Review: Kenwood BN-RK800 portable power station $200

This Kenwood BN-RK800 portable power station ran my (Energy Star) fridge for 7h 9min, delivering 530 Wh of power (via the AC inverter output to the fridge). [This is only 63% of the claimed 800 Wh battery capacity, most likely due to efficiency losses in the inverter or a battery that isn't quite at the rated capacity.] When I ran it all the way down, it reset and got confused about it's battery capacity, initially saying it was at 100% charge level (and refusing to re-charge). After I drew a little power out via the 100 watt USB-C port, it started to charge (at the normal 450 watt rate). It re-charged for just above 2 hours and took 890 Wh to fill the battery back up, in line with the 800 Wh battery capacity specification. The 3x AC ports are driven by a 700W max inverter (1,400 w surge for brief periods of time). It can also deliver 120 watts out of a 12v car "power port". It has 2x USB-C power delivery ports (100W and 30W) and 2x USB-A quickcharge ports (5,9,12 volts, 18 watts max per port). It also has a DC input / charging port (12-24 volts, max 240 watts, draws 8 amps so only charges at 96 watts on 12 volts). The closest product comparison I'm familiar with is the Jackery 1000 (v2) has slightly more capacity (1000 Wh vs 800) and a significantly more powerful inverter (1,500 watts vs 700), but also costs twice as much.
