    This was purchased as a gift to my son who lives in Alaska in an area that, due to weather, has a few short duration power events per month. He has been using his cell phone and a few other devices and is charging all of them with this device to draw it down to see how much he can recharge on one charge of the device. I says that it fits his needs and although bulky and heavy and it will easily take care of all of his devices on 2 to 3 day camping trips in the spring/summer.
