iPad Pro Slow charging iPad while connected to USB-C to Digital A/V adapter.

[Populus]

Hello there.

I finally bought the Digital A/V adapter, the one with HDMI, USB-A 3.0 and the power USB-C For my 11” iPad Pro. And I’m experiencing a slow charge, maybe 1% each 4-5 minutes? I’m not sure this is the normal speed when charging it just with the USB-C power cable, but I think it is slower with the adapter attached and an HDMI monitor plugged in.

So... Is this the normal charging speed? Or does the dongle actually limits the speed it charges? The only app I have open at the moment is Safari, and even if I close it, the charging speed is slow.

Thank you.

PS: Yesterday while playing Fortnite and the HDMI external screen plugged in, it didn’t even charge at all. It remained at the same % or even dropped. I thought that was normal, but not with every app closed.

Ok, I just measured the time it takes to gain 1% in battery percentage, and it takes 4 minutes with the HDMI screen attached to the dongle, and the power connected to the USB-C on the dongle. And 2 minutes (half the time) connecting the power USB-C adaptor directly to the iPad with no dongle.

Now I am watching if it charges at the same speed with the USB-C dongle BUT without the HDMI screen attached.

EDIT: Ok, it is the dongle itself. Without any other device plugged in, just using the dongle itself, it charges at half the speed.

Connected to power directly: 2 minutes each 1%.
Connected to power throughout digital A/V adapter: 4 minutes each 1%

Is this normal? Is the Digital A/V adapter designed to use half the power?

Thank you.

I think it’s normal but perhaps someone else can chime in and correct me. Once the port on the iPad determines that it is being used for external device activity the power delivery into the device isn’t going to be at the same current because the port is now operating in a data mode rather than a power delivery one.

What is happening, imo, and you see this with other brand of adaptors, the adaptor itself draws X number of watts.

Per Apple:

Because this adapter draws power from your Mac or iPad Pro even when your Mac or iPad Pro is asleep, you might want to unplug it when it's not also connected to power for charging.

About the Apple USB-C Digital AV Multiport Adapter - Apple Support

Connect a Mac that has a Thunderbolt 4, Thunderbolt 3, or USB-C port to an HDMI display, while also charging your Mac and connecting to a USB-A device. iPad models that have a Thunderbolt or USB-C port can also use this adapter.

Another example, I have an Anker hub, and that draws about 15w for itself and anything plugged into it. Anything left over goes to the computing device, so, my MacBook will be in basically a trickle charge mode. And depending on how much work the device is doing, might not be enough power to keep up.

I see... thank you guys!

Hopefully I will have no problems using it with a future MacBook Pro, with a much beefier power supply.

I bought the original Apple Digital AV adapter because I will probably need it in the future with more devices, as USB-C is a standard now, and the present/future is USB-C. And some of the original adapters I have are 12 years old, so its quality and durability is out of doubt.

I'd think otherwise.

I’ve tried using usb-a to usb-c cables to charge my 2020 iPad Pro from various power supplies and power banks and only get a 1amp charging rate, it’s quite frustrating.
