Need Help Statting a Magical Interdimensional Teleport Cloak

[Phantasm]

What I have for the description reads:

The cloak can be used to teleport the wearer and up to four other people through another dimension to any place on Earth. The wearer is not able to use the cloak to teleport inside places warded by magic. The cloak is reportedly able to travel to most other dimensions, though this is as yet unconfirmed. The teleport may not be instantaneous, and the wearer and any passengers may use the dimension connected to the cloak as a kind of way-station, remaining indefinitely if they so choose.

Is this Warp, Jumper, or both, and what kinds of modifiers would I need? I'm leaning to Mental Carrying Capacity (Supers, p. 29) combined with Modified Capacity (Static) (Psionic Powers, p. 18), but I'm not sure that's legal since Modified Capacity as written is meant for Exoteleport.
