Why does my LENRUE A2U speaker only work when plugged into a power source and shut off immediately when the Type-C cable is removed?

Based on your description, it appears the internal rechargeable Lithium-Ion battery in your LENRUE A2U is either failing to hold a charge or is not receiving power from the charging circuit. Since the device works while plugged in, the internal components are functional, but the power delivery system is failing to transition to battery power.Please try the following troubleshooting steps:Verify Charging Status: Connect the speaker to a power source using the Type-C cable. Check the LED indicator; it should typically show a red light while charging. According to the manual, a full charge takes approximately 3 hours. If the light never changes or turns off immediately, the battery may be defective.Check the Power Source: Ensure you are using a functional USB wall adapter (5V). Sometimes charging via a computer USB port does not provide enough current to revive a deeply discharged battery.Inspect the Cable: Although the speaker works while plugged in, try a different Type-C cable to ensure the current is sufficient to actually charge the battery rather than just powering the unit.Reset the Device: While not explicitly detailed in the basic manual, many Bluetooth speakers can be reset by holding the power button for 10-15 seconds while unplugged, or by checking for a small pinhole reset button (if available) on the bottom or side.If the speaker continues to shut off the moment it is unplugged after a 3-hour charge, the battery is likely dead. Since this is a "new" unit, we recommend contacting LENRUE customer service through your retailer's support channels to utilize your limited warranty for a replacement.
