Choosing the right portable power station can feel overwhelming. You're faced with two excellent options: the Anker SOLIX C300X DC and the EcoFlow RIVER 2. They look similar, but they are designed for fundamentally different users. At TeqClub, we want to cut through the confusion. This guide is a direct comparison to help you understand which of these powerhouses is the perfect match for your specific adventure, ensuring you invest in the right gear for your needs.
1. The Core Difference: Specialist vs. Generalist
The most important thing to understand is the core design philosophy behind each unit. The Anker SOLIX C300X DC is a specialist. As the "DC" in its name implies, it is built exclusively to power devices that run on Direct Current, like 12V car fridges, fans, and USB gadgets. It has no internal AC inverter, which is a deliberate choice to maximize efficiency for off-grid setups. In contrast, the EcoFlow RIVER 2 is a versatile generalist. It includes an AC outlet, allowing you to plug in standard wall chargers for laptops, drone batteries, and cameras. This flexibility makes it a jack-of-all-trades, but that versatility comes with a trade-off in certain scenarios.
2. Side-by-Side Specs: A Head-to-Head Look
Let's break down the technical specifications. While numbers don't tell the whole story, they provide a great starting point for comparison. Both units use modern, long-lasting LFP (LiFePO4) battery chemistry, ensuring thousands of charge cycles.

| Output Ports | 1x Car Socket (12V) 2x DC5521 2x USB-C 2x USB-A | 1x AC Outlet 1x Car Socket (12V) 2x DC5521 1x USB-C 2x USB-A |
| Weight | 2.9 kg (6.4 lbs) | 3.5 kg (7.7 lbs) |
| Solar Input | 100W Max | 110W Max |
| Battery Chemistry | LFP (LiFePO4) | LFP (LiFePO4) |
3. Real-World Efficiency: The DC Advantage
This is where the Anker SOLIX C300X DC truly shines for a specific user. Let's say you're running a 12V portable fridge on a camping trip. With the C300X DC, power flows directly from its DC battery to your DC fridge. The path is short and highly efficient. Now, imagine you need to charge your laptop with the EcoFlow RIVER 2. The power station must convert its battery's DC power to AC power for the outlet. Then, your laptop's power brick converts that AC power back to DC to charge its battery. Each conversion step wastes energy as heat. For DC-native devices, the C300X DC will provide significantly longer runtimes from a similar battery capacity because it skips this wasteful conversion process entirely. This is a game-changer for overlanders and van-lifers who rely on 12V gear. ⚡
4. When to Choose the Anker SOLIX C300X DC
The choice becomes clear when you look at your primary devices. If you primarily run 12V DC equipment, choose the Anker SOLIX C300X DC. It's the undisputed champion of efficiency for this use case. It’s lighter, offers a bit more capacity, and will keep your essential gear like portable coolers, water pumps, and camp lights running for much longer. It's the purpose-built tool for the dedicated off-grid adventurer who has already invested in a DC ecosystem.
5. When the EcoFlow RIVER 2 Makes More Sense
On the other hand, the EcoFlow RIVER 2 is the go-to for maximum flexibility. If you need the versatility of AC power for devices like your laptop, camera battery charger, or a small fan with a standard plug, choose the EcoFlow RIVER 2. It's the perfect companion for weekend camping trips, backyard parties, or as a small emergency backup at home where you might need to power a variety of gadgets. What you lose in niche DC efficiency, you gain in the ability to power almost any small electronic device you own.
Your Perfect Power Companion Awaits
Ultimately, there is no "winner" here—only the right tool for the job. The Anker SOLIX C300X DC is the highly efficient specialist for DC-heavy setups, while the EcoFlow RIVER 2 is the adaptable generalist for everyday power needs. By evaluating the devices you rely on most, you can confidently make the right choice. Your ideal portable power solution is the one that seamlessly integrates with your lifestyle.
