From the iPhone 15 onwards—or until Apple offers only wireless charging—Apple has replaced the iPhone's Lightning port with a standard USB-C port so you need a USB-A to USB-C or USB-C to USB-C cable. The new iPhones ship with the correct cable so you don't need to go looking for a new one unless you require a spare—and, let's face it, most of us need several. Check out PCWorld's list of the best USB-C cables.

Apple still includes a cable in the box with all new iPhones whether they have Lightning or USB-C. But you can never have enough charging cables, right?

Older iPhones (before iPhone 15) require a Lightning port on one end. If you need a spare, make sure you buy a USB-C to Lightning cable that's certified Made for iPhone (MFI).

Anker makes several of our recommended iPhone chargers, and its MFI-certified USB-C to Lightning cable is a little cheaper than Apple's own cable and is twice as long. Anker has a bunch of USB-C to Lightning cables in various lengths and colors on its U.S. Amazon Store and at Amazon UK.

We also rate UGreen's USB-C to Lightning iPhone charge cables. For more detail, read our roundup of the best Lightning cables.

Yes, you can safely use a laptop charger with a higher wattage as the laptop will only ever draw the amount of power required at the time. If your laptop was supplied with a 35W charger it will never draw more than 35W unless being fast-charged, so you can use a 65W, 90W or higher charger. To reassure you even further, you can safely charge your 5W AirPods with a 240W charger if you wish.

If the charger has multiple ports that extra juice will mean you can charge other devices at the same time.
