Side look and practical: this external HDD surprised me by its delicacy. The finish is very beautiful: LED, blue row of small lights indicating the load, etc. all coupled to a well assembled design: matte plastic that inspires strength. I'll let you take a look at the pictures users ...
Then the plethora of adapters and cables is always nice. Finally, the storage case allowing to drag ALSO its cables is really interesting: it absorbs (some) things and closes. I find it very convenient to also slip in its cables rather than letting them hang.
Technically: I said it all before: 14000 mAh ... we are in extreme ultra portable batteries! But the advantage of such a charge is that we will soon surprised to use even at home, never to seek outlets ...: D
The battery has 2 outputs, the amperage of a classic iPhone and one for iPad / tablet. You can check compatibility with your original chargers. And it may well charge 2 devices at the same time !! A true resort!
Finally, I think the charge for iPhone as iPad is very fast.
It is beautiful, not very heavy, the size of a smartphone and has a nice case (it is always better than nothing!) ... And it is solid, because I've always thrown to the bottom of my bag for 3 weeks! I recommend for foodies of battery: with it we forget everything and is heated 3G: D!
