I am just about to walk into the Apple Store.

I have both 29W and 85W USB-C chargers (that came with my MacBooks).

If I buy the USB-c to lightning cable, can I use either of these to charge my 10.5" iPad Pro? And is the officially confirmed by Apple?

Apologies if this has been answered before, but I am really confused with what is okay and what is not with the 'fast charging' stuff.

As i understand it, the 29 watt charger is the best for ipad pro as it supplies the relevant voltages.

They 85 will work, but maybe not as well as the 29.

Apple do suggest that the Macbook charger will work for fast charging (i did look it up the other day).

I can confirm the 29 watt works. I bought one today.

Thanks, mate. I just picked up the 2M cable for £35. WOW!

Yeah, i got the 29 watt charger + 2M USB-C to lightning cable. $118 australian.

So yeah. I've spent like $1700 on the ipad this month already. The device, the charger, pencil, keyboard cover, a few apps....

still. worth it. happy so far. they really should include a bigger charger tho. goes for most apple devices though, same with the MS surface too. supplied chargers are all borderline.

It's my understanding that there are chips embedded in USB C cables - the dongle will disable the quicker charge in order to make sure it doesn't override the limits of the regular USB cord.
That is helpful, thanks. Guess the answer is no then. I had a spare dongle, so just thought it may be with a shot!

It will still be worth a shot. Just rumour i have heard that the 29 might be faster.

The larger chargers won't break anything, but you'll want to do a time comparison to see if it is an improvement vs. either the 29 watt charger or the 12 watt charger. There's no point carrying around a larger 85 watt charger if it charges the same speed as your 12 watt, or same speed as the 29 watt...

But yes, rumour has it that the 85 watt charges slower than the 29 because it doesn't supply the fast charge voltage relevant to the 10.5 fast charging. Just something i read on the internet tho.
