How do I know when my Fitbit Flex is charged?

As the Fitbit Flex charges each of the Flex’s LED indicator lights will pulse to show the battery level every few seconds. There are 5 lights on the Fitbit Flex so each one indicates 20% of battery charge.

To fully charge the Flex, it should take around 3 hours. When it’s charged, all 5 indicator lights will blink.

I will upload a video shortly showing how the Fitbit Flex appears once fully charged.
