This station made the list for one key reason: it’s designed to power a continuous positive airway pressure (CPAP) machine, a device commonly used by people with sleep apnea. When paired with the ROCKPALS DC converter, this battery can power a CPAP (with the heater and humidifier turned off) for about three nights. It’s heavy, at more than seven pounds, it’s heavy, which makes it best suited for situations like car camping or providing reliable power during a blackout rather than hiking trips, but the extra weight does carry about three times the amount of power as the Goal Zero Sherpa. It’s compatible with any solar panel that supports MC4 style connectors, but also comes with a 12v cable for car charging. Bonus: it has built-in LED lights.
