Yes, all EXCITRUS power banks can be taken on board airplanes.
According to ITAT requirement, all external batteries with a capacity lower than 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 3.7/3.6)/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.
However, this issue of compatibility is about to be a thing of the past with the introduction of the USB Power Delivery Specification. USB Power Delivery (or PD, for short) is a single charging standard that can be used all across USB devices. Normally, each device charged by USB will have their own separate adapter, but not anymore. One universal USB PD will be able to power a wide variety of different devices.
The biggest advantage is that USB Power Delivery has increased standard power levels to up to 100W. This means your device will be able to charge much faster than before. Also, this will work for most devices and will be great for laptop users, Nintendo Switch users.
Another great feature of USB PD is Power delivery is a two-way street: One of the most exciting developments in recent USB technology is two-way charging. This means that, for example, your tablet could be used to power a portable hard drive via the charge port. This functionality unlocks bold new possibilities for consumers and manufacturers alike.
Power delivery doesn’t discriminate between devices. PD is backward compatible with devices designed for other USB standards, like 2.0, 3.0, and type-C. It intelligently delivers an appropriate amount of power based on the architecture of the device to which it is connected. Ensure devices are not overcharged and will only provide the necessary amount of juice needed. While most smart phones won’t be able to take advantage of the added power, many other devices and computers will be able to.
