i seriously dun think it is even close to 60% for a china 18$ battery claiming 12000mah.. Anyway, for all lith, expect 80% not 60%..
I would rather get something from more reliable brands than something un proven and most likely fake capacity. ANother problem with this kind is that maybe use less than 10 times, the internal battery cui already..\
Finally take note, if we want decent charging time, we need to charge at 2A. most of these batteries only charge at 0.5A. Meaning, if you take 2hr to charge your note with wall charger, u use those cheap power packs u need to charge 8 hours. kinda defeats the purpose
This yoobao supports 1A and 2A charging and is reliable brand... One Cent One Good (chinese saying hahaha) I got one for 3 months alrdy. loving it. charge fast, last long!
