Specs side by side
| Spec | EcoFlow RIVER 3 | Jackery Explorer 300 |
|---|---|---|
| Rated capacity | 245 Wh[source]Manual: 'RIVER 3/RIVER 3 (10 ms UPS): 245Wh 19.2V⎓12.8Ah'. A separate 'RIVER 3 (230)' version is 230Wh. Data is for the standard 245Wh RIVER 3 (model EFR705). | 293 Wh[source]Original Explorer 300 (293 Wh). Jackery also sells the separate Explorer 300 v2 (288 Wh) and Explorer 300D (288 Wh), and earlier sold the 300 Plus (288 Wh); those are different models with different specs. |
| Usable capacity (measured) | 203 Wh[source]The Solar Lab: a 273 W load 'lasted 45 minutes' for 'an efficiency rating of just about 83%'. 83% of 245 Wh = 203 Wh (calculated; 273 W × 45 min ≈ 205 Wh). US 120 V unit. Other result: StorageReview 'measured the full discharge power of 210Wh' with a 300 W fan load (storagereview.com/review/ecoflow-river-3-review). | 247 Wh[source]OutdoorGearLab measured 247 Wh delivered (about 84% of the 293 Wh rating). |
| AC continuous output | 300 W[source]Manual (US): '120V~60Hz, 300W total'. X-Boost runs heating/motor devices 'rated at up to 600W'. | 300 W[source]'293Wh Capacity, 300W Inverter (500W Surge)'. |
| AC surge output | 600 W[source]Archived official US page specs: 'AC Output | 2 outlets, 300W total (Surge 600W, X-Boost 600W)'. The manual table gives no surge figure. | 500 W[source] |
| 240 V output | No[source]Manual AC output (US): '120V~60Hz, 300W total'. | Not publishedOfficial US page states only '293Wh Capacity, 300W Inverter (500W Surge)'; no AC output voltage in page text and no official manual PDF found on jackery.com (user-guides page lists none for Explorer 300). Third-party listings say 110V, but those are not official. |
| Battery chemistry | LiFePO4[source]Manual: 'Cell Chemistry | LFP (LiFePO₄)'. | Lithium-ion[source]Official page says 'lithium-ion battery' without naming the cell chemistry (not LiFePO4). |
| Cycle life | 3000 cycles to 80%[source]Manual: 'The battery maintains 80%+ SoH (State of Health) after 3000 cycles at 0.5C/0.5C at 25°C (77°F)'. | 800 cycles to 80% capacity[source] |
| AC charging | 320 W[source]Manual: 'Maximum AC Input Power: US/JP/BR: 320W'. Archived US page: 'AC Input 320W, 0-100% in 60 min'. | 90 W[source]Charges from the wall via an included 90 W adapter (not a direct AC input). Official page: 2.5 h recharge when combining the 90 W wall charger with a 60 W USB-C PD charger. |
| Max solar input | 110 W[source]Manual: 'Solar Input | 11-30V⎓8A, 110W Max'. | Not publishedOfficial page gives only a solar charge time (SolarSaga 100: 0-80% in 3.5 h), not a maximum solar input wattage. |
| Expandable | No[source]The manual's full port list (items 1-12) has no extra battery port, and the specs list no expansion. Inferred from the port list; the manual does not literally say 'not expandable'. | Not publishedOfficial page does not state expandability either way. |
| UPS / EPS switchover | 20 ms[source]Manual: 'RIVER 3 / RIVER 3 (230) The power station supports emergency power supply (EPS) with a transfer time within 20ms.' Only the separate 'RIVER 3 (10 ms UPS)' version switches in 10 ms. | Not publishedOfficial page does not list a UPS function or switchover time. |
| Weight | 7.8 lb[source]Archived official US page: 'Net Weight 7.8 lb'. Manual: 'Approx. 3.5 kg (7.72 lb)'. | Not publishedOfficial product page text does not state weight (specs shown as images without weight); retailer figures not used. |
| Warranty | 2 years[source]US warranty policy table: 'RIVER 3 | 24' (months). RIVER 3 Plus and RIVER 3 Max get 5 years; the base RIVER 3 does not. | 3 years[source]2-year warranty + 1-year extended warranty, applied automatically only when bought from jackery.com. |

Runtime = usable capacity ÷ average draw, the same formula for both models (no idle draw added to either), after checking continuous output and startup surge. Usable capacity is an independent test's measured figure, or 80% of rated where none exists. See the methodology.
