How to Use

1. For phones and tablets with a display: Note that 100% shown on your screen does not always mean the battery is fully charged. Typically, after an additional 10–50 minutes of trickle charging, the battery reaches its true full capacity. The adapter will auto-disconnect only once the genuine full charge is detected.
2. If the adapter disconnects early (around 80%): Go to your phone's Settings → Battery → Charging and turn off "Battery Optimization" to allow a full charge cycle to complete.
