The LED on your Blast wireless charger tells you the sensor’s charging status at a glance. Plug the charger into a USB port and place the sensor face-up on the charger logo to begin.
LED Indicator Colors
- Red LED — The charger is not active. Either the sensor isn’t on the charger, or it’s already fully charged.
- Blue LED — The sensor is actively charging.
- Green LED — The sensor is completely charged.
Once your sensor reaches a full charge, it stops charging and enters standby mode. To resume charging, the battery level needs to drop below 93%, and you’ll need to remove the sensor from the charger and place it back on.
FAQ
What does a red LED mean if my sensor is on the charger?
It typically means the sensor is already fully charged, or it isn’t seated on the charger correctly — make sure the sensor logo faces up and sits centered on the charger.
Why isn’t my charger doing anything even though the sensor is on it?
If the sensor is already at full charge, the charger goes into standby and shows red until the battery drops below 93% and you reseat the sensor.
