Ok, I have a Ego-c Twist 1100, I also have 120mAh and 420 mAh chargers.
My ego charges with solid red light on the 120mA, but with the 420mA it blinks red/green constantly, as well as the button LED constantly flashing like the charging process is restarting constantly.
My girlfriends vape pen charges with solid red light on both chargers, until full.
I also used her dad's 420mA charger on my Ego-c and it stayed red till full an turned green.
Could it just be my charger? Or what, the different reactions between pens/chargers is confusing.
