Key takeaways
- LED meaning is charger-specific—read your OEM charger card/manual, not a universal color chart.
- Steady red often means charging, but never-finishing, heat, odor, swelling, or damage → unplug and contact support.
- Use only the original/recommended charger. Do not leave a hot or odd-smelling pack on “long soak.”
Normal vs stop
- Normal-ish: red during charge within the manual’s expected window, charger and pack stay cool to the touch.
- Stop: excessive heat, smell, swollen pack, damaged cable, or red after far longer than the manual allows.
Safe steps
- Confirm OEM charger and dry, undamaged outlet.
- Fully seat the charge plug.
- If abnormal, unplug; do not keep forcing charge.
- Support with model/SN and charger label photo.
