Product will not turn on
Do not charge the speaker while it’s wet
The SoundLink Max is waterproof (IP67-rated), but it won’t charge if moisture is detected in the charging port. You’ll see a white and amber flashing Power light if this happens. Wait until the speaker is dry before charging.
If the speaker has been in extreme temperatures, let it return to room temperature first
If the speaker is too hot or cold, wait until it reaches room temperature before using it.
Charge the Speaker
Use the 3A USB-C wall charger and USB-C to USB-C cable that came with your SoundLink Max. If the battery is very low, make sure you’re using the correct charger, or the speaker might not charge.
Charging Time
It takes up to 5 hours to fully charge the battery with a 3A/15W charger. A full charge gives up to 20 hours of use. At maximum volume, the battery lasts about 3 hours. Charging time and battery life can vary based on the power source, music, volume, and if you’re charging another device.
Check if the speaker turns on when plugged in
If it turns on with power but not on battery alone, see the section on “Product does not power on with battery power.”
Check if the power outlet works
The speaker should make a tone when plugged in. If it doesn’t, try plugging something else (like a lamp) into the outlet to see if it’s working.
Try a different USB cable
Use another USB cable to see if the original one is the problem.
