Having already tested a Ravpower 10400 mAh battery (which I gave to my family and friends), I took a 13000 and 16000. Here is my opinion on 16000:
This battery is the top!
This is exactly the same as the version in 13000mAh (same size, same color, same functionality), but higher capacity in the same footprint!
Functionally, it is equipped with 2 charging ports (2.4 A and 2.1 A). The capacities of the ports are shown in brackets, can not go wrong! And anyway, the port adapts to the device plugged into it (Ismart), so no worries.
The space between the USB ports are not gene the establishment of two cables.
Aesthetically, it is sober (I have the black model) and the charge level is indicated by blue LED.
Regarding the content you will find:
* Although the battery with 2 charging ports iSmart
* Carrying pouch (light and airy) which may also contain associated cables
* USB cable 60 cm long that, and that's not always the case, also works for data (some cables are only charging)
* A second shorter cable
* Charger (big plus)
There is provided a charger capacity 2A. The charging time is long, but it's normal since the battery capacity (in the order of 9-10 h).
I tested the battery with the Xperia Z2, a motorcycle G 4G, tablets and CDisplay of no concern. For information, with a load I could do:
3 charges (about 90%) of my Z2 and one of my motorcycle G without intermediate charging (without using the phone while charging).
Charging times are identical to the original chargers.
The little bonus is the integrated light! She was present on my small 3000 mAh battery (always with RavPower) and is always essential! Convenient for plugging in the dark, to have a light practice on either!
In conclusion, very satisfied!
I do not intend to get around without a battery in my bag, whether for my phone, tablet children ... use my gps that no longer holds the battery walk ...
I recommend the RavPower products, never disappointed for my part
