I've used this a few times and it works great. I have a sleep apnea device and have always had trouble camping in a tent but now with this setup it's not a problem because I have the power. I was able to easily charge my 2 phones and my pad and also keep the sleep machine running. I would also recommend a solar panel. He kept the portable battery fully charged. It's a great environment and I think everyone should have one, especially when life happens and you have to get out of a jam. The first thing I take with me on a hike.
