I've never met anyone who is completely satisfied with the battery life of his or her mobile device. And now that the FAA has given the green light to using electronics during takeoff and landing, you'll need event a few minutes more of juice.
The good news is there's a plethora of battery packs (or juice packs) that now offer you many ways to conveniently carry extra power with you. Following are my seven favorite juice packs that, when paired with a mobile device, are great not only for long flights, but also when you're out and about, even in rough environments.
Note that I haven't officially tested and reviewed these devices (at least, not all of them) but via personal and collective experiences, I consider these among the best on the market. In any case, if extra battery life for a smartphone is what you want, you won't go wrong with any of these.

The Samsung LTE HotSpot Pro
The Samsung is actually not a juice pack; rather, it's a mobile cellular modem that brings the Internet to up to 10 Wi-Fi-enabled devices (and it works very well in that regard). However, this is also the first device of its type that comes with a very powerful 3,100mAh battery that, apart from giving the device itself some exceptionally battery life, can also work as charger or a juice pack for any smartphone and tablet that uses the standard USB charging. In my testing, the Samsung, when fully charged, packed enough juice to bring an iPhone 5 from empty to full and still had some left. More impressively, it did that while still working as a mobile hot spot at the same time. If you're also looking for mobile hot spot, the Samsung definitely makes an excellent juice pack solution.

RAVPower Element 10400mAh External Battery Pack Charger
