Symptoms
- Some ports charge devices while others don't
- No ports work even though the station is plugged in
- Station's indicator light is off
- Worked fine until recently, then stopped charging anything
Likely causes
- CommonIndividual port has failedMulti-port stations often have ports fail independently of each other.
- CommonShared power adapter can't supply the total demandCharging several devices at once can exceed what the station's adapter provides, slowing or stopping some ports.
- PossibleMain power adapter or cable to the station has failedIf the whole unit is dead, the incoming power supply is the likely cause.
- Less commonInternal circuit board faultPhysical or electrical damage can disable the whole unit.
What to do
- Test each port individually with the same device and cable to identify if only certain ports have failed.
- Reduce the number of devices charging at once to see if performance improves, which points to a shared power limit.
- Check that the station's own power cable and adapter are firmly connected and undamaged.
- Try a different wall outlet for the station's main power supply.
- If the whole unit shows no indicator light and no port works at all, the internal power supply has likely failed and the unit should be replaced.
