Check out my video on powering your phone and tablet when you can’t plug in.
If you find yourself nowhere near an electrical outlet, but need to charge your phone or tablet, then this power supply is just what you need. It will quickly charge your devices and get you going again.
I purchased one of these when I was taking a lot of photos with my phone at a Pompeii exhibit, and drained my battery. Since then, I’ve used it when in nature and at events where I can’t charge my phone easily. I just plug in the power supply to my phone to quickly charge it up.
