Slowly charge your Apple devices with the Apple 12W USB charger. This 12W doesn't have a fast charge function, so you need about 2.5 to 3 hours to charge your iPhone. Go for a 20W fast charger and fully charge your battery in 1.5 to 2 hours. A cable isn't included with this charger. Purchase a sturdy nylon cable with it, which lasts longer than a plastic cable. For your iPhone 15 or new iPad, use a USB-C cable. Connect your iPhone 14 or older and older iPad models with a Lightning cable. Note: the cable that's included with your iPhone in the box only fits on fast chargers, so it doesn't fit on this charger.
