Great product that is compact and light weight. I wouldn't feel I was wasting space by backpacking with them. This has a lightning port, so make sure to order the battery pack. I am holding off ordering one as I have one coming with my Hot Pocket soon. But, it does fit in the new iPhone wall charger ports, so that's cool if you have electricity. I could easily use this now while car camping with my wall charger. As with everything, the product is well-made and SMr's customer service is top-notch!
