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.
Might. Might not though. Probably doesn’t, because then it doesn’t sound as good to potential buyers.
Usually it does and it will be ideal conditions. So it still won’t make 30w but it will do much better than 8w.
