>>2457506Problem with those is the weak input, that model only takes 10 watts in. For 20k mah that'd take about 10-12 hours to fully charge iirc. Fine for a weekend trip but if you're on a longer hike and plan to recharge at libraries or whatnot, it'll suck.
I like the concept though, gonna see if there's any that can take more input wattage. I have an old Anker 20k with 30w input, takes about 4 hours to charge.
