This is among one of the best power banks I have tried. The reason why is I don't have to use a USB port or even plug it in. All it needs is solar power from the natural sun. So this would be great to take on hikes or anywhere you would be away from electricity for awhile. As long as you have sun you have power for the power bank. It's also a great blue color and I love it. Charges good and you can use the USB that comes with it or use your own. You have a compass on the power bank and a light all you do to activate the flashlight is you double click the power button. This is a need device.
