I like the form factor with two wheels and a retractable handle.
Doesn't this constitute the world's smallest microgrid? With two battery packs Y-ed together to provide 240V, enough to power to run a clothes dryer.
There exists also an Ecoflow River line with LION batteries where the Delta line has LiFeP04.
I'm actually thinking about a VW Beetle EV conversion with two or three of these for the battery pack. You could pull one out at a campsite and still have enough vehicle power to scoot around.
Now I'm thinking one Delta Pro cradled in a (rat-rod) beam extender for a GM eAssist hybrid altermotor conversion on the Beetle engine..*
Someone stop me before I think again.
