sharon, When you press the button you should see all 4 LEDs lit up. Please note, it does take longer to charge than a phone. It will take probably overnight to completely charge.

From low battery reminder to fully charged, I believe it's about an hour and a half. Red LEDs light up in the dock while charging, then go back to blue once complete. The LEDs are bright enough, I can see the status from across the room.

I just received mine. I am still letting charge to full power. The light is still blinking so it is no up to full power yet.

Too bad. I am like a few others and would appreciate some sort of light to inform me that it is 1. charging and 2. finished charging.

I am not totally sure, if I haven't charged it in a few weeks, I would probably charge it up again. However, the indicator lights make it very obvious what the status is (whether fully charged or not, how much charge is actually left)
