As regards the aspect of the battery weight etc ...
She inspires and strength, for a very decent size and weight overall.
Indeed it will be difficult to reduce its size and weight, for such capacity.
The small bag supplied're more for transportation during your trip ...
the supplied cable seems a bit low, but in the end it was those of our camera (and are very easy to find in case).
Anker choosing these really focus on the quality of the battery itself.
It contains 5 cells "last generation" Samsung lithium ion, with a capacity of 3000 mAh per cell. These cells very good shows Anker's attention to the choice of the quality of the selected component.
the plastic coating of the latter, are of very good quality.
I do not regret my purchase and would recommend.
the final Anker batteries are justified reputation and after sales service are excellent.
Finally if you are like me looking for a quality product this battery Anker small price are what it takes you.
to buy eyes closed.
Ps: I do not often comment on the product I bought but given the seriousness and speed of service after sales Anker. I took the time to make one.
