| Spec | EcoFlow RIVER 3 Plus | Jackery Explorer 300 |
|---|---|---|
| Rated capacity | 286 Wh[source]Spec table: 'Capacity 286Wh'. | 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) | 231 Wh[source]SmartZone measured 228 Wh at 100 W and 233 Wh at 600 W AC load, averaging 231 Wh (81% of the rating). That was the EU 230 V version (Schuko outlets); no US-unit AC discharge test found. StorageReview reported 0.43 kWh discharged, which is more than the 286 Wh rating and is not used. | 247 Wh[source]OutdoorGearLab measured 247 Wh delivered (about 84% of the 293 Wh rating). |
| AC continuous output | 600 W[source]Spec table: 'AC Output 3 outlets, 600W total (Surge 1200W, X-Boost 1200W)'. | 300 W[source]'293Wh Capacity, 300W Inverter (500W Surge)'. |
| AC surge output | 1,200 W[source]'Surge 1200W'. X-Boost (also 1200W) runs resistive loads such as heaters by lowering voltage; it is not extra rated output. | 500 W[source] |
| 240 V output | Not publishedOfficial US spec table does not print the AC outlet voltage (it gives AC input as 100~120V and 3 AC outlets, with no 240 V or split-phase output mentioned); the official US online manual did not render. Retailer listings say 120 V, but those are not official. | 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]Spec table: 'Battery Chemistry LiFePO4, 3000 cycles to 80% capacity'. | Lithium-ion[source]Official page says 'lithium-ion battery' without naming the cell chemistry (not LiFePO4). |
| Cycle life | 3,000 cycles to 80% capacity[source] | 800 cycles to 80% capacity[source] |
| AC charging | 380 W[source]'AC Input 100~120V, 10A Max, 50/60Hz, 380W 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 | 220 W[source]'Solar Input 220W, 0-100% in as fast as 1.5 hr'. | Not publishedOfficial page gives only a solar charge time (SolarSaga 100: 0-80% in 3.5 h), not a maximum solar input wattage. |
| Expandable | Yes[source]'Expandable up to 858Wh with a wire-free connection' using one EB300 (286Wh) or EB600 (572Wh) extra battery. | Not publishedOfficial page does not state expandability either way. |
| UPS / EPS switchover | 10 ms[source]Spec table: 'UPS <10 ms'. StorageReview measured a 9 ms transfer. | Not publishedOfficial page does not list a UPS function or switchover time. |
| Weight | 10.4 lb[source]'Net Weight 10.4 lb'. | Not publishedOfficial product page text does not state weight (specs shown as images without weight); retailer figures not used. |
| Warranty | 5 years[source]Warranty policy table lists RIVER 3 Plus at '5 years' (the base RIVER 3 is 24 months). The ecoflow.com/us product page also says '5-year warranty'. | 3 years[source]2-year warranty + 1-year extended warranty, applied automatically only when bought from jackery.com. |
