PSA: iPhone 8 Fast Charging Works With Third-Party USB-C Power Adapters That Support Power Delivery

A recent support document on Apple's website confirms that you don't need one of Apple's USB-C power adapters to fast charge the latest iPhones.

Apple says the iPhone 8 and iPhone 8 Plus, and presumably the iPhone X, can be fast charged with any comparable third-party USB-C power adapter that supports the USB Power Delivery specification.

An official Lightning to USB-C cable is still needed, and it's not included with any iPhone. Apple charges $25 for a one meter cable, and $35 for a two meter cable, in the United States. There aren't any MFi-certified alternatives yet.

Apple's own USB-C power adapters that support USB-C Power Delivery include:

Aukey has a few cheaper third-party options available on Amazon:

29W USB-C Power Adapter — $22.99
46W USB-C Power Adapter — $39.99

Fast charging enables the iPhone 8, iPhone 8 Plus, and iPhone X to charge to 50 percent battery life in just 30 minutes.

This doesn't explain a question a lot of people have though: Will the 61 or 87W charge *faster* than the 29W? Is the highest power output the iPhone support 14.5V@2A or 9V@3A? The 29W Charger is the only one that has the specific 29W profile.

I was definitely confusing Aukey and Anker.

Also, I live in Canada, and was redirected to Amazon.ca, which didn't mention the Lightning incompatibility.

I've updated the article to address all of these issues.

Thanks!

I didn't know an editor lived here, cool!

This is indeed great news. HOWEVER, Anker specifically states that USB-C to Lightening cables are NOT supported. I confirmed that with Anker last week via email.

Can anyone explain why it must be a USB C cable to Lightning and not the regular USB A? There are plenty of USB A Power Adapters that can draw 29W or more.

Fast charge capable iOS devices are able to do so via USB-PD. Only USB-C output supports USB-PD, hence the required Apple USB-C to Lightning cable.

Nobody has done tests yet with all the chargers? I don’t know if I want to take The iPad forums word on it without any iPhone testing.
I have a few 87w adapters sitting around

Personally based on my limited testing which shows that the iPhone 8+ charges at 9V at 70% charge level, I think it's just going to charge at 18W maximum. It's unlikely to charge faster than an iPad Pro (29W) and given the small size of the battery, 18W or 9V/2A sounds more reasonable.

That's nice. I'm still not paying $25-$35 for the stupid cable.
