New vehicles boast a range of device charging options including DC, AC, USB and wireless. DC, the oldest electrical current, is still used by some radar detectors and car accessories but requires a 12-volt adapter and cable to power most smartphones. AC plugs are the same as a household wall outlet and are commonly used to charge laptops or car camping gadgets.
USB ports come in two varieties, USB-A and USB-C, and operate at varying levels of output and charge rate. Both ports require a cable to charge devices or connect them to onboard infotainment systems. Wireless charging takes up more real estate but cuts the cable clutter. Just slip your compatible smartphone onto the charging pad and be on your way.
