Power Strips for 9th Gen Ipad 20W USB-C Chargers

Our school purchased 9th Gen ipads for 4 of our classrooms. Each room has a cart to store and charge up to 30 ipads. We are attempting to re-wire the carts for the new, larger USB-C chargers, and we found

that the size and orientation of the new chargers do not fit on our existing power strips inside the cart.

What we need is a power strip that is oriented like the one below, has 15 outlets, and is no longer than

26 inches. Has anyone else ran across this problem? I have looked for power strips with USB-C outlets,

but see ones with only 4, and they might not charge Apple products.
