This thread is making no sense to me.

It jumps from an iPad to an Oppo android device(Im guessing) and from an explorer to a prime.

I have no idea what the actual end game is.

To be clear, the explorer 2 works with an iPad or iPhone if you use

with external power connected since the USB internal to the iPad/iPhone doesnt have enough current on its own to power the explorer.

I dont have a prime so cannot comment. I also have no android, if thats what an Oppo A53 is, so again cannot comment.

Perhaps if you explained what you are trying to achieve, more targeted advice would be forthcoming. For example what version of iPad are you using etc etc
