Answer
Can the EcoFlow RIVER 3 Plus run Lasko 755320 ceramic heater, low?
Runs
Runs. The 900 W element fits X-Boost at 1,200 W, which is above the 600 W continuous rating. Voltage can sag in that mode, so a heater may put out less heat than the nameplate. Estimated runtime: about 16 min.

What watts were compared?
Station continuous output is 600 W. No motor-surge rating is applied. Appliance running draw is 900 W. Published appliance peak is 900 W.
How was the runtime calculated?
286 Wh × 0.85 = 243 Wh usable, divided by 900 W average draw.
Where did the numbers come from?
Spec table: 286 Wh, 3 outlets, 600 W total (surge 1,200 W, X-Boost 1,200 W), 10.4 lb, LiFePO4, 3,000 cycles to 80%. Page copy says X-Boost continuously handles 1,200 W heating devices. The shelf price on that page was not used; launch price was not stated. Same Lasko listing: energy output 900 W to 1,500 W. Low is the 900 W end of that range. 7.5 A × 120 V = 900 W.
