yaobao or yoobao?


I have several PBs from Yoobao to non branded "30000mah" ones..
Yes, I agree Yoobao's are very good, smaller capacity then the others but proved to hold charge longer.
Though re-charging them took me all night if from zero     
I have no idea how to differentiate ori or non ori, so many versions, so i bought several from several different sellers in ebay to aliexpress..

have to see later if it's good or not
