GoKawiilCNET Lab Test: Fossibot 3600 Pro Runs a Fridge Longest Among 19 Power Stations
CNET tested 19 large and extra-large portable power stations by connecting each to a standard refrigerator to see how long they could sustain it during an outage. The Fossibot 3600 Pro led the pack at 44.65 hours, followed by the Oupes Mega 5 at 43.72 hours, while the Oscal Power Max 2400 lasted just 12.58 hours despite similar categorization.
GoKawiil's interpretation of the reporting above, not reported fact.
The results challenge the assumption that keeping major appliances running during a blackout requires an expensive whole-home battery setup. They also show that battery capacity alone doesn't predict performance—efficiency and design matter just as much, since even the large-capacity Anker Solix F3800 Plus underperformed relative to smaller units.
- Fossibot 3600 Pro and Oupes Mega 5 topped the fridge-runtime rankings among 19 tested power stations.
- Bigger battery capacity doesn't guarantee better performance—efficiency varies widely, as seen with the underperforming Anker Solix F3800 Plus.
- Budget-friendly, smaller power stations can often handle major home appliances without needing a costly whole-home battery system.
