I’ve been testing two of EcoFlow’s smallest power stations side-by-side: the TRAIL 300 DC and the RIVER 3. Both are ultra-portable, but they approach compact power very differently — the TRAIL 300 DC is a pure DC powerhouse with 288Wh capacity, while the RIVER 3 brings a full AC outlet to the table with 245Wh.
If you’re torn between a lightweight DC-only unit for camping gear or a do-it-all AC station for home backup and road trips, this comparison is for you. I’ll break down exactly where each one shines and where you’ll feel the trade-offs.
🏆 Quick Picks — My Top Recommendations

Let me lay out the exact specs side-by-side so you can see how the TRAIL 300 DC and RIVER 3 really stack up.

The biggest difference here is that the TRAIL 300 DC has no AC outlet at all, while the RIVER 3 gives you a full 300W AC port with X-Boost up to 600W — a dealbreaker for anyone needing wall-plug power.
Individual Product Breakdown
I spent time charging devices, checking weights, and testing the DC output on both of these compact power stations. Here’s how each one performed in real use.

The TRAIL 300 DC is incredibly light at just 2.58 kg — that’s about the weight of a large water bottle — and it packs 288Wh of capacity. I loved the dual 140W USB-C ports that can recharge the unit itself in 85 minutes, which is faster than any other method here. The catch is obvious: no AC outlet means you can’t plug in a laptop charger, a CPAP machine, or any standard wall-plug device. This is a pure DC power station built for 12V coolers, phones, tablets, and camping lights, and it nails that job perfectly.
✅ Pros
- Weighs only 2.58 kg — 48% smaller than the RIVER 3
- 288Wh capacity beats the RIVER 3’s 245Wh
- Dual 140W USB-C ports for fast charging and device power
- LiFePO4 battery with 8-year warranty for long life
❌ Cons
- No AC outlet means you cannot power standard home appliances
- Charging cable is not included in the box
- Only 155 reviews compared to 5,814 for the RIVER 3 — less proven

