Seems like a very good deal for this model and you can add solar panels to it which is nice. Does fall into a bit of an odd niche though, where it's both too small and too big in some ways.
Have the river 3 as well for AC needs and larger ecoflow 2 for power hungry devices.
DC-only eliminates the 10-20% AC/DC conversion efficiency tax. Most modern devices use DC natively. Those asking for an AC outlet are probably plugging a "wall wart" AC/DC converter plug when they should be using something like this and running DC to DC.

LFPO is safe enough as a battery chemistry and dense enough that it meets most applications, and its stable voltage curve makes design & implementation much simpler. Sodium weighs a ton due to its lower energy density and has a very wide voltage curve kinda like SLA batteries.
Missed it when it was $110 during the holidays and it sold out, pretty sure it will sellout at this price as well.
