Replacement USB-C charger iPlay 70 mini pro

Does anyone know when I can get a replacement USB-C charger for the iPlayer 70 mini pro?

I have not been able to find any official Alldocube replacement chargers for this tablet in AliExpress.

Any recommened alternative USB-C chargers which support fast charging for this tablet?

Thanks.

It can be replaced by another PD 18w charger.

Strange when the original PD charger that came with this tablet is 20W with the text on it stating that it supports the following max power configurations: 5V*3A=15W, 9V*2.32A=20W, & 12V*1.67A=20W.

However when I fast charge with the original charger, my USB-C tester shows it providing: 10.9V*1.62A=17.66W.

I have attempted to use 3 other 20W, 45W, & 60W PD chargers which also can support these power configurations or higher: 5V*3A, 9V*2.32A, & 12V*1.67A. But none of these 3 alternative chargers are able to fast charge this tablet. Perhaps there is some issue with the PD negotiation that makes some PD chargers incompatible with this tablet.

If you have a link to any specific PD charger for sale, which is known to support fast charging with this tablet, please let me know. Thanks
