Start with what the listings actually sell, because anker solix c300 vs ecoflow river 3 plus is not, in these listings, a match between power stations. The Anker side is an amiumuca travel bag made to carry the SOLIX C300, bag only; the EcoFlow side is the River 3 Plus portable power station itself. So the honest comparison is accessory against station: what the bag does for the C300 you already own, and what the River 3 Plus states as a station. Stated function, capacity and output figures, charging, outlets, protections and warranty were compared, using only what each listing publishes.

Specifications are manufacturer rated as listed, collected 22 October 2026. One listing carries a station; the other is a station.
What each listing actually sells
The amiumuca listing is a travel bag designed for the Anker SOLIX C300: 1680D Oxford cloth outside, aluminum foil lining inside, 8mm pearl cotton in the middle for shock absorption, a front zippered pocket for screen access, side pockets for cables, and an adjustable shoulder strap, at 11.8 by 10.2 by 5.5 inches and 0.48 kg. Its bullets describe the station it fits as an outdoor 288Wh LiFePO4 battery with 300W output and 600W surge, and note the station can be used inside the bag without removing it. The EF ECOFLOW listing is the River 3 Plus station itself: 286Wh, a steady 600W with surges to 1200W on X-Boost, 7 outlets, and a 5-year service stated in the box list. Do not read the bag’s station figures as the bag’s own specs; they describe the C300 the bag was cut to fit.
Power and capacity, where stated
On the figures each listing gives for its station, the two sides sit close on capacity and apart on output. The bag listing describes the C300 as 288Wh with 300W output and 600W surge. The River 3 Plus listing states 286Wh with a steady 600W and 1200W surge on X-Boost, plus 7 outlets: 3 UPS-supported AC, 2 USB-A, a high-speed USB-C and a car charger output. The River 3 Plus adds an expandable path the bag side cannot match: compatible EB300 (286Wh) or EB600 (572Wh) extra batteries stack the station up to 858Wh, with Pogo Pin wireless connection and a 140W USB-C port on the extra battery. Do not call a side better on capacity unless both listings state the spec the same way; on output, the River 3 Plus listing states the higher pair, 600W steady against the C300’s listed 300W.
Charging, outlets and extras
Charging is fully specified on the station side and absent on the bag side, as it should be. The River 3 Plus lists AC charging from 0 to 100 percent in 1 hour with X-Stream, solar recharge in 1.5 hours with a 220W solar input, a 10 ms UPS switchover for home office and gaming setups, and twice the runtime for appliances under 100W on X-GaNPower. It runs at a quiet 30 dB, measures 9.2 by 9.1 by 5.8 inches, and connects over Bluetooth and Wi-Fi with an app for speed control, timed charging and low-battery notifications. The bag’s extras are about carrying, not power: a front pocket positioned for the C300’s screen, side pockets for data cables, a top opening for the station’s own handle, and a detachable shoulder strap.

What the listings leave unclear
Each listing has at least one rough edge. The River 3 Plus title says 760W while its bullets state a steady 600W with 1200W surge on X-Boost; trust the bullets’ pair, not the title figure. Its bullets state 10.4 lbs while its spec table states 3.5 kg; trust the bullets here as well. The amiumuca title promises two pockets while its bullets describe a front zippered pocket plus pockets on both sides, so the pocket count is unclear. The bag listing states water resistance for the zipper and shell without an IP code, while the River 3 Plus states IP54 battery protection, so a water-protection comparison between the two cannot be made on equal terms.

How we scored them
The Solar Score weighs performance, build, value, safety and warranty, and here it measures how completely each listing delivers its own job. The River 3 Plus states IP54 battery protection, a fire-retardant shell, UPS switchover and a 5-year service term, so it scores across safety and warranty. The bag states 1680D Oxford cloth, 8mm shock-absorbing pearl cotton and water resistance, but no certification and no warranty term, so its safety and warranty lines score lower. The ranking is not a verdict that a station beats a bag; it measures stated completeness within two different jobs.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| EF ECOFLOW River 3 Plus | 9.7 | 32 | 21 | 20 | 8 | 3 |
| amiumuca travel bag for SOLIX C300 | 9.4 | 23 | 19 | 18 | 5 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
Anker Solix C300 vs EcoFlow River 3 Plus: which should you choose?

Choose the River 3 Plus if you are shopping for the station itself: 286Wh, 600W steady with 1200W surge, 7 outlets, 1 hour AC charging, 10 ms UPS and a 5-year service term, expandable to 858Wh.
