Anker C300 vs EcoFlow RIVER 2 Pro: which power station is the smarter buy?

Display

Neither product is really trying to win on a flashy screen, but the user interface still matters. EcoFlow units are generally known for a more polished app ecosystem and clearer battery management, while Anker’s SOLIX range tends to keep things simpler and more compact. On pure usability, EcoFlow wins because the larger-capacity system benefits more from better monitoring, especially when you are tracking charging speed, solar input, and AC output over longer sessions. For a smaller 288Wh unit, Anker’s simpler approach is acceptable, but EcoFlow gives you more confidence when managing a much bigger battery.

Winner: EcoFlow RIVER 2 Pro

Performance

This is the biggest dividing line. The Anker SOLIX C300 offers 300W continuous output and 600W surge, which is fine for phones, tablets, cameras, LED lighting, routers, and some small laptops. The EcoFlow RIVER 2 Pro is in a different class with 768Wh capacity and AC output rated for far more demanding use, including 4 x 800W AC outlets with X-Boost up to 1600W for certain devices. That means the EcoFlow can run more appliances for longer, and it can cope with higher-drain equipment that would simply overwhelm the Anker.

For camping, emergency power, and occasional home backup, EcoFlow is the clear performance winner. The Anker is still useful, but it is best viewed as a compact power bank on steroids rather than a true multi-device power station.

Build quality and design

Anker has a strong reputation for tidy industrial design, solid plastics, and reliable everyday electronics, and the C300 fits that mould. It is easier to carry, less intimidating in size, and better suited to people who want a grab-and-go unit for a flat, balcony, or tent. EcoFlow’s RIVER 2 Pro is also well built, but it is larger and heavier, which is the trade-off for the extra battery capacity and output headroom.

If portability and minimal footprint matter most, Anker wins on design practicality. If you want a more substantial, capable unit that still remains portable, EcoFlow’s build is better aligned to the job, even if it is less convenient to move around.

Battery life

Battery life is where the numbers make the decision easy. The Anker has 288Wh of LiFePO4 storage, which is enough for short bursts of use, but it will drain quickly under anything beyond modest loads. The EcoFlow’s 768Wh battery gives you well over double the energy reserve, so it can keep devices running much longer and support more realistic emergency use. Both use LiFePO4 chemistry, which is a major plus because it is safer and generally longer-lasting than NMC batteries, with better cycle life for frequent charging.

Because capacity is the main driver of runtime, EcoFlow wins decisively. If you want a unit that can bridge a power cut, run a camping fridge for longer, or support multiple devices through a weekend, the Anker is simply too small.

Winner: EcoFlow RIVER 2 Pro

Price and value for money

Here the Anker makes its case strongly. At £222.90, it is £276.10 cheaper than the EcoFlow, and it still gives you LiFePO4 chemistry, solar charging support, and fast two-way charging at up to 140W. For light users, that is excellent value. The EcoFlow at £499 is expensive, but you are paying for a much larger battery, more output, and a more capable all-round system.

Value depends on use case. If you only need backup for small electronics, the Anker is the better buy because you are not overpaying for capacity you won’t use. If you need genuine versatility, the EcoFlow justifies its higher price more convincingly than most premium portable stations.

Winner: Tie, leaning Anker for budget buyers and EcoFlow for heavy users

Game library/features

These are not gaming products, so the relevant “features” are charging inputs, portability, app support, and emergency usefulness. The Anker’s standout feature is its 140W two-way fast charging, which makes it convenient to top up quickly and keep the unit ready. The EcoFlow counters with 70-minute fast charging, much larger solar-generator potential, and a broader feature set for outdoor, RV, and home use. If you care about solar compatibility and real-world versatility, EcoFlow has the richer feature set.

Overall user experience

For everyday simplicity, the Anker is the easier product to live with. It is cheaper, lighter, and more suited to people who want backup power without complexity. For most UK renters, that means charging phones, keeping Wi-Fi alive briefly, powering lights, and handling short outages. The EcoFlow is better if you want a power station that can genuinely replace mains power for longer periods or support more demanding kit without constant rationing.

Overall, the EcoFlow RIVER 2 Pro is the better product in terms of capability, runtime, and long-term usefulness. The Anker SOLIX C300 is the better purchase only if your needs are modest and budget is the priority. If you want the definitive answer: buy the EcoFlow if you want a real power station; buy the Anker if you want a compact, affordable backup box for light use.
