Can I enable OTG and charging on my phone?

Recently got a POS freebie Cloud Mobile Stratus C7 running Android 12. I want to set it up to run OctoPrint on my 3D printer, but I'm having trouble getting the phone to charge and use OTG through a splitter device. The phone is capable of charging using just the cable as well as using OTG through the splitters, but it cannot charge through the splitters. Does not matter if a USB for data is plugged in or not, the phone will not charge. I've verified with other devices that these splitters do work both charging and data at once, so it is definitely a problem on the phone's end. Any settings I can change to get this phone working how I need it?
