Specs
| Rated capacity | 286 Wh[source]Spec table: 'Capacity 286Wh'. |
|---|---|
| Usable capacity (AC) | 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. |
| Battery chemistry | LiFePO4[source]Spec table: 'Battery Chemistry LiFePO4, 3000 cycles to 80% capacity'. |
| AC continuous output | 600 W[source]Spec table: 'AC Output 3 outlets, 600W total (Surge 1200W, X-Boost 1200W)'. |
| 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. |
| AC outlets | 3[source]'3 outlets'. The '7 outlets' headline on ecoflow.com counts USB and car ports too. |
| UPS / EPS switchover | 10 ms[source]Spec table: 'UPS <10 ms'. StorageReview measured a 9 ms transfer. |
| Expandable | Yes[source]'Expandable up to 858Wh with a wire-free connection' using one EB300 (286Wh) or EB600 (572Wh) extra battery. |
| Max expanded capacity | 858 Wh[source]286 Wh unit + EB600 (572 Wh). |
| AC charging | 380 W[source]'AC Input 100~120V, 10A Max, 50/60Hz, 380W 0-100% in 60 min'. |
| Max solar input | 220 W[source]'Solar Input 220W, 0-100% in as fast as 1.5 hr'. |
| Cycle life | 3,000 cycles to 80% capacity[source] |
| Weight | 10.4 lb[source]'Net Weight 10.4 lb'. |
| 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'. |
| Idle draw | Not publishedNo independent test found. SmartZone, StorageReview and The Solar Lab report no idle draw figure. |
| List price | $299[source]Regular price $299.00, compare-at also $299.00 (no sale) seen 2026-10-18. |
