Phone Battery Stand

When I'm camping, my phone is my entertainment centre, usually plugged into a power bank. This stand holds the a phone or small tablet in landscape or portrait orientations with a cable plugged in using the weight of the power bank for stability. The base has sockets to receive the prongs that hold the phone. Different sized prongs accommodate different thicknesses, for example when I have the magnetic battery pack on the back of the phone. I remove the prongs for packing. This design fits my phone and power bank, but there's nothing so complicated about it that anyone couldn't make one for their gear.
