Some USB-C Power Banks Fail to Work With iPhone 15

TexanGalaxy said:
Not sure if apple has the feature yet but having a setting to receive charge or give would help. As the phone doesn't know what its attached to. Wireless should already have a option.

Not creating a war, but i had the problem on my galaxy s23 ultra.

I don’t think it’d help in the case where one is connecting to an “input” port, though. And, in that case, all it would do is confuse the person as they’d be thinking that they set the phone to take a charge, why isn’t it working!?

Just to add another data point.. I have an A1245 Anker 10000 slim PD and mine doesn't charge my iphone 15 pro via USB-C, but can charge my other iphones that use lightning.

I also retested my setup and it did not work. I have the same battery pack and it worked on my iPad but not the phone. Hopefully this will be fixed via software.

This is not Apple’s problem and they have no need to test anything. Apple have made the iPhones totally compliant with the PD spec.

Anker has configured some of their cheaper power banks assuming that most phone makers won’t implement the bi-directional aspects of the spec - which most Android phones don’t.

Anker knows how to implement this properly, which they do on their more expensive power banks, including the one I own which is pictured below - with clearly labeled input/output ports.

Is this just your opinion or do you have some sort of technical documentation that proves it? How would YOU know?

Ah, I was just googling this and there are specific Anker chargers that include “two way charging” in their features. I’d expect the problem ones don’t say this.

Hmm...too bad that in my own personal use cases...those newly enabled features and functionality are pointless gimmicks that I'll never use. I haven't seen a single one of these new features or functions that look useful. But I DO have to go purchase a new cable though so I can continue to be able to use CarPlay. So this switch doesn't offer me anything beneficial but it does require a purchase that wouldn't have been necessary if the switch wasn't forced. Oh and all the docks in my house, and the one I have at work...are now useless. Some of which weren't cheap. I don't think switching was the right move (by mandate, specifically. The EU can go pound sand for all I care instead of sticking their noses where they don't belong) and I don't see that changing. The one on my iPad doesn't always work (which is a problem I NEVER had with Lightning) and one of the ones on my Mac doesn't either.

This is what we call missing the forest for the trees.

You think a common charger for all personal electronics is a pointless gimmick? sorry you invested so heavily in a power connector that apple told us would last 10 years. as they said when it was introduced it lasted 10 years. so why are you so surprised? did you think it would last forever? The lightning cable was proprietary and so while it was great for your phone USB-C is going to be a universal power adaptor for any personal electronics device you can think of. the ecosystem of accessories you can potentially use just got bigger. The "gimmicky" features like charging your AirPods or watch from your phone are minor perks. The iPhone and macs now share a common connector.

you're so bummed about having to buy some new cables and lose your old dock that you're missing the bigger picture. honestly the thing most of us learned from the iPod era was don't buy a dock, especially and expensive audio dock. because it will be junk in 3-5 years. The bigger picture is that your old dock was never going to be compatible with apple's new charging port regardless of if it was type-C or hypothetical lightning 2. The EU is looking at a much larger scale, I would not be surprised if laptops stopped coming with chargers now because people will already have them. the same charger you use for your mac can charge your phone, electric shaver, digital camera, headphones, smart watch, bike lights, etc... its all one unified power standard. every electronic device you use is going to have USB-C.

With regards to your iPad not always working... yep, there will be some growing pains. A lot of cheap chargers might use cheap PD controllers that don't follow the spec. I remember when people got electrocuted by using off brand lightning cables/chargers. another thing to remember is that just because the port is standard doesn't mean that every device can provide enough power to use an accessory. for example Ive seen videos of people trying to use USB-C audio interfaces with their iPhone, and the interface doesn't power up. this is likely because during the power negotiation between the phone and interface the phone listed its source capabilities and none of them were compatible with the interfaces sink requirements. you'll have to know the source capabilities of your phone, just like you knew that even if you had a 60 watt charger connected to your lighting to USB-C cable, the iPhone can't charge at 60W.

anyway, this is the 3rd time I've been through a connector change, its really not a big deal. I am not going to miss lightning.

ok, bit late to the party, just found out my anker 10.000, model A1245 doesn't charge iPhone 15 pro and pro max. Tried a different cable, didn't work either (usb-c to usb-c). It charges the iPad Air 4th no problem. So I guess there is some mis alignment there. I grabbed an usb-a to usb-c cable for now, bit surprising this whole thing.

Happened to be at the Apple Store London, the person helping was surprised as well, guess it's not that known yet.

It “happens” with Belkin BPB001. When the power bank runs out of battery, the iPhone starts charging the powerbank.
 
I have the A1245 and it will only charge my iphone 15 pro if I reboot the phone after i connect the power bank, but then it works upon reboot. Since I typically only use this bank for my Quest 3, it's not the end of the world the 1-2 times every few months I use the bank while traveling, but it is reliable that this works. I have two A1245's and had the same situation with 4 different iPhone 15 Pro's in all combinations. (this is only using USB-C port, have no idea if the A port works fine)

Kicking this dead horse again. The battery pack now works! Someone else mentioned that as of 17.2 the pack will now charge the phone. I tried it last night and it worked great!

We understand the importance of having a reliable power bank for your vacation. The reverse charging issue with the iPhone 15 Pro Max and power banks using USB-C charging has been reported. However, there are workarounds that you can try. Firstly, you can use the USB A port instead of the USB-C port for charging. Additionally, powering off your iPhone 15 before using the power bank to charge might resolve the issue. Before making your purchase, it's advisable to test these workarounds to ensure compatibility with your iPhone 15 Pro Max. This will help you avoid any inconvenience during your vacation. If you need further assistance or have any other questions about your Anker product, do not hesitate to ask. I'm here to help!

This is the reply I just got from Anker. They were really quick to respond btw.
But I’m not gonna use USB-A to charge…
 
when the iPhone came out it didn’t matter which device had more power. The phone would always charge the battery pack. Now it’s a one way relationship.
 
Anyone have the Anker Nano Power Bank (30W, Built-In USB-C Cable) (A1259) and can confirm if they’re able to charge their iPhone 15 Pro/Pro Max via USB-C? Mine keeps kicking into reverse charging! The Powerbank is damn useless to me.
 
I don't have the Nano, but I did end up buying the Anker Prime 12.000mAh and I've used it throughout my vacation without any reverse charging issues.

I didn't try it any other way, but I always pressed the button for it to wake up. Then add a USB-C cable to the powerbank first. And then plug the cable into the phone.

I don't know if any of that matters.
But I didn't have any problems with reverse charging
