Can I use a USB-C phone charger to power my Nintendo Switch?

You can use a USB-C charger with your Switch, but you need to make sure it delivers enough power - the Switch needs at least 5V/1.5A for handheld mode, or ideally 15V/2.6A if you want to charge while playing in docked mode. Most modern phone chargers that support USB-C will work fine for handheld charging, though they might charge slower than the official charger. Just avoid super cheap knockoffs since the Switch can be picky about power delivery, and stick with reputable brands when possible.
