Make sure you'll never have an empty battery and charge your iPhone with an Apple iPhone 7, 6, 5, or SE (2016) charger. These iPhones all have a Lightning charger, and they can't fast charge. Choose a separate USB-A charger if you already have a lot of Lightning cables. Choose for a charger with Lightning cable if you also want a new cable. Sturdy nylon cables last longer than a standard plastic cable. If you want to charge 2 or more devices at the same time, choose a charger with multiple connectors.
