Anker power banks use blue lights to signal how much power they have left. Sometimes, users might see a green one on their power bank instead.
If you haven’t seen this before and are worrying about it, or just want to know what it means, keep reading. This guide is all about the green light on an Anker power bank.
You can also watch my video about this topic. There, I explained in detail what a green light on an Anker power bank really is.
When the trickle charging mode is activated on an Anker power bank, it would show green light. This mode is designed to charge small appliances like earphone, etc..
Anker Power Bank Green Light – Explained
Let me get rid of any worries first; the green light isn’t anything problematic. It’s not a sign that something is wrong with the device. But, if not that, then what’s the about?
These power banks are considered top-of-the-line because they’re more than regular battery backups. They have a bunch of extra features too for user convenience.
One of those features that I find super handy is the trickle charging mode. That feature is what the green light you’re seeing is there for, and it changes how the device works.
When trickle mode is on, one of the four blue lights on an Anker power bank will change to green. Here’s the page from the device’s manual that explains more about this feature:
Lots of power banks have a common problem charging less powerful devices like smartwatches or fitness bands. They just stop working entirely while charging them.
This happens because those less powerful devices don’t draw as much voltage as the power bank is meant for. That leads it to believe it’s not charging anything at all, so it stops working.
I used to get super annoyed with this on my old power bank. My wireless earbuds would randomly stop charging and I had to keep adjusting them, which wasn’t very convenient.
Trickle mode is to prevent situations exactly like those. It’s a mode that lets the power bank output weaker voltages for low-power devices like AirPods, smartwatches, and more.
You’re seeing the green light because that mode is on. While it’s on, your Anker power bank will be outputting lower voltage than usual, so disable it when necessary.
To turn this mode on, all users have to do is press the button twice. Then the green light will replace one of the blue lights like in the picture below to let you know that trickle mode is on.
Repeat the same thing to turn the mode off when you want. Press the button twice, and the green light will disappear. That’s when you know trickle mode isn’t on anymore.
I use this setting so often because my devices are always running out of power on busier days. Like when my flashlight turns off when I’m working with my tools.

Trickle mode lets me charge devices like flashlights and everything else I’ve mentioned so far. The Anker power bank doesn’t disconnect due to low power draw when it’s on.
Let me show you an example of it by putting my Olight flashlight on charge. When I use other power banks without trickle mode to charge this thing, it doesn’t work.
Since it’s a low-power device with only a 3.7v battery, the Olight flashlight doesn’t have much current draw. With trickle mode, that’s not something I have to worry about.
By now, you get the idea of what trickle mode is and why it can come in handy. The main point of all this was the green light though, so let me get back to that.
It’s not a warning indicator, and you can easily get rid of it by double-tapping the button on your Anker power bank. Remember to use it when necessary!
