I’m only half kidding. I’m a bit of a prepper and I have lots of powerbanks and devices that charge from USB but besides idling my truck I really had no other way to charge any of them in case of a long-term power outage which seemed a bit of an oversight on my part.
Not like this solves the issue. 30 watts (under ideal conditions) isn’t much but it’s a start.
I bought the Jackery Explorer 100 and am coupling it with a 45W panel. I figured the Jackery would be better for solar than an average power bank, because they already package it in a bundle with their own panel. BUT since both USB C ports on the Jackery can do both power in/out, I think the Jackery can actually get confused about whether it’s supposed to be charging or discharging, when the panel is running at very low output… … at least, that’s how I interpret having returned to it and seeing it discharged when connected to the panel.
Out of curiosity, I’ve been wanting to get a jackery for camp trips an such, how is the 100w model? I keep eyeing the 2000w version but the price of it is absurd.
