I will charge it for 3-4 hours or until all lights are strong. It will kick the bucket or shut off 2-3 hours. In some cases it will just stop after a couple of melodies. It has great volume and is light and reduced however damn killing constantly, I scarcely even use it since I'm wiped out it. At times I'll have it on external the restroom during showers and it will not endure an entire brief shower regardless of whether I simply take it off the charger or its showing a full charge. What a misuse of cash.
