So most airlines in the states limit batteries to less than 160W unless u have some sort of medical condition and requires permission to get a larger battery onboard. If a battery outputs 5V I'm limited to a capacity of 32000 mah. So what's the largest capacity battery that I can bring on a plane that is less than 160 watts and will charge my switch the fastest? I can't find like a sorting tool but given the small 160 watt limit I was hoping for lots of options. Thanks for any help.
