Thank you for bringing this to our attention. Here are some troubleshooting steps for our JBL Flip 7. Start by unplugging it and holding the Power button for 30 seconds to see if it unlocks. If it still won't charge, try using a different cable, adapter, and wall outlet, and ensure the charging port is clear of any debris or dust. We can also perform a factory reset by turning on the speaker and holding the Volume + and Play buttons simultaneously for 5 seconds or until the unit powers off. Once it reboots, ensure you "forget" the device in your phone or tablet's Bluetooth settings before attempting to pair it again, keeping in mind that this process will wipe all previous settings and pairings.
