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.
Each power tool manufacturer uses their own proprietary battery and I don’t want to be locked into a single brand of tool or have to buy a shitload of adaptors or batteries.
Tbh its tempting to go with manual tools instead. Return to tradition and use a scythe instead of a strimmer.
