I wg. Youtube, Twitter & Co. regular battery and charger needs have, I have recently bought the currently equal expensive charger "RAVPower®". This convinced me consistently, also has two charge outputs (2.1A and 2.4A, respectively), so it can even, if necessary, load faster, and has in this point in the lead, especially as the capacity of 13,000 mAh, while the "Foxnovo® FP10" over 10,400 mAh offers.
But:. The "Foxnovo® FP10 charger is considerably narrower and slightly shorter and visually like me better, so I'm going to take this more often on the go A Charger with higher capacity is on paper, of course, a good thing to consider, but is also that it tends to be (still) lasts longer, until it is fully charged -. Here again, the scores for my purposes "Foxnovo® FP10" Who against it regularly takes a lot of power and also charge two devices at the same time wants accordingly, is the " RAVPower® "possibly better served.
Thus, both devices have their place and can convince in practice. Both my iPhone 5S, and the iPad Air can be loaded without any problems fully and I can continue working with it. A downside, however, is that it takes several hours on the 5V input until the "Foxnovo® FP10" is full and therefore extensively for use again.
A note yet to the charging currents: it is fundamentally no matter to which output (1.0 or 2.1A) to connect its devices. The intelligent electronics "recognize" each for themselves which charging current can withstand the unit and throttles possibly just starting. Ie. A contrario., That a higher value does not charge a faster device than it allows. Thus, hence my equipment close at simple charge each of at 2.1A output.
In summary, I recommend the "Foxnovo® FP10". Reasonably priced, easy to handle, very well made and sufficient capacity. Last but not least is the equipment mentioned positively. A beautiful bag with side pocket and a cord "all in one", two-tone, with all major ports on the go and possibly at home - there I but use their own cable - 4- 5 points in the overall assessment, ie rounded up 5 points.
