How do i know if it is charging? Mine shows only two lights no matter how long it has been plugged into USB supply. - well over 12 hours.

I did the same thing. I found a review that explained it. To charge the charger you need to plug a mini usb into the side of the charger to charge it. It will charhe fully in a few hours. I didn't see the mini usb port until I read the review.

I have it plugged into the small usb on the side of the device for hours and it still isn't charged.

I plugged mine in for the recommended 8 hours, but the light remained red. As the directions were firm not to leave it plugged in longer, I unplugged it. Did anyone else's light change from red to green when charging it? It works great so far!

Is the blue light on? That would ensure that you have a power source. Mine charges just fine. It takes about 5 hours, with the phone on.

the light should flash on and off while charging I am pretty sure. I did use a powered usb hub to charge mine.

You should not have to charge it that long.There must be a proablem with it.2 hrs worked with mine.Try another plug otherwise send it back

The light goes out when charged. If completely discharged, it takes around 3 hours to charge.

When I charge mine, I plug it in & turn both power buttons on. When all three lights are bright I then considered it charged.

It varies based on the power of the charger you are using and quality of cord. It's a long time 6+ hours if you are below 2 power lights.

I charged mine for 12 hours the first time and mine worked perfectly. You might want to make sure the battery connection is good.

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....

I don't know if yours is like mine but one of the blue lights is fainter and doesn't work very well. It doesn't mean it isn't charging. I got 10 phone charges out of it plus 2 tablet charges when camping :)

Mine was @ 2% the other night and within an hour, was fully charged. Now that will depend on the quality of USB you're using also.

It usually takes several hours to charge. I charge it over night. You'll know it's charged up after the red led (light) shuts off.

I think you should return the charger. Mine works for 20 to 30 min after charge. I don't remember the light thing as I haven't used it since late summer.

It takes mine a full night to get close to full. About 11 or 12 hours will charge it 100%. Try using a different charger and cable and charging it again. If it charges correctly with the new charger, replace your charger. If it still doesn't, replace the Lumsing.

That is too long, I don't pay close attention but I am thinking 3 hours gets me fully charged or close to it. I use a variety of different wires depending on where I am and have never noticed that it takes particularly long...particularly to get 2 or 3 lights.

I had the EXACT SAME experience and before i figured it out I thought it had died on me. I started the whole Amazon return process and then realized, like you said, that it needs to "charge" for a bit after plugged in. I have to say that it's kind of annoying but I love the light so much that i"m willing to look past that> Maybe it's a hint to me that I need to get my son a power strip so that he doesn't have to keep unplugging things to charge items. =) Hope this helps. ~ Nikki
