The original Bose power supply is recommended to properly power your speaker.  If the speaker is in protection mode due to a period of unuse, it might require a full 1.6 Amps to wake. Be sure the power supply you are using is 5 Volts DC and 1.6 Amps.

On the USB charger, there will be text that indicates the amp (A) or milliamp (mA) rating of the charger. This rating varies among chargers – including those supplied with different models of Bose products. The closer the amp rating of the charger is to the maximum amp rating of the product, the more quickly the product will recharge. If the amp rating of the charger is too low, the product may recharge slowly or not at all. Refer to the specifications indicated on the product or within it's owner's guide on for details.

Some products require minimum of 1 amp of current in order to recharge. Many USB ports on a computers can only provide a maximum of 0.5 amps of current. Be sure to use a safety-agency-approved power supply that meets local regulatory requirements (e.g. UL, CSA, VDE, CCC).

Disconnect and reconnect the USB cable at both ends, ensuring it is firmly connected. Allow at least an hour for the speaker to charge after the connections have been reestablished.

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.
