No it does not charge at all with Samsung charger. I'm keeping fingers crossed mine wasn't a faulty unit hence this thread.

I reckon you might be on to something here re. handshake. The iPad when paired with Samsung 25W keeps connecting and disconnecting repeatedly (I can hear it from the sound cue), as if it had trouble identifying the charger. The battery icon turned green for a split second then back to white (discharge) status.

If the power adapter is indeed faulty how come it still fast charges my Galaxy very well? Or does it only apply to Apple as a third party device?

It's a nuisance to have multiple chargers when one will suffice. I do see the reasons why Apple removed the brick from their iPhone 12 lineup.

Might as well get a universal GaN charger off Amazon and put all of these little bricks back in box.
I had a similar problem with my 2018 iPad Pro: at first it would only work with some specific chargers but in time it was almost impossible to charge it at all, would constantly do the connect/disconnect dance or just either refuse to charge at all. I brought it in for repair at Apple but they gave it back to me with a letter stating that it was working perfectly. Turns out that all it was needed was a software reinstall: you might try that and see if it works for you.

Caveat if needing to charge laptops, the Choetech limits both ports to 45W when two devices are connected.

Meanwhile, the RAVPower 90W is a bit more flexible and can do 60W laptop + 30W USB-C iPad.
Thanks for pointing that out. I doubt any charger can power a gaming laptop with a 300W power brick :D

I have a Zendure Supertank Pro battery bank and it supports 100W via USB-C on a single port or 138W across ports. It supports the following 5V/3A, 9V/2A, 9V/3A, 12V/1.5A, 12V/3A, 15V/3A, 20V/3A, 20V/5A. I tried plugging my 12.9” M1 iPP in and it pulled 36W from the battery bank when the iPad was at 66% SOC. I’m not sure if it will pull more from a lower SOC but I’ll update if it does.

Wow, so the M1 iPad could definitely draw more than 30W! Would you mind testing whats the highest power draw could it be?

Same model, I got around 37~38 at 30% SOC. So I think it's limited under 40? I am using a 65W GAN charger.

I use my MacBook's 45w charger for my iPad Pro 11 (M1) and it charges crazy fast. I only have to have it on there for a few minutes when it's <80% and it'll fire up to 80% like a rocket. Absolutely love it. Say I'm busy reading something, I get up to take a 5-10 min walking break and come back to a charged iPad again.

I noticed if I plug my iPad Pro 11 into an Anker 20w charger, the charger makes some weird noises (doesn't happen with my iPhone). So I usually just charge with the MBP charger cuz I have to charge it so infrequently.

I am not a heavy user but I really like the rapid charging:

Charged to 100% yesterday cuz I accidentally left it on the charger (usually try to keep it 50-80%) - and it's still 95% this morning (8am Friday) - and I won't have to charge it again till Sunday/Monday easy.

Dang Apple News is taking up some serious screen off time....... despite background app data off.

I’m using a 96W Apple charger (from my 16-inch MacBook Pro) for my new 12.9-inch iPad Pro and it works great. So the power is not a issue I think. Apple explained this in a new support document. Here is the link: https://support.apple.com/en-us/HT209186#charge

I don’t think Apple is intentionally making Samsung charger not working. Maybe it’s related to a different tech of fast charging on Samsung’s side? I know they usually implement some more aggressive specs for fast charging.

Compared with the stock 20W charger which came with the device, how much faster does the 30W and 96W Apple chargers charge the M1 12.9" 2021 iPad Pro?

If buying an Apple charger, is it better to get the 30W or 96W USB-C Charger?

Max I’ve seen the M1 12.9 pull from the wall is 36-40W. I don’t remember exactly how much faster 30W+ is versus 20W but I know the difference is significant.

I have a 4-port RAVPower 65W with 45W/20W split when both USB-C ports are used. Charging from 50% to 100%, higher watt port finishes in about 1 hour while lower watt port is only 70-80% in the same amount of time.

It appears that this $80 multi-port charger above can accommodate these devices at these output.
  • 45W USB-C - iPad Pro
  • 30W USB-C - iPhone Pro Max
  • 10.5W USB-C - Watch or AirPods
  • 10.5W USB-A - AirPods or Watch
This same SKU charger can be had for $49 my home country.

And then use the original 140W charger for the MBP 16". I wanted a 5th port that can output 140W but I do not think any charger will ever do this within the next half decade at under $100
