If your hanging this unit with the included carabiners the pouch is upside down and anything you have inside falls out

It is pretty rugged and holes in the corners and the accompanying clips allow it to be attached on the outside of a backpack

I connected the solar charger panel to it and within a half an hour it was charged enough to have made a call on it if id needed to call 911 since the phone is not currently connected to the network

Works well even in not ideal condition doesnt seem to need direct sunlight to charge even on a partly cloudy day it was charging my phone the only drawback is it will drain your battery if its not charging because the usb on it lights up when its in the sun meaning its being powered and if there is no sun it will draw on your battery

This unit does what it says itll do provided one doesnt expect too much from its wattage at this price point
