Learn about the LED lights that power banks have and what they mean. The blinking lights signify different charging stages, depending on how many LEDs there are.

The standard setup is 4 lights, each of them signifying 25% of charge. But some power banks can have 3 or 5 lights instead of 4. Regardless of the number of lights, they all have a very similar purpose.

Sometimes, portable charges can also have lights of different colors: blue, green, and red being the most common.
