Some people use portable power stations to run CPAP machines (which treat sleep apnea) and other electronic medical devices while camping. If that’s your situation, we advise getting one of our high-capacity picks to keep your device running smoothly for as long as possible.If you plan to travel, keep in mind that in most cases, portable power stations have to travel by ground. The FAA doesn’t allow passengers to bring batteries rated for more than 160 Wh in carry-on or checked luggage, so you can’t fly with any of our picks.
