Before using Power ™ Magsafe External Battery for the first time, please fully charge it with a Lightning to USB cable with a 20W or higher power adapter.
- Plug one end of a Lightning to USB cable into the Lightning connector on your MagSafe battery.
- Plug the other end of the cable into a 20W or higher USB power adapter, then plug the adapter into a power outlet. The status light on your MagSafe battery pack will remain on for approximately 8 seconds.
While the Power™ Magsafe External Battery is charging, the status light may flash. If it flashes green, the battery is fully charged. If it is flashing amber, the battery may need more time to charge.
Using an adapter other than 20W or higher will result in slower charging.
