Is it safe to use a USB-C laptop charger on your phone?
Using a laptop charger for your phone can be a convenient option, but safety precautions are essential. While a laptop charger may have higher wattage, it will only charge a phone at its rated input, usually between 18W and 20W. Users should prioritize certified chargers to avoid risks such as voltage spikes from poor-quality devices and cables. Always ensure chargers and cables meet safety standards to protect both the device and its user.
