    Can PowerCore II Slim 10000 be taken on board airplanes?
    "Yes, all external batteries with a capacity lower than 27027mAh (100 watt hours) can legally and safely be taken on board airplanes. To calculate an external battery's capacity in watt hours: (Battery mAh Capacity X 3.7)/1000. Here are the relevant requirements quoted from federal transportation security rules: Effective January 1, 2008: Passengers may carry consumer-sized lithium ion batteries (a.k.a. rechargeable lithium, lithium polymer, LIPO, secondary lithium) with no more than 8 grams of equivalent lithium content or 100 watt hours (wh) per battery. This size covers AA, AAA, 9-volt, cell phone, PDA, camera, camcorder, Gameboy, and standard laptop computer batteries. Passengers can also bring two (2) larger lithium ion batteries (more than 8 grams, up to 25 grams of equivalent lithium content per battery) in their carry-on. This size covers larger extended-life laptop batteries. Most consumer lithium ion batteries are below this size."
    Can PowerCore II Slim 10000 be used for international travel?

    Does PowerCore II Slim 10000 work with the new iPhone 8/8+ and iPhone X?
