How long does it take for the Here Buds / portable charging case to fully charge?

The Here Buds will be charged up to approximately 25% when placed into the charging case for 15 minutes.

It takes up to 1 hour for the Here Buds to fully charge while in the case. While the Here Buds are inside the case and the case is not charging, the LED light on the outside of the case will turn solid green to indicate that the Here Buds are fully charged.

It takes around 3.5 hours for the Here Buds and case to fully charge when the case is connected to a power source via USB and both are completely dead. Though both will charge simultaneously, the buds will charge in about an hour and the case will continue to charge for an additional 2.5 hours until full. While the case is plugged in, the LED on the outside of the case will turn green to indicate that the case and Here Buds are fully charged.
