Last checked on 10 November 2026. The grey text under each name explains what the value means.
| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 256 Wh |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | LFP |
| Cycle lifeHow many full charge and discharge cycles the cells are rated for before they hold less than the stated share of their original capacity. | 80%+ capacity after 3,000 cycles |
| ExpansionExtra battery units that add storage to the same system. | Not stated |
| Output | |
| AC output (continuous)The power it can deliver all the time. Add up the watts of what you want to run at once and stay below this. | 300 W in total, pure sine wave, 230 V |
| AC output (surge)A short burst above the continuous rating, for appliances that draw more power when they start. | 600 W |
| USB-APorts for phones, tablets and small devices. | 5 V 2.4 A (12 W max) |
| USB-CPorts for laptops, phones and tablets. Power delivery up to 100 W can charge most laptops. | Input and output, 5/9/12/15/20 V 3 A, 60 W max |
| Car outletA 12 V socket like the one in a car, for car accessories. | 12.6 V 8 A (100 W max). EcoFlow's page prints '12,6V'. |
| Charging | |
| AC chargingHow fast it charges from a wall socket. Higher means a shorter wait. | 360 W max (220-240 V) |
| Time to charge from the mainsHow long a full charge takes from a wall socket. | 0-80% in 48 minutes; 0-100% in 60 minutes |
| Car chargingCharging from a car's 12 V or 24 V socket while driving. Slow, but useful on the road. | 12 V or 24 V, 8 A, 100 W max; about 3 hours |
| Solar inputHow much solar panel power it accepts. A higher figure fills the battery faster on a sunny day. | 11-30 V, 8 A, 110 W max |
| Solar charging timeHow long a full charge takes from solar panels, in the conditions the maker names. | 2.5 hours with one 110 W portable solar panel (marketing text on the same page says as fast as 3 hours) |
| Backup switchover (EPS)What happens when the grid fails. EPS means it takes over automatically. | Under 30 ms, automatic |
| Housing and warranty | |
| Dimensions (L × W × H)Check the space before you buy, including room around it for airflow and cables. | 245 × 214 × 142 mm |
| WeightMatters for lifting, wall mounting and moving it. | Approximately 3.5 kg |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | Discharging -10 to 45 °C; charging 0 to 45 °C |
| Noise levelFan noise while working. | Not stated |
| WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ. | 5 years |
How long will it run your devices?
Choose how many of each device you want to run at the same time. The wattages are typical figures, so check the label on your own devices.

The estimate assumes 85% of the rated capacity is usable after conversion losses. EcoFlow does not state this figure, so we use a cautious assumption. Real running times vary with temperature, battery age and how each device draws power.
Compatible with
What EcoFlow says this product works with. Anything not listed here is not confirmed.
- Solar panels
- Solar input is 11-30 V, 8 A and 110 W at most, so one 110 W panel is the most it can use.
- Car charging
- 12 V or 24 V car sockets, 8 A, 100 W max.
- App
- The EcoFlow app, over Wi-Fi or Bluetooth.
Rules where you live
A portable power station is not wired into your home, so it is simple to use almost anywhere. Connecting one to your home circuits to power the house is different, and the rules for that vary by country. See our country guides for the rules, incentives and prices where you live.
Strengths and things to check
Strengths
- Light and compact: 3.5 kg
- Charges in about an hour from the mains
- LFP cells rated for 3,000 cycles to 80%+ capacity (EcoFlow's figure)
- 5-year warranty
Worth checking before you buy
- 256 Wh is small: a 100 W load runs for roughly two hours at best
- 300 W output rules out kettles, heaters and most heavy appliances
- Solar input is limited to 110 W
- Not a home battery: do not connect it to your home circuits in a way that lets it feed the house
- The EcoFlow UK page was sold out when we read it

Where this information comes from
We have not tested the RIVER 2. Every figure above comes from EcoFlow's UK product page, last checked on 10 November 2026. A value that the page does not state is shown as not stated. The RIVER 2 is a different product from the RIVER 2 Max and RIVER 2 Pro, which have more capacity and output.
We do not show prices, because they change often and differ between sellers.

Common questions about EcoFlow RIVER 2
What can the RIVER 2 run?
Anything under 300 W, such as phones, laptops, a router, a CPAP machine or a small TV. At 256 Wh, divide by the device's draw for a rough running time, which will be lower in practice because of conversion losses.
Can the RIVER 2 charge from solar panels?
Yes. EcoFlow lists a solar input of 11-30 V, 8 A and 110 W at most, and says one 110 W portable panel can charge it in about 2.5 hours.
Is the RIVER 2 the same as a home battery?
No. It is a small portable power station that you plug devices into. An installed home battery is wired into your electrics by an electrician. See our guide to plug-in and installed home batteries.
