DB solution for hybrid-mobile-app

I am going to build hybrid-mobile-app with Ionic, Angular and Cordova and port it to Android and iOS. One of the main features of the app will be offline storage/capability to store and view app content offline.

Content that I want to save in local DB may be even over 50MB, so local storage is not an option.

So far I found sqlite and indexdb. But I wonder if any of you have previous experience with similar problem to solve and could suggest some other options? Or maybe which option (sqlite or indexdb) will be better solution for my app?
