Charging IPAD whilst connecting to Mixer!

Hi guys fairly new to all this and really struggling to find a viable solution to charging the iPad whilst using the C port of iPad to connect to mixer for singing gigs. I tried a c spilter but didn’t seem to work and then with a friends iPad used a magnetic charger with the three dots on the back which was ok but in looking at buying a new iPad the magnetic charger option only seems to cover the expensive models, does anyone recommend a c spilter make/model that actually works?

Thank you
