July 17, 2024Another deep dive into power banks
What specific devices are you prioritizing for charging? Phone, GPS watch, headlamp, or are you running other electronics like an InReach? if you're doing longer stretches between resupplies (thinking northern sections or some of the more remote stretches), there's an argument for going higher capacity even with the weight hit. Something like this one gives you 20,000 mAh but you're looking at nearly a pound. Only worth it if you're doing 7+ day stretches or running power-hungry devices like satellite communicators.
