The new Olight flashlights that are 21700 powered come with the new MCC 1A/1.5A/2A charger, distinguishable by the red face. If you try to charge it with an old MCC 1A charger you will get the red with small bursts of green as shown in the video (some too short to be seen here). The 1A charger (in this case) so upsets the 20A USB power block that MCC 1A's not even connected to a light will flash red & green.
I don't fully understand what is going on, just FYI for now.
The light here is a second generation Warrior X Pro.
