Fully charged in about two hours.
Charging can be completed in about two hours, you can play while charging, and you can use the data cable of most Android phones. I've been listening for four or five days since it was fully charged, maybe eight or nine hours, and there's still power. After listening for a long time, I can't feel the heat at all. This shows the utility of cute little things.
The Elvis Bluetooth speaker is charged from zero to full, takes three hours, and can be fully charged
