iXpand Memory Case

Expand your iPhone's memory with a case

I always want something like this, but the main problem with all of these types of products is they don't work with the native iOS Photos app. Instead it requires a 3rd party SanDisk app and therefore won't sync with the MacOS Photos app.
I really like the clip on battery pack for the back too. I've started using a portable charging pack for charging my phone at night. Let's put my phone anywhere and not need it to be tethered to a wall. I can see myself using this similarly.
perfectly designed to solve the key problem.
