Hey guys, I’ve been using the factory 18 watt charge for the iPad Pro 11” with pretty good results. But, they do take a while to charge. I decided to try the Nintendo Switch usb-c on my iPad Pro 1TB model..

It flies! I went from 15% to 59% in probably around 10 minutes.

I could feel some serious warmth coming off my iPad, and after confirming the 39 watts and very impressive charging results, this all made sense to me.

Anyways, just figured I’d share! The Switch charger is over twice as powerful and longer too! So, if you have a Switch your in luck as it works like a charm!

There is some concern that rapid charging will wear a battery down quicker. I don't know if that is true (I've been using the retina Macbook AC adapter to charge my 1st gen 12.9 Pro and haven't noticed anything) but it is something worth researching... especially since you have the 1TB model (excellent decision IMO)

Your probably right, I’ve only used it one time. I plugged it in thinking, let me try this out. Then I checked on it literally 10 minutes later in disbelief to how charged my battery was “holy crap”!! Lol. The Nintendo Switch charger does great, it seems to work crazy fast charging up to around 65%. Then the charge slows to average speeds after 65-68%. I was keeping an eye on it pretty carefully

I’ll only use it every now and then, usually the battery last all day.

Anyways, I know apple sells higher wattage chargers for the iPad Pro. Or I could even use a MacBook pro charger. But, they are kind of expensive.

Good tip. But I won’t try it. As a R/C hobbier myself, I know the dangers of pushing too much current into a lithium filled cell. They can swell up or worse. There’s just no need to run a risk of harming a delicate lithium cell inside an iPad Pro.
Just watch

Lol. The iPad Pro includes the standard 18 watt charger, but apple sells faster chargers that are compatible with the iPad Pro, they sell a 31 watt charger I think. And much more higher wattage chargers too, but the iPad will only draw a maximum of around 30watts no matter how high the charger is rated.

But yes, I’ve done some crazy stuff with lipo batteries and RC cars! Plenty of 8S diff exploding fun haha.

You can fix your own lipos if they swell, I’ve always released the gas inside being very careful. And I get double the life. Lithium is not stable around moisture, so if it is exposed the humidity in the air will easily ignite it.

If you ever worry about a lipo exploding keep a small Tupperware container on hand filled with denatured alcohol and drop the battery in.

Ever since the first iPad Pro people used 30+ W chargers on these without issues. It might wear the battery a bit more, but I doubt you’d realize that over the lifespan of the device.

Hello !
I was using my MacBook Pro charger for my iPad Pro since I bought it (2 months). This thread put me in doubt, so I contacted the Apple assistance.

Here is my question and their answer translated (1st photo attached):

" - Hello, no issues with my iPad Pro 2018, which I really likes. However, I was asking myself a question : Can I use my MacBook Pro charger to charge my iPad Pro 2018 for fast charge ? Does this more powerful charge can damage the battery on a long term ?

- No, it's not recommended to do it, only in case of an absolute needs. It can harm the iPad."


The weird thing is that this woman told me to not do it but on the Apple support page you have this message (2nd photo attached).

Anyway, I'll avoid to use my MacBook Pro charger in the future.

The iPad will only ask the charger for the current it was designed to charge at. It is ok to use a more powerful charger. I’ve plugged the 87 watt usb c charger into my iPhone and iPad 2018. They don’t charge much faster than the 30 watt usb c charger.

Batteries today handle rapid charging much better than batteries in the past. Heat is a huge detriment to any battery.

You have the answer in writing. I wouldn’t take the word of a chat support agent for it. People tend to make mistakes and give out wrong information. Every second post advice on batteries on this forum is plain wrong, which reflects the dubious state of knowledge about rechargeable batteries in the overall population.

There is a lot of poor information in this thread.

Current isn’t pushed. It’s pulled by a load. You could attach a nuclear power station to your iPad and as long as the voltage is correct it would happily charge just fine. Your MacBook charger isn’t a charger. It’s a power supply. The charger is built into the iPad just like it is your MacBook. The RC reference above isn’t relevant in this case because unlike your RC gear, you don’t control the charger in the iPad. Unless the charger built into the iPad is defective there is no way that simply providing a power supply capable of higher current delivery can damage your iPad or it’s battery.

Thanks for the tip, I have a 2018 iPad Pro 12.9 and Switch, and it never occurred to me that the Switch's power supply could be used with my iPad.

I have used the Nintendo Switch power supply probably 5 times now. It is easy to unplug from the switch dock, lay my iPad down right beside my tv and it charges. And I’ll plug the cable right back in to the switch when I’m done.

Your right. I never was worried about the charger causing any harm.
 
I have the 30w charger from Apple - I use. it everyday on my 2018 12.9". I charge it then unplug when full.
