Can the power supply charge iPad Pros?

[Chairman.Jobbie]

Can the 87W power supply for my new 2018 15" MacBoo Pro safely charge my 2017 iPad Pro 10.5"?

Also, can the 61w power block charge the MacBook Pro? I probably not and probably wouldn't do it.

But if the 87W can I might sell the 61W and buy another 87W so I can keep one in each location.

Yes, usb c to lightning cable can be used to charge ipads/iphones etc from macbook charger.

And yes, the 61w charger will charge 15" too, but slower, and battery is more likely to discharge under heavy usage.

Yes and Yes.
I use 45W Anker USB-C power supply to charge my 15inch MBP when on travel and it works just fine. It charges slower and when I use MBP heavily, it will not really be increasing charge, but in typical use it charges just fine. My MBP idle power consumption is less than 20W with internal display and about 25W-30W with 4k + internal displays. Most of the time our computers are at idle anyway... So 45W will charge slowly even in external display setup. If not running performance applications, you should be perfectly fine. Now, if you throw at it some serious and long job, you may find out that there are limits ;-) But that's why batteries are there.

In general, as long as the power supply output voltage matches the input voltage for the device, any charger can be used to charge any device. Devices won't draw more current (and power) than they need, so even if a supply can output up to 87 watts, the device will only pull what it needs. As noted above, if the device wants to pull more power than the supply can provide, it will 1.) charge slower and 2.) may actually discharge if your trying to use it while charging.

I realise now the charger I have is a 29W charger that I was using to fast charge my iPad, and not 61w I said. Can this 29W apple charger safely charge my new MacBook Pro 15? I realise if it can it will be slow but thats fine. I just want to double check that its not causing any harm - itll just mean I dont need to take my 87W charger around with me or buy another one.

Sure, but if you’re actually doing anything that exceeds the 29w it’s putting in, the battery will start draining.

Will the 87w charger with a usb-c to lightning cable charge my iPad Pro at the faster rate? I was reading a review on the Apple website that the 29W/30W is better because of something to do with the volts?

"It will charge the 12.9" iPad Pro, but not at 29W. The output specifications suggest that it will charge at 12W instead (5V/2.4A) since it doesn't support a 14.5V/2A output."

Im thinking of selling my 29W and getting another 87W then it can charge all my devices with the appropriate cable. Should I keep the 29W?
