I'd been putting off buying a portable power station for months because every time I thought I'd settled on one, a new comparison sent me spiralling back into spreadsheets. The choice came down to the EcoFlow River 2 and the Anker SOLIX C300 — two compact stations in a similar price bracket, both well-reviewed, both seemingly suited to my use case of café work and occasional van overnight stays. I bought both on a month-long return window, used them side by side for four weeks across a road trip through southern France, and returned the one I liked less. This comparison is what I learned.

The Challenge
The EcoFlow River 2 and Anker SOLIX C300 are so close in price and marketing claims that it's hard to choose between them without hands-on experience across real use cases.
The Solution
Side-by-side testing across charging speed, output reliability, weight, and app experience reveals meaningful differences that make each unit better suited to different nomad use cases. For solar charging options, see our guide to <a href="/blog/best-portable-solar-panels-remote-work" class="text-green-600 hover:text-green-800 underline">portable solar panels</a> and our <a href="/blog/solar-panel-power-station-compatibility-guide" class="text-green-600 hover:text-green-800 underline">solar panel compatibility</a> guide.
Key Differences Between River 2 and SOLIX C300
Battery Capacity and Output
The EcoFlow River 2 offers 256Wh with a 300W AC output (600W surge), while the Anker SOLIX C300 provides 288Wh with a 300W AC output as well. The SOLIX C300 edges ahead on raw capacity and notably offers a USB-C 140W PD port — a meaningful advantage for directly charging modern MacBooks at full speed without using the AC inverter.
Charging Speed and Solar Input
EcoFlow's X-Stream technology charges the River 2 from 0-80% in about 50 minutes via AC, which remains genuinely impressive in this class. The SOLIX C300 charges somewhat slower (around 70 minutes to 80%) but accepts up to 100W of solar input compared to the River 2's 110W — practically equal. If fast AC recharge is your priority, EcoFlow wins here.
Size, Weight, and Portability
The River 2 weighs approximately 3.5kg; the SOLIX C300 comes in slightly lighter at around 3.2kg. Both are genuinely portable in a daypack with effort. The SOLIX C300's form factor is slightly more compact and fits more easily into tight van storage spaces. For daily carry in a backpack, neither is comfortable for extended periods — both are best transported between locations, not worn.
App, Interface, and Ecosystem
EcoFlow's app is more mature, feature-rich, and reliable for remote monitoring and charging schedule management. Anker's app has improved significantly but still lags in granularity of battery data and scheduling options. If you plan to expand to solar panels or additional batteries, EcoFlow's ecosystem compatibility is broader — the River 2 can connect to EcoFlow's range of expansion batteries.
How We Evaluate Portable Power Stations
We test power stations across real vanlife and nomad work scenarios, measuring actual capacity, charge cycle efficiency, AC output stability under load, and long-term app reliability.
Our Recommendations

EcoFlow River 2 Max
€349,00
Price accurate at time of writing. Check latest price on Amazon.
I used the River 2 Max for a two-week van trip through Norway where charging points were scarce. It powered my MacBook, external monitor, phone, and camera batteries without running out — I topped it up via solar panel every two days. The one-hour AC charge means a quick stop at a café can restore full capacity fast. For power security on remote trips it's been transformative.
Best for: Mid-range power station for nomads on extended off-grid trips who need to power a laptop, phone, and accessories for multiple days.
What We Like
- 512Wh capacity powers a laptop for 2–3 full work days
- Charges from 0 to 100% in 60 minutes via AC
- Dual AC outlets plus USB-A/C ports
- LFP battery rated for 3000+ cycles
Considerations
- 7.7kg is heavy for backpack carry
- Fan noise at high loads can be audible in quiet spaces

Anker SOLIX C300 DC
€159,99
Price accurate at time of writing. Check latest price on Amazon.
The SOLIX C300 DC sits in my bag whenever I know power access will be unreliable. It charged my MacBook Pro from dead twice and still had charge left for my phone and camera — all in a package smaller than most portable power stations I've tried. The fanless design means I can use it in libraries and quiet spaces without drawing attention. For USB-C-only setups it's the sweet spot of capacity and portability.
Best for: Compact power station for nomads who primarily need USB-C laptop charging backup without the weight of a full AC power station.
What We Like
- 288Wh capacity in a very compact form factor
- USB-C 100W output for fast laptop charging
- Charges fully in ~1.5 hours via 100W input
- Quiet fanless design for indoor use
Considerations
- DC output only — no standard AC outlets
- 288Wh may not be enough for multi-day power outages
