8 in 1 hub not powered correctly by RavPower? A8383

I just got the new 8 in 1 hub for my IPad Pro 12.9 2018. I like the hub, but I thought I would be able to use a RavPower 60w total USB C supply for it. But the charge signal is not showing on the IPad Pro when powered through the hub. HOWEVER, I have an older 30watt USB C Anker and that does charge the IPad Pro through the 8 in 1 hub.

Is there a reason a RavPower USB C charger would not work with the new 8 in 1?

Thank you for writing to us and letting us know your concern.

Please check if the output of the connected port on your RavPower 60w total USB C supply over 30W. Please note that A8383 hub supports up to 100W (minus 15W for operation) pass-through charging. If the connected wall charger only supports 20W, then your IPad Pro only can get 5W, the charge signal won’t show on the IPad Pro too.

If you need further help, please contact us at support@anker.com. Thank you!
