Check the power supply and cable
Use a Compatible Power Supply
Using the original Bose power supply is recommended to ensure your speaker receives adequate power. In some cases—such as after a long period of non‑use—the speaker may enter protection mode and require the full 5 V DC, 1.6 A output to power on. Verify that the power supply you are using meets these requirements.
Verify USB Charger Power Rating
Check the text on the USB charger for its amp (A) or milliamp (mA) rating, as this varies between chargers, including those supplied with different Bose products. Chargers with higher amp ratings (up to the product’s maximum) will recharge the product more quickly. If the charger’s output is too low, the product may recharge slowly or not at all.
Refer to the product specifications or owner’s guide for the required power rating. Some products need a minimum of 1 amp to recharge, while many computer USB ports provide only 0.5 amps, which may be insufficient.
Always use a safety‑agency‑approved power supply that meets local regulatory requirements (such as UL, CSA, VDE, or CCC).
Check the USB Charging Cable
Disconnect and reconnect the USB charging cable at both ends, making sure it is firmly seated. After reconnecting, allow at least one hour for the speaker to charge.
If the issue continues, try a different USB cable to determine whether the original cable is faulty.
If you're using the charging cradle:
Disconnect and reconnect the speaker to the charging cradle.
The bottom of the speaker may not be connecting properly with the metal contacts on the charging cradle. Try removing the speaker and inspect the metal contacts. If you suspect the contacts may be dirty, disconnect the speaker and cradle from power, then clean the contacts using a cloth with a small amount of isopropyl alcohol.
When reconnecting the speaker, do your best to align the metal contacts on the bottom of the speaker with those on the charging cradle. This will ensure the speaker is sitting correctly in the cradle.Bypass the charging cradle.
Disconnect the charging cable from the charging cradle then connect the cable directly to the speaker. If the speaker begins charging, there may be an issue with the cradle. Determine the Warranty or Rapid Response status and see Service Options for details.
Reset your product.
To reset your product, power it off and disconnect the power cord for 30 seconds.
