What do the lights mean on my ACR Bivy Stick?

When the device is plugged in and charging, the LED light next to the power light will flash as it is charging. If the device is powered on, you'll know it is done charging when the LED light changes to a solid green light. If the device is powered off, the LED light will turn off when charging is complete.
