The battery fells well made, it is 92x98x29mm (average) doesn't fell too heavy (at least to me)
It is rated 11000mA but at 3.7V which is the naked dry truth but somehow I was expecting it rated at 5V (the output voltage), aaah the magic of marketing, still 40.7W never the less

There is an unboxing video in their web page here

Mine had a retractable USB to DC connector a mini USB adaptor and WHAT IT LOOKS LIKE A Nintendo DS adaptor
It didn't include the Galaxy tab charging tip (the one used to charge from a PC) but thankfully I had one bought some time ago for 3 or 4 quid
Does it charge at the 2a required by the tab?
the output is rated 1A but it does (the tab does not require 2A that is the max rated charge)
indeed it charge the TAB, it charged mine from 70% to fully in I guess under an hour?( I lost track doing stuff and when checked ithe tab was charged) , this is with the screen off but wifi and bluetooth ON
Would I buy again with what I know now? Yes, but i will need more time with it to see its true performance
All in all I am pretty happy with it

, but if someone is going to purchase one, remember ask for the Galaxy tab tip, or if they do not provide it you need to get one from ebay or somewhere ,
it charge my tab without the tip but Im pretty sure that it will be slow (just as if i plug the tab without the USB tip to the PC)
