Functionality:
The device looks very noble by the matte casing. The indicate the battery level via an LED display indicating the state in percent. There are 3 USB ports for charging the devices (iPad and iPhone at the same time, etc.). In addition, is still a small LED lights fitted, which is turned on by double the ON / OFF button on / off. Very handy as emergency flashlight.
Bottom line:
I have the RAVPOWER BANK 18200 mAh for several months now in continuous use. Because I go fishing a lot and that over several days or 1 week at a also happened, I have to be honest. TOP 5 Stars. I have the RAVPOWERBANK 14000 mAh and have been too well satisfied with. But 18200 is of course again a number better. The small white LED lights on the housing is really useful. Who much in nature, and do not want to give up a bit of luxury, the Power Bank should purchase. So from me full 5 stars for this ingenious product.
