Do I need USB-C on a surge protector?

Only if you plan to charge phones, tablets, or USB-C-powered laptops directly from the strip. USB-C with Power Delivery (often 20W or higher) saves a wall wart, but reviewers note that the USB circuitry is sometimes the first thing to fail on budget strips. If you charge expensive devices, a dedicated wall charger plugged into the strip can be more reliable long-term.
