Aibocn Uranus 20000 mAh Powerbank
First off, I'll explain why I give this powerbank 3 stars. The title states it is "perfect hand feeling". Yes it fits in my hand, but it is heavy and huge! I surely wouldn't call that perfect because I would not like to tote something that heavy and long around in my hands. A male or female with bigger hands might not mind. Next time I will definitely read more details.
For the good stuff, this is a 20000 mAh Powerbank, which can be used several times to charge my cell phone or anything else that needs to be powered by USB. I suggest charging it overnight because it is a big size battery. Obviously it'll need more time to charge. I didn't time it with a timer, but it did take an average of 6 hours to fully charge on a 5v/3a output charger. This powerbank charged my phone from empty to full twice already and still has juice left in it!
Overall, this Powerbank will definitely still be useful for many things for my family, just not what I intended it for. I would suggest changing the title and for those of us purchasing to read more details!
