iPad Pro Does 11" iPad Pro charge well with a 12W charger?

[sananda]

I'm thinking about getting an 11" iPad Pro because my 2013 iPad Air is getting very full (also for some reason having been stuck inside for 46 days I think I want a present).

I read on a website - https://www.inviolabs.com/blogs/news/new-ipad-pro2018-usb-c-fast-charging-test - that the 2018 iPad Pro "does not support the APPLE2.4A protocol" and therefore when used with the Apple 12W charger "has a poor charge of 5.14V / 1.41A / 7.26W".

I'm currently charging my iPad Air with the 12W port of the Anker PowerPort Speed PD 5 and was planning to continue using the port with the replacement iPad Pro (the PD port having other duties). Am I going to be charging at 7W?

I have the same charger and the iPad Pro 12.9 (3rd gen). I can confirm this, while I don’t know the exact charging rate, it’s definitely sub 12W. It takes me around 5-7h to fully charge, however, I actually appreciate it as I can charge it overnight and avoid battery degradation which would come from fast-chargers.

Yeah, I only ever use fast chargers when they're necessary.

I hadn't considered battery degradation. So perhaps there is an advantage to it charging slowly.

Over the 3-5 years of device lifetime I doubt anybody will see a difference in battery life or performance.

I don't think so. I've used fast charger on tablets and phones for a long time and haven't seen other-than-normal degradation.

I am a bit confused to be honest. Why do you want to use the 12W Anker charger with the iPad Pro 11 when the iPad itself comes with 18W charger? Why don't you use the original charger that comes with the box?

I see the point in using the 12W charger with the iPad Air as I assume the Air's charger in the box is 10W. I just don't understand why you want to use lesser charger than the one in the box for the iPad Pro.

The short answer is: lack of sockets.

Because it's not that I want to charge one iPad Pro 11" with a 12W charger rather than charging one iPad Pro 11" with an 18W charger.

It's that I'm trying to work out whether it's a good idea to continue with my current set up. At present I can charge my MOVI Cinema Robot, iPhone, iPad, Apple Watch and camera with one charger at the same time. And none of the Apple devices is charging slower than using the original charger (the iPad came with a 12W charger).

I realised I needed a set up like this when I went to Japan for a month and took individual chargers. When I got to the tiny apartment I had rented, I found that there weren't enough sockets. There are never enough sockets in hotels either. I ended up unplugging the washing machine to use the socket to charge my camera. A pipe above the washing machine leaked and water got inside my camera. As it's a Japanese camera, I was able to get the LCD replaced at the service centre. But it took three weeks so I couldn't use it on my holiday. I decided I wanted to be able to use one charger for as many devices as possible in the future.

I enjoy using one charger for all my devices at home too. It's neater and means I don't have to use multi plug extension lead.

I just wanted to find out if it it's true that iPad Pro 11" doesn't use all the 12W from a 12W charger. And now that @totom_ has confirmed it's true, I don't know if I'll charge it with one of the Anker charger's 12W ports, or whether I'll charge it with the Power Delivery port and charge the MOVI with the 12W port instead .

I'll have to think about it further and consider battery degradation while deciding.

Charging the MOVI from a 12W port will not be particularly fast - their website says it only draws 2.5W and takes about 8 hours.

However, you’re presumably not using it right up until you fall into bed. Plug it into the PD port until you need to charge the iPad, switch it over and leave the iPad plugged into the Pd port. Job done.

Kind of.

What Anker charger do you have? When I was looking to buy chargers last time around (not sure if this applied to Anker or not, but they were one of the brands I looked at and didn’t buy) mixing usb-A ports and usb-c ports led to a disappointing compromise. For instance, I have one charger now that can do 30W from the USBC port and 30W from the USBA port but if you plug a cable into both it defaults to somewhere around 5W charging. It’s an either/or thing, really, with some.

Look at the total wattage. For example:

If you have a device that pulls 18W connected to USB-C, you've got 42W left so ~10W per USB-A port. If your USB-C device pulls 30W though, you only have 30W so up to 7.5W per port if you use all 4 with high consumption devices.

This one can give you the full 30W USB-C and 12W USB-A but it only has those two ports.

Is using two sockets not an option at all? Could use the iPad 18W charger for the iPad and the multiport for all other devices. That said, if charging overnight anyway, does not having fast charge matter? It'll probably still be 100% when you wake up.

Looking at the wattage isn't enough because it will step down below what it is theoretically capable of. Xiaomi have a 30W charger which steps down to max 12W at each port if you use them both (1C1A).

The Anker charger you linked to is only capable of putting out 30W from the 4A ports, no matter what you have connected to the 1C port.

Thanks for the correction. I'd forgotten about that.

That said, most dual port chargers are simple to deduce based on total wattage and max output from USB-C. I have a 30W Anker but that's 18W max USB-C and 12W max USB-A.

That's a good option.

What Anker charger do you have?

Ive got the PowerPort Speed PD 5.

Here are the specifications:

It's possible just not convenient.

But as you say, if it charges overnight that's probably all that really matters.

I didn't get an iPad Pro, I got a fourth generation iPad Air. It charges at a max of 5W from the 12W port of my Anker PowerPort Speed PD 5 and takes 7 hours and 17 minutes to go from zero to 100%. Using the PD port, it maxes out at 28W and takes 2 hours and 13 mins to go from zero to 100%.
