Answer: 1. After you receive the package, charge it for 30 minutes, then turn it on (there may be no power to turn it on) 2. Observe whether the red light can be turned on after plugging in, and if the red light cannot be turned on, please contact us immediately. The red light can be on, please contact us in time, we will tell you how to start the process 3. After plugging in, if the red light continues to flash, please replace the normal 5V-2A charging head Question2: The speaker is used less than 8 hours? Answer: 1) We have rigorously tested and uploaded Hotel California's lossless sound quality memory card, and it can be played for about 3 hours at maximum sound. If the maximum sound playback time reaches this range, the speaker is normal and there is no problem with the battery. 2) In addition, different sound sizes and different songs will directly lead to the duration of the speaker. Especially for songs with stronger bass, the power consumption of the speakers will increase significantly. 3) Therefore, if it is only ordinary music with weak bass, the loudest sound we tested can reach 4 hours. Question3?: Can't charge normally?? Answer: Scenario 1---I just received the package, but I can't charge when I use non-quick charge plug. It can be the product itself. Please contact customer service for the reason for the failure. Scenario 2---After using for a while, the product suddenly fails to charge. Please check if the charger plug you are using is a non-fast charging plug. If you use a quick charge plug, the product cannot be charged normally. Please switch to a normal outlet immediately. If the normal charging socket is used as usual and there is no improper behavior (water in the socket, moisture, electric shock, surge impact, artificial damage to the socket chip, etc. ), the product may be damaged normally. Please contact customer service immediately. Question4: The button does not work? Answer?: Check the phone model and music player app. Some mobile phone models cannot directly use the speaker switch key to control the pause/play function. It is recommended to change another cell phone model or music player app to try again. Important: If you have any questions, please contact customer service. Please don't random bad review or dispute, we will solve your problems. Thank you very much for your kind understanding!!!
