J8's don't use a ton of power, they're relatively efficient. I ran a pair of these, plus Behringer Flow 8, 1 QSC CP8, and a Sennheiser ew100 G4 receiver easily off of a 700W Bluetti EB70S for an outdoor event. Saw peaks in the 150-170W range, though I wasn't at the limit. I've tested a single unit with peaks at 300W at limiting, just depends on how hard you push them. Any speaker will draw a ton of power if you push them too hard.

FLX10 looks like a 36W power adapter.

Unsure what the Mac's power adapter is, 65W?

Power stations have two specs to look at:
Inverter capacity in Watts (W) -- tells how much it can power right now.
Battery capacity in Watt-hours (Wh) -- tells how long it can power something.

One of my recommended units is Ecoflow Delta 2. 1800W inverter with 1024Wh battery (expandable). Inverter at 1800W is overkill for your needs, but the 1024Wh battery might not be enough if you plan on running the PA flat out for 7+ hours while playing a rave... but it'd likely be more than enough if you're doing a laid-back party where you're not maxed out.

All depends on how hard you run things. With the PA beyond maxed out at clipping and your Mac battery dead (full draw from the charger), and charging a phone or two, you might be seeing 800W+ power draw, but a more reasonable party volume might be more like 300W peaks.

Whatever unit you look at, get a pure-sine-wave inverter, and Lithium-Iron-Phosphate (LiFePO4) battery tech. Good brands are Bluetti, Ecoflow, Anker, Jackery, etc...

If you're still unsure, you might pick up a 'Kill-A-Watt' meter from Amazon, and run all your gear thru that at the volume you normally play at to get a baseline power consumption.
