01The charger the iPhone 16 uses
The iPhone 16 uses a USB-C charger, and for fast charging that charger needs to support USB Power Delivery (USB-PD). Apple says a 20W or higher adapter gets it to about 50% in around 30 minutes.
Apple ships the iPhone 16 with a 1 m USB-C charge cable and no power adapter. Any USB-C PD adapter you already own from an iPad, MacBook, iPhone 15 or a recent Android phone will work. Old USB-A cubes and Lightning cables are the only things left behind. More on that in is it safe to use a non-Apple charger.
| How you charge | Max speed | Adapter you need |
|---|---|---|
| USB-C cable | About 50% in ~30 min | 20W+ USB-C PD |
| Apple MagSafe Charger | 22.5W peak (iPhone 16) | 30W+ USB-C PD (15V/2A) |
| Qi2 25W charger | Up to 25W (Apple's spec) | Whatever the charger asks for, usually 30W+ |
| Qi2 15W charger | 15W | 20W+ USB-C PD |
| Basic Qi pad | 7.5W | Whatever the pad asks for |
0220W or 30W: which adapter to buy
For cable charging, 20W is the sweet spot. Apple's own fast-charge figure (about 50% in around 30 minutes) is based on a 20W adapter, and the phone controls how much power it draws. A larger brick is safe, but by cable it won't change much.
MagSafe is different. Apple's MagSafe Charger only runs at its faster rate when the adapter behind it supplies 30W or more. Plug it into a 20W cube and you're back to slower charging. That's a common reason a new MagSafe charger feels slow.
20W USB-C adapter
- Full wired fast charging
- Small and cheap
- Holds MagSafe back to slower speeds
30W+ USB-C adapter
- Runs faster MagSafe charging
- Same wired speed as 20W
- Multi-port models charge AirPods or a watch too
03Speeds across the iPhone 16 lineup
The adapter advice is the same for every model, but wireless speeds differ. The bigger phones get the full 25W from Apple's MagSafe Charger; the smaller ones peak a little lower.
| Model | MagSafe max | Qi2 | Adapter for MagSafe max |
|---|---|---|---|
| iPhone 16 | 22.5W peak | Yes | 30W+ |
| iPhone 16 Plus | 25W | Yes | 30W+ |
| iPhone 16 Pro | 22.5W peak | Yes | 30W+ |
| iPhone 16 Pro Max | 25W | Yes | 30W+ |
| iPhone 16e | No MagSafe | No magnets, 7.5W Qi only | N/A |
The iPhone 17 has its own charging quirks, including Apple's 40W Dynamic Power Adapter. We cover it separately in what charger does the iPhone 17 use.
04MagSafe and wireless on the iPhone 16
Three things decide your wireless speed: the charger, the adapter behind it, and the case. A certified Qi2 or Apple MagSafe charger plus a 30W adapter gets the fastest result. A magnetic pad that isn't Qi2 certified will hold the phone fine but usually charges at basic Qi speed, 7.5W, which is perfectly good overnight. Our Qi2 vs MagSafe explainer has the details.
Use a MagSafe-compatible case so the magnets stay strong, and avoid thick rugged cases or anything with a metal plate. If wireless charging stops or stalls, work through MagSafe charger not working.
Stands and pads that keep the phone aligned, and a case that keeps the magnets doing their job.
05Charging on the go and battery settings
Away from the wall, the rule is the same: USB-C with Power Delivery. A car charger or power bank with a USB-C PD port of 20W or more fast-charges the iPhone 16 by cable. Magnetic power banks are convenient but slower and less efficient, since some energy is lost as heat. Our magnetic vs regular power bank comparison spells out the trade-off.
At home, you can let iOS look after the battery. Open Settings > Battery > Charging to choose a Charge Limit between 80% and 100%, or leave Optimized Battery Charging to hold at 80% overnight and finish just before you usually unplug. Neither setting affects how fast the phone charges when you're in a hurry, only where it stops.
MagSafe in a car on a sunny day is the classic slow-charging setup. iOS pauses or slows charging when the battery is warm. A cable charger and a vent mount keep things cooler.
06Cables and adapters worth owning
Keep the cable from the box at your bed, buy a second USB-C to USB-C cable for the bag, and get one adapter of at least 30W if MagSafe is in the picture. The iPhone 16's USB-C port can also charge AirPods or an Apple Watch from the phone in a pinch.

Questions people ask
Can I use a 20W charger on an iPhone 16?
Yes. A 20W USB-C PD adapter fast-charges the iPhone 16 to about 50% in around 30 minutes by cable. It's only too small if you plug Apple's MagSafe Charger into it, which needs 30W or more for its faster speed.
Does the iPhone 16 come with a charger?
No. It comes with a 1 m USB-C charge cable but no power adapter. Any USB-C adapter with USB Power Delivery works.
Can I use a higher-watt charger, like 65W, on my iPhone 16?
Yes, it's safe. The iPhone negotiates only the power it needs, so a 65W or 100W USB-C charger works. It won't charge much faster by cable than a 20W adapter.
How fast is MagSafe charging on the iPhone 16?
Apple lists up to 25W with a 30W adapter. Its support page notes the iPhone 16 and 16 Pro peak at 22.5W, while the 16 Plus and 16 Pro Max reach 25W.
Do Lightning chargers work with the iPhone 16?
Not the cable. The iPhone 16 has a USB-C port. Lightning cables won't fit. Your USB-C power adapters still work with a USB-C to USB-C cable, and an old USB-A cube will charge it, just slowly.
