Why does my Anker charger's LED light always turn blue once plugged in (with and without a battery) and only sometimes charges batteries?

The blue light indicates that there is power to the charger. If the light does not turn purple(pink) then the battery is not charging. It is easy to get the alignment off when putting the batter in and then the batter wont charge.

Blue means that either nothing is plugged in or that the plugged in battery is fully charged. If the device is functioning properly, it should turn purple when it is actively charging a battery.

The batteries have an internal microchip that tells the charger to come on and when to turn off after a full charge. Blue means the battery is telling the charger it is full. If your battery isn't charging then perhaps its near the end of its life or is defective. The charger is always blue when plugged in with a full battery or no battery at all. Only turns purple/pink when charging. Check your pins aren't bent on the charger also.

the plastic on the bottom of the charger changes color. it turns blue. that is when battery is fully charged.

Call Anker on the number shown on the little instruction booklet that came with your charger. I have not heard of a blue flashing blue light but if the phone is charging the light color is a moot point. (maybe they ran out of green lenses at the factory)

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.

When the light is either red or some shade of pink/purple the battery is charging. When the light goes blue the battery is charged. I believe that once the light turns blue the charger stops charging the battery, but the light remains on. The blue light never turns off.

When I place battery in charger it is red. When charged it turns blue and battery comes out. Mine does not flash.

Is it blinking all the time? or just when you connect a device? My light is blue steady even when I connect a phone to charge.

I typically charge mine overnight and the light changes from purple to blue.

When you stick an uncharged battery in there, the light should turn red. It turns progressively more blue as it fully charges. When it is fully charged, the charger will be blue.

There are three LED lights on the charger. as the battery in the charger charges, first one LED will light, then the second LED will light, then the third LED will light.When all 3 lights are lit, the charger is fully charged.

After the battery is fully charged the light will turn blue. It is when you charge the battery in the charger dock. But if you charge the battery via the USB port, the light will be always blue and you can see if the battery if fully charged in your phone indicator.

The light will turn blue when its charged! And if you notice, the charger gets a bit warm while charging but when it has finished charging the battery it cools right back down! Won't fry it st all!!

Mine does the same thing. It is charged when I unplug it later. I wish the LED indicator would stay on.

Maybe you have the conections inverted, try to switch the + and the - poles and try again, when is charging the blue led does flash and if the poles are inverted does not light

There is only one light in this charger. When you plug it into the device, it will turn red and then it will change to green when charged. Check the side once you plug it in. Took me a couple of looks to make sure it was functioning - I did not think it had a light myself.

There's a blue light that comes on when it's charging some device. If it needs to be charged, that light doesn't come on.