The RIVER 3 is the more versatile pick by a long shot thanks to its AC outlet and X-Boost technology that pushes 600W peak for appliances like small fridges. I was impressed by the 1-hour full recharge from a wall outlet using X-Stream tech — that’s genuinely fast for a 245Wh station. The built-in UPS feature switches to battery power in under 20ms during an outage, which is a lifesaver for keeping a router or a fish tank pump running. It is heavier at 7.8 lb compared to the TRAIL 300 DC, but the trade-off is getting a proper AC inverter that works at home, in an RV, or at a campsite.
✅ Pros
- Full 300W AC outlet with X-Boost up to 600W for appliances
- 1-hour fast AC recharge from 0% to 100%
- UPS backup switches in under 20ms during power outages
- Over 5,800 reviews and Amazon’s Choice — very popular and trusted
❌ Cons
- 245Wh capacity is 43Wh less than the TRAIL 300 DC
- Heavier at 7.8 lb — not as backpack-friendly as the TRAIL 300 DC
- No 140W USB-C ports; max USB-C output is lower than the TRAIL 300 DC
Which One Should You Buy?
I’ve spent enough time with both of these to know there isn’t one universal winner — it really comes down to whether you need AC power or you’re optimizing for weight and DC-only camping gear. Here’s who each station is built for.
EF ECOFLOW TRAIL 300 DC is right for you if…
- You’re a backpacker or hiker who needs the lightest possible power station at just 2.58 kg and can live without AC outlets
- You power 12V electric coolers on camping trips and want 288Wh of pure DC capacity for longer runtime
- You rely on USB-C PD3.1 devices like modern laptops that can charge at 140W per port
EF ECOFLOW RIVER 3 is right for you if…
- You need a proper AC outlet to run CPAP machines, laptop chargers, or small appliances while camping or during outages
- You want a UPS that switches to battery in under 20ms to keep a router or modem running when the grid goes down
- You value the fastest possible AC recharge — 0% to 100% in just 1 hour with X-Stream technology
❌ Who Should Skip All of These?
If you need to power a full-size refrigerator, a sump pump, or any appliance over 600W running watts, both of these are too small — you’ll want to look at a larger power station with at least 500Wh capacity and a pure sine wave inverter. Also, if you’re planning to run heavy tools like circular saws or compressors on a job site, neither of these will cut it.
For the vast majority of campers, travelers, and home backup users who want a compact power station, I’d pick the RIVER 3 every time — that AC outlet and 1-hour recharge give it way more versatility for only a small trade-off in weight. The TRAIL 300 DC is a specialist tool for ultralight backpackers who truly don’t need AC power.
Frequently Asked Questions
Which is better for camping, the TRAIL 300 DC or the RIVER 3?
For car camping where weight doesn’t matter much, I’d take the RIVER 3 because its AC outlet lets you charge a laptop or run a small fan. But if you’re backpacking or hiking any distance, the TRAIL 300 DC wins easily — it weighs just 2.58 kg compared to the RIVER 3’s 7.8 lb, and its 288Wh capacity actually gives you more DC power for 12V coolers and USB devices.
Can the TRAIL 300 DC charge a laptop?
Yes, but only if your laptop charges over USB-C. The TRAIL 300 DC has dual 140W USB-C PD3.1 ports that can handle most modern laptops, including MacBooks and Dell XPS models. However, if your laptop uses a standard AC barrel plug or an old-style charger, you’re out of luck — there’s no AC outlet on this unit, so you’ll need the RIVER 3 instead.
Is the RIVER 3 worth the extra money over the TRAIL 300 DC?
I think it depends on how you’ll use it. The RIVER 3 gives you a full AC outlet, 1-hour fast charging, and UPS backup that switches in under 20ms — features the TRAIL 300 DC simply can’t match. The TRAIL 300 DC does have a larger 288Wh battery versus 245Wh and is much lighter, so if you only need DC power and value portability above all else, the TRAIL 300 DC is the better value for your specific use case.
Which one has a longer battery life?
The TRAIL 300 DC has a higher capacity at 288Wh compared to the RIVER 3’s 245Wh, so it will run DC devices longer — about 17% more runtime on paper. But the RIVER 3’s X-Boost feature lets it handle appliances up to 600W peak, which the TRAIL 300 DC cannot do at all. For pure DC runtime, the TRAIL 300 DC wins; for versatility with AC devices, the RIVER 3 is the smarter choice.
Can I use solar panels with both of these power stations?
Yes, both support solar charging. The TRAIL 300 DC accepts up to 110W of solar input, and the RIVER 3 can handle 110W as well, recharging in about 2.6 hours under good sun. Neither comes with a solar panel included, so you’ll need to buy one separately — EcoFlow sells 45W and 60W panels that work with both units.
Which one is better for home backup during a power outage?
The RIVER 3 is the clear winner here. Its AC outlet lets you power lamps, a router, a small TV, or a CPAP machine, and the UPS function switches to battery in under 20ms so your devices never shut off. The TRAIL 300 DC has no AC output at all, so it can only keep USB devices and 12V gear running — not very useful for most home backup scenarios.
My Final Verdict
The EF ECOFLOW RIVER 3 is my clear overall winner for most buyers. Its AC outlet, 1-hour fast recharge, and under-20ms UPS backup make it far more versatile than the TRAIL 300 DC, and the 245Wh capacity is still plenty for overnight trips. The TRAIL 300 DC is the better pick only if you’re an ultralight backpacker who needs the 2.58 kg weight and 288Wh DC capacity and truly has no use for an AC outlet.
If you’re on the fence, ask yourself one question: will you ever need to plug something into a standard wall outlet? If the answer is yes, get the RIVER 3. If the answer is no and you want the lightest possible power station with the most DC capacity, the TRAIL 300 DC is your match.
