Battery charger with blue light

[Kkit]

My Audew Battery charger blinks with a blue light when I plug it into the wall to charge it. What does this mean question can I fix it? Or is the charger to be thrown away?

Is this a charger for drone batteries?
What model is the Audew charger?

The only Audew battery chargers I find in a web search are for automotive batteries.
