This charger came with no instructions. The light is blue--what color does it become when it is charged?

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.

When it's charging, the color is violet and I guess it's around 80-100 percentage, it'll be blue..roughly it'll take around 4+ hrs to charge the battery. This is how mine works so I'm not sure about the color, but you can make sure by inputting it to your device and see the battery's percentage.

It should turn pink. You have to match the copper with the gold like thing.

When you plug it in with a dead battery, the light should be red., When it is done charging, the light will be green. If your charger does not do this, you have a bad charger. I had bought a lower priced model, and it did not work. So be sure to get a quality charger.

Flashes Blue/Green while charging, and becomes solid blue when fully charged. I wondered the same thing.

I can only speak for mine but it has a light at the top that is purple while charging and blue when its done charging. From my experience it takes longer to charge in this charger than it would if its in your phone and hooked up to your regular charger, hope this helps.

There's a female micro USB port on the top. You just plug any Micro USB charger cable into that and it will start charging. 4 blue LEDs indicate the charging status and all 4 will be lit when it is fully charged.

Some chargers change color from red to green (or green to red). Others just turn off the light altogether. If it has been charging a reasonable period of time, take out the battery and put it in your camera. Turn the camera on. If it's showing the "full battery" signal, then you know that your charger just turns off when it's finished.

When you first connect the battery the light turns red to show its connected properly. Then when you plug into the wall it flashes blue. When it is done charging it turns solid blue. It takes a long time, but worth it if you charge them ahead of time and take the batteries with you. I charge them overnight. Hope that helps.

When it's charging it's red, when it's charged its blue. Either you plugged it in wrong or it's defective.

this is a known issue. you need to place the battery in the charger and then unplug and plug the charger into the wall outlet. the light should go solid blue (charging). if you don't do this the blue light will probably stay flashing and will not charge. i learned this by calling Hoover directly.

No, in fact it doesn't charge anything... It didn't turn on. But it will however take a charge for 4 hrs and all the blue light will be on (meaning is fully charge). But will it charge other things? HELL NO!!!

When the unit is plugged into the wall (for charging) the light will be red. When it is fully charged, it turns blue. At this point you can unplug it and carry along with you. When you plug a device into it for charging, the light turns on and is blue.

The light should turn red when it's plugged in. It will turn blue when fully charged.

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.

There is an LED light underneath the cap that shines through. During the charging process it will light up red, and blue when 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)

Charger light changes from red to green, IIRC. Don't have it with me right now. *Might* be printed on back of charger...

A red light comes on when charging. When fully charged the light goes off. It doesn't change color.
