Good to know

Before use, check your device's original power rating (voltage and current) and select the matching output setting and correct polarity tip on the adapter, as using the wrong voltage can damage sensitive electronics. This adapter typically ships with multiple interchangeable connector tips to fit different device types — confirm the tip size matches your device's power socket.
