Yes. Apple’s MagSafe technology is backward-compatible with the standard Qi wireless charging specification, so you can charge any iPhone or other Qi-compatible wireless device using a MagSafe charger, although you’ll be limited to the slower 7.5-watt charging speeds. Note that older iPhones also won’t attach magnetically to a MagSafe charger, which may limit compatibility with certain charging stands that are designed to hold the iPhone in place while charging.
