The best GaN fast chargers for iPhone in 2026
1. Anker Nano 30W GaN — best overall
The Anker Nano is the default pick for most iPhone owners. It is 30W of GaN (gallium nitride) charging — faster than standard 20W USB-C — in a tiny, foldable adapter that fits in a pocket or a small bag. It works with the iPhone 17 Pro, iPhone 16 Pro, and any iPhone 12 or later, and it charges an iPad or USB-C power bank too — see our iPad accessories guide for what to pair with a tablet. It is a well-reviewed, widely bought option, and it is frequently one of the most compact 30W fast chargers you can get — an easy buy for anyone who wants faster charging without paying for brand name alone.
2. Apple 35W Dual USB-C — best for households
Apple's 35W Dual USB-C Compact Power Adapter is the right choice if you want to charge two devices simultaneously — an iPhone and an iPad, or two iPhones, or an iPhone and AirPods — from one adapter. It is a compact first-party dual-port option: one small wall adapter with two USB-C ports. It is made by Apple, which means it is designed to work perfectly with Apple devices and you get Apple's support and warranty. For most households where the phone and a tablet or second phone are always charging, this is the cleanest solution.
3. Belkin BoostCharge 30W — the middle option
Belkin is the third credible option in this space. The BoostCharge 30W GaN charger is a well-made, reliable 30W fast charger from a brand that has made USB-C chargers for Apple's ecosystem for years. It is a good choice if you want the same performance as the Anker Nano with a brand that has a slightly more premium feel. If its price lands better when you look, it is a legitimate buy for the same core outcome as the Anker.
What GaN actually means for your phone
GaN (gallium nitride) is a semiconductor material that allows power adapters to be significantly smaller and more efficient than the old silicon-based chargers. The practical result: the Anker Nano and Belkin BoostCharge are pocket-sized 30W chargers — far smaller than the 30W or 35W adapters that would have been made with the older technology. There is no meaningful difference in charging speed between GaN and silicon chargers at the same wattage — the benefit is size and efficiency, not raw speed.
How fast should your iPhone charger be?
- 20W USB-C — the baseline fast-charging speed for iPhone. Fine for most people, but slower than the 30W/35W options here.
- 30W USB-C — the Anker Nano and Belkin BoostCharge speed. Meaningfully faster for the 17 Pro, 16 Pro, and most iPhones, and fast enough for iPad fast charging.
- 35W USB-C — Apple's 35W dual adapter. Same speed for a single iPhone as the 30W, but it can charge two devices at once.
- 18 Pro-ready note: All of these chargers will work with the iPhone 18 Pro launching Sept 9 — USB-C fast charging is fully compatible. No need to wait for a new charger when the 18 Pro arrives. For everything confirmed so far, see our Sept 9 event roundup.
Bottom line
For most iPhone owners, the Anker Nano 30W is the best buy: compact, affordable, and fast enough for any current iPhone. If you want to charge two Apple devices at once, the Apple 35W Dual USB-C is the cleaner option. Belkin is the middle ground if you want a slightly more premium brand. All three are fully compatible with the current iPhone lineup and will work with the iPhone 18 Pro when it launches. For more on wireless charging options, see our MagSafe power bank roundup.

What is the difference between GaN and a standard silicon charger? GaN makes the charger smaller and more efficient. The charging speed at the same wattage is the same; the benefit is physical size and battery efficiency.
Will these chargers work with the iPhone 18 Pro? Yes — all three chargers listed here are fully USB-C compatible and will charge the iPhone 18 Pro at standard fast-charging speeds. No new charger is needed when the 18 Pro launches.
Should I buy an Apple charger or a third-party charger? If you want the cleanest Apple ecosystem experience and need dual-device charging, buy the Apple 35W. If you want the best value and smallest size, the Anker Nano 30W is the right choice.
