2018 iPad Pro: can it be charged with an older iPad's power block?

[Jack Hennety]

Pretty much per the title.

In the UK the 18W USB-C power block that charges the new iPad Pros isn't available to buy (I wanted to keep one at work). I was wondering before trying out the theory, would an older iPad's 10W charger (A1357 to be precise) successfully charge the new iPad Pro, assuming of course I connect them with a USB-A to USB-C cable?

Would it cause any harm?

I tried using my 10w power block and it basically just powers the iPad when using it, didn’t see even one percent charge after using it for like 20 minutes.

I’ve been using an older 12W charging block to charge the new iPad Pro overnight and it hasn’t been an issue. Haven’t paid close attention, but it charged from 20% to 100% within 5-6 hours yesterday.
