As if getting on your flight couldn't get any more annoying, airlines are beginning to ban dead cell phones due to recent security threats. With how much we rely on our smartphones these days, it's probably the last thing you want to be without when you're flying out of the country. We've rounded up five of our favorite battery options to give you a little peace of mind on your travels.
Mophie Battery Cases
A good battery case is always a great option. It's always on your phone so you won't have to mess with an external battery and when you need some juice, all it takes is a flip of the switch and you're ready to go. Mophie has been the household name when it comes to battery cases and they've got ultra-slim options such as the Juice Pack Helium ($79) that gives you an extra 80% of battery life and even extra storage and a full charge with their recently released Space Pack ($149-$249).
PhoneSuit Flex Pocket Chargers
If cases are too bulky for you, PhoneSuit's Flex Pocket Chargers ($59) let you keep the thin profile of your smartphone with a compact battery pack that plugs right into the bottom of your phone. Available for both the iPhone and phones with Micro-USB ports, the 2600mAh batteries can fully charge your phone and with its integrated Lightning or Micro-USB tip you won't have to carry around an extra cable.
The Anker Astro3 ($45) is all about capacity. With a capacity of 12000mAh you'll have enough juice to charge an iPhone six times and with three USB ports you can even charge your tablet or any other portable device. It also has a feature called "PowerIQ" that can detect the type of device and maximize its charging speed.
Unu Ultrapak Tour
The speed demon of the bunch is the Unu Ultrapak Tour ($59-$99). These batteries are a bit of a gamechanger in the category with what's claimed to be the world's fastest charging battery pack. In just fifteen minutes the battery can quickly fill up with enough capacity to charge your phone for a full day (2000mAh) and in just 95 minutes the pack can reach its full capacity of 10000mAh. The Ultrapak also comes in a more portable 3000mAh size and both feature LED displays that indicate charging time and battery life.
