If you're not looking for a case, I'd recommend the Hootoo Travelmate Elite. It's a battery pack, but it also allows you to (I'm sure I'm getting the terminology wrong here) rebroadcast a wifi signal so that all of your devices can long onto it. I use it for hotels, so that I set ip up & then connect my devices to it, and every time I come in/out of the hotel, my devices connect & I don't have to retype in the hotel password every single time. It's also great for hotels that only give you one or two logins per hotel room. You can log in with the hootoo, and then connect all of your devices to it & it still only shows up as one device.
