found this while reading about a Ninja Blast portable blender that wont turn on. I figured I'd toss this out there as other has seen this same issue.
According to manufacturer, there are four reason the device will not turn on. When first troubleshooting, the LED will flash to tell you an issue.
If the LED flash red the battery is too low to power on. Flashing yellow indicate the jar isnt properly aligned with base. Flashing orange indicate the blade are jammed with an object. If the battery itself is going bad the voltage will read low and you will need to replace the 18650 cells.
