I dread all those extension cords when using the hedge trimmer and other stuff. I found that if I connect the E-bike battery of a friend to it the hedge trimmer runs somewhat slower but reliably. It had 53V DC.Those machines contain brush-type universal motors, probably with a compensation winding but not sure. Is is safe to run these with 40-60V DC over long periods of time or is there some sort of motor pathology that could hit?If ok I could build a stack of 12-15 Li-Ion 18650 cells which, at 1.5A to 2A, should afford me about 45min of runtime. Or maybe build three sets of 4S or 5S batteries I could use for other stuff and then connect those in series when bushes need to be trimmed 2-3 times per year. With reverse-polarity protection diodes, of course, so I won't fry their individual BMS'es.

If there is permanent magnet inside, then yes for wearing.I would get an AC inverter. 48V DC to 120V AC can charge an EV as well.

Running garden tools on 40-60V DC instead of 120VAC?

it's a single box with battery, charger and inverter all in one, with 120V, 12V and USB outputs though 250W might be a bit low

This one has 300W but IME such small inverters trip off all the time because most power tools have a much larger start-up power draw. That is one of the advantages of direct DC, no trip-off.

Even regular draw at 120VAC is higher than that. My hedge trimmer and the weed whacker are the most used tools here and they each pulls 4 amps at 120VAC, almost 500W. On 50V DC that drops to about half yet the power is still reasonably ok. Not for a professional gardener but for me.

It is almost misleading withthe word Generator. I think it does have solar cells for charging, but they would take a long time and not at all in the night.

I would think that genertor would mean a useful generaor that would be gas or propane powered.
