Hey there! Does anyone know what the minimum wattage requirement is to charge the M1 iPad pros? I have two external batteries. One puts out 5W and the other 10W but neither of them will charge my M1 iPP 11. Thanks!

I think the minimum is 18W, They come with a 20W wall charger. I use a Anker 18W wall charger as well. If you search on Amazon for a battery charger iPad Pro they are 18W and up…

Thank you! I like Anker products and also have a couple of their wall chargers. I guess the batteries I have will be used for my iPhone and AirPods Pro. It is time to go shopping at Amazon for a new battery.;)

that's strange, the 2018 one comes with the same charger but can be charged with anything, including 5w power banks (of course very slowly). Generally, when a laptop cannot charge with a low power device it's not a matter of minimum wattage, but of charging protocol (topically it requires Power Delivery 2.0 or even 3.0 to charge, and cannot fall back on the standard 5v charging, regardless of how many watts those 5v can pump (generally between 5 and 15)).

I've charged my 2018 11" Pro with a 5/10W and USB to USB-C cable many times in a pinch. I usually use a 15W (5V-3A) USB-C charger for a balance of speed and longevity.

It is strange your 5/10W portables are not working, although I wonder if the 2018 has different requirements than the 2021? I would thing Digitalguy is right... that any 5V charger should work no matter the current.

Ok. I actually have 3 batteries all with similar specs and none of them trigger the charging mechanism on my iPad Pro. The iPP does work with all the wall chargers I have for it, lowest being 18W. I dunno. I do see a lot of battery packs that specifically advertise work with iPP 2021 that are 18W and above. Not that big of a deal. Amazon has a ton of them and they're not that expensive. Anker makes some good products. I'll probably just get one of theirs.

Edit: Just to add to the mix. My older Apple 10W iPad charger does not trigger charging on my M1 Ipad Pro either.?

That probably means that the iPad pro with M1 needs Power Delivery contrary to previous models. Generally PD starts at 18w, which is achieved with higher than 5v (5v can only go to 12w with USB A and 15w with USB C), typically 9v or 12v, while a 10w charger only charge at the 5v voltage.

My iPP 11/M1 can be charged using 12w adapter (iPad Air 3 charger), though the speed is very slow.

I use an Anker Powercore 13000 battery to charge my M1 iPad Pro 11”
Yeah, I have plenty of chargers. It's a portable battery to throw in my bag when out and about that I need. Anker has several of those also. Just need to head to Amazon and pick one or two up.;)

The KEYMOX is in my bag. The Anker 40W is on my charging stand. The Anker 27W is on my charging stand. The Apple 20W is my nightstand charger.

According to this article, "You can use any of the adapters listed below to charge your iPhone, iPad, Apple Watch, or iPod" - so theoretically, 5W should "Work" but I don't even have a 5W charger around to test any more.

Well, I don't know what to say about that. I have 5W and 10W chargers, and none of them trigger charging on my M1 iPP 11, but the 18W and up do with no problem.

Just a thought, you're obviously using a USB-C to USB-C cable with 18W and a USB-A to USB-C cable for 5W and 10W. Maybe it's not the chargers but rather the cable that's problematic. Have you tried using a different USB-A to USB-C cable?

Yes I have, to no avail. All my cables are from Anker except for the Apple cables. I could understand if I was using older cables not compatible with new tech, but the new cables are advertised as backward compatible and should work just fine with older chargers and batteries. Two of the batteries in the picture above are only a year old, so there should be no compatibility issues there either, other than the fact that they are much lower wattage than the charger that came with my iPP. I have several chargers that work just fine. I just need to get a couple batteries that are advertised to work with the M1 iPP.

Does anyone here actually have have an M1 iPP that works with chargers and external batteries that put out 10W or less?

Tested just now and my M1 iPad Pro 11 charges fine with both a multi-port charger and the 5W charger shipped with the iPhone SE 2020. The multi-port can output up to 15W on USB-A but the iPad only pulled ~5W.

P.S. 5W charging is darned slow. Only got around 10% charge after 1 hour plugged in.

Well damn! I am going to have to do some more experimenting and report back. The same cables that work with 18W and up chargers just won't work with the lower wattage external batteries I have and I don't know why. And why does my older iPad 10W charger not work with my iPad? Using the same cord that I do with the Anker Elite 24W charger.

Well evidently most of my USB A to USB C cords aren't compatible with my M1 iPP. All the batteries and the iPad 10W charger work with this cord.
ohgeez.gif
Guess I don't need new batteries. I need new USB A 3.0 to USB C cords.
haha.gif
None of my USB A to C cords are more than a year old. Seems like they should be current technology. Especially since they are made to plug in to USB C devices.

That's OK, I just tried my 5W and 10W and Anker 13000 battery bank, They all worked with my Anker USB-C to USB-A. The good news is you can even get a cheaper lighter battery bank now.

Thanks! I guess I could always use another battery. The 3 that I currently have in these pictures do in fact work with this Anker cable, but none of my other USB A to USB C cables work, so it is definitely cables I need. I am over at Amazon searching as we speak. Not sure I want the Anker again at $19.00 each. I might get another one of those, but search for a pack of less expensive one's just for extras.

Edit: Looks like these should work just fine.

This is the cable I used for my charging tests.
