Given the current situation, particularly the long-duration blackouts, it’s clear why EcoFlow focuses on portable power stations rather than niche power banks. In fact, I was allotted significantly less time to test the Delta 3 compared to the EcoFlow Trail 200 DC and Trail 300 DC – but I set one condition for the review.

EcoFlow Trail 200 DC and Trail 300 DC Video review
The review of the EcoFlow Delta 3 will be rendered on a laptop powered directly by the EcoFlow Trail units. This approach stems from a recent experience with the ASUS ProArt P16, equipped with an RTX 5090 Mobile, which handled rendering effortlessly both on battery and via Type-C power delivery.
Positioning and price
I’m jumping ahead a bit, but bear with me. For me, 2025 has become the year when my near-obsession with USB-C – especially 100 W PD – finally paid off in ways I never imagined.
Let’s start with pricing. The EcoFlow Trail 200 is priced at around $150, while the Trail 300 DC costs just over $120. There’s also the EcoFlow Trail 300 Plus DC, which is expected to arrive next year.
Packaging and design
In terms of packaging, the boxes include only the power stations themselves and the usual paper materials, from a quick-start guide and warranty to a multilingual specification sheet.
The design raises the question of whether it’s even correct to call them “power banks.” The format is unusual: both models feature a built-in handle for portability. I’ve reviewed similar units before, though not from EcoFlow, and the previous model I tested was essentially discontinued by the time I received it.
If you’re starting to guess how these units work, there are no real surprises. Essentially, each model is just a high-capacity power bank – only scaled up so much that it actually requires a handle for transport.
Specifications
Both models feature the same handle, though only the Trail 300 Plus DC integrates a 140 W USB cable. As a side note, the names Trail 200 and Trail 300 roughly indicate their capacities: the smaller unit has a 192 Wh battery, while the larger models feature 288 Wh. Weight is also relevant, ranging from 1.83 kg for the smaller unit to 2.26 kg for the largest, and all models have an IP30-rated enclosure.
The main difference lies in the ports. On the Trail 200 DC, the unit has four USB ports: two USB-C (100 W and 140 W) and two USB-A (12 W each). The Trail 300 DC features two USB-C ports (140 W), two USB-A ports (120 W), one XT-14 port (up to 100 W), and a 12 V car cigarette lighter socket capable of 110 W. The Trail 300 Plus adds one more USB-C port, and that’s it.
All models share the same LCD screen, which displays battery capacity, charge/discharge time, and input/output power. There are also multiple status indicators, including warnings for overheating, power spikes, or low temperatures – because yes, these power stations can freeze.
In general, any battery can be affected by cold, but the Trail series is positioned as a portable outdoor solution, and it’s easier for travelers to encounter freezing conditions than for someone using it at home.
At this point, those who have been pointing out that for around 9,000 it would be more reasonable to buy a portable power station – arguing that a River 2 can theoretically be found for a similar price – are technically correct. A power station can indeed be purchased at that budget. Alternatively, one could also assemble a setup using five or six high-capacity power banks combined together. Both approaches address the same basic problem of providing backup power, though they differ significantly in practicality, integration, and overall system coherence.
Nuances
Then you run into the nuances. First, a reminder – you don’t always need a full-size outlet, since during blackouts laptops can reliably run on 100W Type-C. As I’ve shown, you can even render video, because modern laptops are valued more for their energy efficiency and memory capacity than raw power. In this context, gigabytes matter more than megahertz.
Next, even the River 3 Plus, a modern model, has a lower capacity than the Trail 300 DC: 245 Wh versus 288 Wh. How is that possible? It’s quite simple – if there’s no need for a transformer inside to convert 12 V from the battery to 220–230 V for an outlet, the device can be made more compact. It also generates less heat, so there’s no need for a separate active cooling system.
І
…there is no energy loss as heat. In my review of the be quiet! Dark Power 14 1200W, I noted that the lower the heat loss to the surrounding environment, the more reliable the components operate. The Trail series is fully passive, after all. And this is despite the fact that the Trail 300 DC can deliver up to 300 W simultaneously.
However, this also means that the Trail units do not support Pass-Through or UPS functionality. To be precise, the battery inside the Trail will charge and discharge if it remains constantly connected to the mains. In other words, it can supply power while simultaneously receiving it via USB.
Since the batteries here are not Li-Ion but LiFePO₄, you won’t experience degradation that reduces the maximum capacity. At the same time, devices connected via USB to the Trail 300 – such as lights – won’t notice any change if the mains power goes out. For reference, the Trail comes with a three-year warranty, and the endurance of lithium-iron-phosphate batteries exceeds 2,000 cycles, which translates to over five years of daily recharging.
Summary
It’s encouraging to see the return of the large-format power bank concept, and EcoFlow’s implementation – specifically the EcoFlow Trail 200 DC and EcoFlow Trail 300 DC – was impressive. The aspects I expected, such as reliability, versatility, and compactness, were all present. What I didn’t anticipate was the overall power output, nor that the Trail 300 DC would be cheaper yet have a higher capacity than the EcoFlow River 3. These findings are surprising, in a positive way, and for that reason, I consider them worth recommending.
