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.
Oh you want to go with CORDED tools. There I couldn’t give you direct guidance because the difference in voltage/current standards, I don’t know what kind of amperage or wattage your collection of tools would require, especially since you haven’t bought them yet.
I don’t have the problem you’re facing though with non-standard batteries; I have a pretty large collection of cordless tools that all take the same batteries. From a chainsaw and lawnmower to a miter saw and palm router. I’ve got like 10 of the batteries in various sizes and about 20 tools. The weirdest one in my collection is a drill battery powered soldering iron.
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.
