NO — Not Recommended
This pairing risks damage or failure to start.
We do not recommend pairing the EcoFlow River 3 Plus Extra Battery EB600 with a Car Buffer Polisher. The station falls short on continuous output by 300W, which risks overload protection trips or failure to start the appliance.

❓ Frequently Asked Questions
Will a EcoFlow River 3 Plus Extra Battery EB600 run a Car Buffer Polisher?
No. The EcoFlow River 3 Plus Extra Battery EB600 cannot reliably run a Car Buffer Polisher. The station outputs 600W but the appliance needs 900W (300W shortfall). The appliance requires 1400W surge to start, but the station only surges to 1200W. Usable capacity is 486Wh, which would yield 0.5 hours if the appliance could run.
How long will a EcoFlow River 3 Plus Extra Battery EB600 power a Car Buffer Polisher?
Even if the EcoFlow River 3 Plus Extra Battery EB600 could run a Car Buffer Polisher, its 486Wh usable capacity divided by the appliance’s 900W draw would only yield 0.5 hours. However, since the station lacks sufficient continuous output, the appliance will not run at all. Consider a station with 1080W+ capacity.
