Just charge it, u don't need to drain it really.
And u can use any usb cord you like, it doesn't matter, I rarely use the ones that came with it
Sent from my Sprint Samsung Galaxy s3 with a 7000mah extended battery... Because I'm not a chick with dainty hands or an HTC one user![]()
I am not goona use the cables that comes with it, doesn't seem to be good quality. I am just going to drain all of it's battery first, just charged my dad's iPad 2 and my Galaxy S3 (partial charge, from 44 to 100%), still have around 5-25% charge on the portable battery charger (1 light indicating). I guess I will keep you guys updated once I returned my trip from China, if you guys are willing to wait for a month lol.
