what does it indicate when both the blue light and red light are lit?

Blue & Red means you are both taking power in to the unit and potentially sending power out. I've had mine plugged into the wall & my iPod fairly often, and it seems to wok OK that way...

As far as I can tell, it only happens when I am charging a device while charging the yubi portable at the same time. I only did it once out of curiosity, but I haven't noticed both lights on at once at any other time. Hope this helps!

The light is a bit hard to see. You can see the red or blue light in the outline of the power button.

The lights are all on at the same time. There are, however, three different light intensity settings.

Yes, it should be illuminated in blue. It sounds like the backlight on your's may be broken.

Don't quote me on this, but I think red means the device is grounded. So you do want both lights on.

Yes, there is a blue light that lights up when there is an animal or a person in its area. If the light doesn't go off it probably means the batteries are dead.

There is one blue light when the device is plugged in. There are not individual lights for each port.

It is simply two LED lights, one blue and one red. When the battery pack is charging, both LEDs are on to let you know that it is charging. And when it is connected to charge something, the blue LED turn on to indicate that it is charging, and still have power.

In the middle over the screen. A blue light should come on when it's working.

It means the device's charge is low. Plug it into a charger. It chargers very fast. When the red light turns blue, it is fully charged

There are different light brightness settings, one of which is the off position.

The part that plugs into the outlet has a blue light, the back light of the display is red.

No, if you lift the mouse up, and be careful, look and you can see the blue light. The top light is for low battery. Ciao . . . Sal

There is a little LED light that changes to blue when fully charged. The unit very simple and works.

Blue light means its charging a device. Red light means it no longer holds a charge, and you need to re-charge the battery.(Although my device has a red light when plugged in to re-charge) Not sure about how to keep it from wasting battery? I guess do not plug it into device until you need to recharge.
