If you’re wondering which charger to use for the iPhone 17 and want your iPhone 17 to charge quickly, Apple gives a very simple tip: to get "up to 50% in 20 minutes" you need a power adapter with 40W or more. This means a 20W charger will work, but it’s not the "target" for fast charging, and 45W is a reasonable starting point. Then there’s everyday convenience: it’s good to have a charger that can power up your iPhone and one more device, instead of carrying around several charging bricks.
How to choose a charger for iPhone 17?
There are 4 key things: power, USB‑C/PD, ports, and cable.
Power (W)
If you want to charge “just like Apple promises,” aim for 40W or more. The simplest way is 45W. If you want some margin for the future and the possibility to charge several devices, it makes more sense to go higher and get 67W.
USB‑C and charging standard (PD)
iPhone 17 charges via USB‑C, so choose chargers with a USB‑C port. Ideally, they should support USB Power Delivery, as this is the most compatible charging standard for new phones, tablets, and some laptops.
Ports
One USB‑C port is enough for just your iPhone. But if you’re charging AirPods, a power bank, or a second phone too, an extra port is simply more convenient.
Cable
In practice, it’s most convenient to have a good USB‑C → USB‑C cable (one at home, another in your bag). Length matters too: a longer cable is much better for the desk or bedside.
Recommended – good charger for iPhone 17 (one list)
Anker Nano 45W USB‑C Charger (includes 1.8 m cable)
For whom: you want a small, pocket-sized charger that meets the 40W+ requirement and immediately provides a cable for convenient charging.
Pros: 45W, compact design, USB‑C → USB‑C 1.8 m cable included, great for home and travel.
Cons/notes: this is mainly a charger “for a single device”, so it's not as convenient for charging several devices at once.

Apple 20W USB‑C Power Adapter (2025)
For whom: you want a simple, official Apple charger, but you accept that this isn’t the option for “the fastest possible top-ups” above the 40W+ range.
Pros: simple, lightweight, works with practically any USB‑C device.
Cons/notes: cable sold separately, and 20W is more of a “basic” standard than fast.

DEKO TRAVELER 67W GaN Fast Charger (2× USB‑C, 1× USB‑A) + USB‑C cable 100W 1 m included
For whom: you want a single charger for your iPhone 17, but also for a second device, and additionally you care about having extra power for the future.
Cons/notes: if you charge several devices at the same time, the charger splits the power between the ports (this is normal).
Which one to choose most often?
If you want to meet Apple’s “40W+” requirement and have peace of mind, the Anker 45W is the simplest option.
If you want a single charger to last for years, both for your iPhone and additional devices, the DEKO TRAVELER 67W is more versatile and more convenient thanks to its extra ports.
Apple 20W only makes sense if you intentionally choose slower charging and want the simplest possible official power adapter.
FAQ
Does the iPhone 17 really need 40W+?
Apple states that to achieve “up to 50% in 20 minutes,” you’ll need a 40W or higher power adapter, so if you want that kind of charging speed, it’s worth going for 45W or even 67W.
Isn't 67W too powerful for the iPhone?
No. The iPhone will only draw as much power as it needs. 67W just means extra headroom and more versatility.
Is a 45W charger sufficient?
Yes, because it exceeds the 40W+ threshold suggested by Apple for fast charging.
Will the iPhone 17 charge faster with a 67W charger than with a 45W one?
Not always. What matters is how much power the iPhone 17 actually draws at the moment (the phone limits its own power intake), so 67W mainly provides extra capacity for other devices and greater flexibility, rather than a “magical” speed boost beyond the iPhone’s own capabilities.
Can I charge the iPhone 17 using USB‑A (old cable), and does it make sense?
You can, but it will usually be slower and less predictable than using USB‑C. If you care about fast charging, choose USB‑C → USB‑C and a USB‑C charger.
Will charging in a car (USB‑C) be as fast as with a wall charger?
It depends on the car charger: if it has USB‑C, sufficient power, and supports fast charging, it can work very well, but cheap adapters often have poor specifications and actually charge more slowly than a good quality wall charger.
