Using a 30 WATTS Charger with the iPad Pro ?

[triangletechie]

Aside from my MacBook Pro and iMac, everything else is charged with the 18 watt charger.

I actually used two different third party chargers from reliable manufacturer having power delivery output: one was 35W and the other 61 Watts capable of delivering 5,9, 12, 15 or 20 volts as per need. I also used a non Apple USB C cable of a high quality. The iPad pro 12.9 4th generation took between 14.4 and 15 volts with a total power peaking at 34.8 watts. So indeed the iPad Pro can take a higher voltage and can work with several chargers. iPad did not recognize Quick Chargers and drew 5V at just around 1A (5 Watt). Conversely, the Apple provided charger could work with my Note 10 Plus at fast charging (5 volt only, not 9 volt, but at a higher current) so that the overall power delivered to cellphone was over 10 watts. I did not test the iPad pro with the Apple 30W charger but am sure it will charge the device fast!

Are you using it through the Magic Keyboard port?

Fast charging on iPad Pro 12.9" 1st Gen works well on USB-C Apple chargers with 15V profile, and with an Apple original USB-C to lightning cable. I can only find one full-on, attractively priced charger on the market as of June 2020, which is the 61W A1947 for around £35 second hand:
