Simultaneous-output conditionsManufacturer sharing limits and unresolved allocation details.

Recharge workflowThe input connection and conditions behind the advertised maximum. A compatible high-power wall charger may be separate.

EcoFlow's EU table lists 140 W recharge through the cable or C1 and 280 W total through USB.

Important qualificationsThe evidence boundaries that affect this comparison. Check the exact model and current support or recall instructions before relying on the package. | EcoFlow states over 80% capacity retention after 300 cycles and says airline rules vary by region and carrier. App and Wi-Fi features are optional. These are manufacturer claims, not measured delivered energy, a carrier approval or safety certification.Source · 2026-10-21EcoFlow: RAPID Pro Power Bank 27,650mAh 300W US product page (EF-RAPIDPRO27K-US)Checked 2026-10-21.

| Questions to check before buying | The US page does not break the 320 W input down by port, and its multi-port allocation diagrams were not available as text. The US box contents are not listed; the flannel bag in EcoFlow's EU box list is not assumed for the US package. |
