Runtime = 910 Wh usable (independently measured) ÷ the appliance's average draw. Fridges and freezers average their daily energy use; everything else counts as running the whole time. "No" means the load exceeds this model's continuous output or surge rating. Methodology.
Recharge with solar
Solar input: 11–60 V, 15 A, up to 1,000 W (XT60i).Manual: 'The XT60i input port(s) of the power station supports both solar charging and car charging' and use an 'EcoFlow Solar to XT60i Charging Cable'. The spec table labels it 'DC Input Port (XT60)'; XT60 plugs fit an XT60i socket.Product page specs: 'Solar Charging | 2 ports, DC Charge Input, 11V-60V 500W Max*2'. Both ports are shared with car charging. Panels that fit, fastest first, one panel at a time; days use Dallas, TX's sun (5.4 peak hours a day on average, 4.37 in December). Two or more panels charge faster, up to this station's 1,000 W input limit.

Real-world watts = panel rating capped by this input's current limit (× the panel's voltage at max power) and maximum solar input, × 75%. Peak-sun hours to full = rated capacity (1,024 Wh, since charging fills the whole battery) ÷ real-world watts; days = those hours ÷ peak sun hours per day. Sunnier and cloudier cities are on each panel's page; full method in the methodology.

Usable capacity = this station's usable capacity + each battery's independently measured usable capacity, or 80% of its rated capacity where no test exists ("est."). Runtime uses the same formula as everywhere else on the site. Battery specs come from the brand's official pages.
