Overview

The RIVER 3 is EcoFlow's entry unit: a 245 Wh LFP pack (3,000 cycles to 80%+ SoH) feeding two AC outlets at 300 W continuous, with X-Boost letting simple resistive loads draw up to 600 W. Wall charging accepts 320 W for an official 0–100% in 60 minutes, and the solar input takes 110 W (11–30 V). The page markets 'UPS | <20 ms', but EcoFlow's own manual classifies the base RIVER 3's sub-20 ms switchover as EPS and reserves 'UPS' for the separate 'RIVER 3 (10 ms UPS)' variant — so this record classifies it as marketed-UPS. At 3.5 kg with a flat, stackable shape, it is squarely a device-charging and light-AC unit.

Variant note: Manual covers three variants: RIVER 3 / RIVER 3 (10 ms UPS) (model EFR705, 245 Wh) and RIVER 3 (230) (model EF-RV-H01-1, 230 Wh). This record is the standard US RIVER 3 (245 Wh). RIVER 3 Plus / Max / Max Plus are separate larger models.

Data note: Researched as the substitution for RIVER 2, which shows 'Sold out' on us.ecoflow.com (page still live) while the RIVER 3 line is the current in-stock entry lineup. X-Boost 600 W is a boost mode listed separately from surge in the official spec row; never counted as continuous. UPS/EPS labeling conflict is intra-official: page says 'UPS | <20 ms', manual says base model supports 'emergency power supply (EPS) with a transfer time within 20ms' and reserves UPS for the 10 ms UPS variant — classified ups_eps_marketing per policy. Dimensions are W×D×H in the source (255 × 212 × 113 mm) and stored in source order. Warranty (24 months) comes from the official warranty-policy table; no duration is stated on the product page itself. MPPT not mentioned in official sources — null.

Use cases

  • Day trips and picnics: 3.5 kg, flat stackable form
  • Desk companion for router/laptop backup via <20 ms switchover
  • Phone/drone/camera charging hub with 100 W USB-C
  • Light AC loads under 300 W (up to 600 W resistive via X-Boost)

Strengths and weaknesses

Strengths

  • Official 0–100% wall recharge in 60 minutes
  • 3,000-cycle LFP at an entry price class where NMC lingers
  • 3.5 kg — lightest unit in this index
  • 100 W USB-C port charges most laptops

Weaknesses

  • 245 Wh capacity limits it to devices and brief light-AC use
  • Marketed 'UPS' is EPS per EcoFlow's own manual; true 10 ms UPS is a separate variant
  • Solar capped at 110 W
  • 2-year warranty — far below the 5 years EcoFlow gives the RIVER 3 Plus/Max
  • No expansion battery support on the base model
