EcoFlow’s TRAIL 300 DC drops the AC inverter altogether. What’s left is a 288Wh LiFePO4 battery with 300W of pure DC output in a 5.69 lb box about the size of a lunchbox. EcoFlow’s spec table lists two 140W USB-C ports that work as inputs and outputs, two 12W USB-A ports, a 12V car outlet rated at 120W and a 110W solar or car input. EcoFlow sells it for $159 (list price $250) with a 3-year warranty. EcoFlow says DC output covers about 90% of outdoor gear, which is the whole pitch. This review covers what it can run, how fast it recharges and where it fits.

Why a DC-only power station makes sense
Most of what you take camping runs on DC anyway: phones, laptops, cameras, headlamps, drones, speakers, 12V coolers and Starlink Mini. A normal power station converts its battery to 120V AC through an inverter, and then each device’s charger converts it back to DC. That double conversion loses energy, and the inverter also draws power just by being on. Dropping it is how EcoFlow fits 288Wh into a 5.69 lb case. EcoFlow says it’s 48% smaller and 27% lighter than its RIVER 3 in the same capacity range.
The trade-off is simple: no wall outlets. If you need to run a hair dryer, a blender or anything with a standard plug, this isn’t the right tool. For everything with USB-C or a 12V plug, it is.
What it can run (estimates)
These assume about 90% of the 288Wh (about 260Wh) reaches the device, since DC conversion loses less than an inverter does. They’re estimates, not test results.
| Device | Port | Typical draw | Estimated runtime or charges |
|---|---|---|---|
| Smartphone (about 15Wh battery) | USB-C or USB-A | — | ~17 full charges |
| Laptop (about 60Wh battery) | USB-C 140W | — | ~4 full charges |
| Starlink Mini | USB-C (100W PD) with barrel cable | 25–40W (Starlink’s average) | ~6.5–10 hours |
| 12V compressor cooler | 12V car outlet | ~20W averaged over a day | ~13 hours |
| CPAP on 12V DC, no humidifier | 12V car outlet | ~30W | ~8.5 hours, about one night |
| LED string lights | USB-A | ~5W | ~50 hours |
| Drone batteries (about 40Wh each) | USB-C | — | ~6 batteries |
For Starlink Mini, use a USB-C to barrel-jack cable rated for 100W PD. I covered one in my STARGEAR retractable USB-C cable review, and my BLUETTI Elite 30 V2 Starlink Mini test shows how a small station and panel handle the dish. For 12V coolers, start-up current is the thing to watch. The 120W car outlet handles most compressor coolers, but check your cooler’s rated draw first.
A weekend power budget
Here’s a realistic two-day car-camping budget for two people. The figures are my estimates.
| Item | Use per day | Energy per day (estimate) |
|---|---|---|
| 2 smartphones | 1 full charge each | ~35Wh |
| Camera batteries | 2 charges | ~25Wh |
| LED lantern and string lights | 5 hours | ~25Wh |
| Bluetooth speaker | 1 charge | ~10Wh |
| Laptop | 1 charge | ~65Wh |
| Total | ~160Wh/day |
That’s about 1.6 days from a full charge. Add a 60W panel for a few hours each afternoon and the whole weekend is covered. Adding a 12V cooler changes the math a lot. A cooler alone can use 300–500Wh in a summer day (estimate), more than the whole battery. For that, look at a bigger station or pair the cooler with a larger panel.
TRAIL 300 DC vs a large power bank
Most large power banks stay under 100Wh so they can fly without airline approval. The TRAIL 300 DC holds nearly three times that. More importantly for camping, it adds a 120W 12V car outlet and a 110W solar input, which ordinary power banks don’t have. Since it’s LiFePO4, it also tolerates frequent deep cycling better than the lithium-ion cells inside most power banks. On the other hand, a power bank fits in a pocket and goes on planes. Many people will want both: a power bank for the trail and the TRAIL 300 DC at camp.
Recharging it
There are three ways to charge it. Use both USB-C ports together for the fastest top-up.
| Method | Max input | Approx. time (estimate unless noted) |
|---|---|---|
| Dual USB-C (2 × 140W wall chargers) | 280W | 0–80% in about 85 min (EcoFlow figure) |
| Single USB-C (140W) | 140W | ~2.3 hours to full |
| Single USB-C (65W laptop charger) | 65W | ~5 hours |
| Solar panel | 110W | ~3–4 hours of good sun with a 110W+ panel |
| Car socket | 110W (about 100W from most 12V sockets) | ~3 hours of driving |
EcoFlow’s FAQ notes that the box doesn’t include a car charging cable or a solar cable, so budget for those if you plan to use them. EcoFlow sells TRAIL 300 DC bundles with 45W, 60W and 110W solar panels. With a 45W panel, expect roughly 150–200Wh on a sunny day (estimate). That’s enough to keep phones, lights and a Starlink Mini going for a few hours, but not a cooler running all day.
TRAIL 300 DC vs TRAIL 200 DC vs TRAIL Plus 300 DC
| Spec | TRAIL 200 DC | TRAIL 300 DC | TRAIL Plus 300 DC |
|---|---|---|---|
| Capacity | 192Wh LFP | 288Wh LFP | 288Wh NCM |
| Max output | 220W | 300W | 300W |
| USB-C | 1 × 140W + 1 × 100W | 2 × 140W | 3 × 140W |
| 12V car outlet | No | 120W | 120W |
| Solar / car input | No | 110W | 110W |
| App | No | No | Wi-Fi / Bluetooth |
| Built-in light | No | No | Camping light |
| Weight | 4.03 lb | 5.69 lb | 4.98 lb |
| EcoFlow price (Oct 2026) | $119 | $159 | $199 |
The TRAIL 300 DC is the sweet spot. It’s the cheapest model with a 12V car outlet and a solar input, both of which matter for coolers and multi-day trips. The TRAIL 200 DC is basically a big USB-C power bank. The TRAIL Plus 300 DC adds a third USB-C port, an app and a camping light, but it uses NCM cells instead of LiFePO4.
Handy features
- Low-current mode. Small devices like earbuds and fitness trackers can draw so little that a normal port switches off. Double-click the multi-function button and the USB-A port enters low-current mode for 3 hours, per EcoFlow’s FAQ.
- Pass-through USB-C. Both 140W ports work as inputs or outputs, so one cable type covers charging the TRAIL and running your laptop.
- Built for knocks. EcoFlow describes five layers of drop protection and fire-resistant construction. EcoFlow also lists a waterproof carrying case for the TRAIL series, sold separately.
Storage and travel notes
EcoFlow recommends storing it in a dry, cool place, ideally at 0–30°C (32–86°F). During long storage, EcoFlow suggests charging it fully and then discharging it to 60% every three months. It can’t go on a plane: at 288Wh, it’s over the 160Wh airline limit, as EcoFlow’s own FAQ notes. For flying, a sub-100Wh power bank is the way to go.
Who it’s for
- Car campers and overlanders who run a 12V cooler, lights and phones.
- Photographers and drone pilots who need many battery top-ups away from the car.
- Remote workers running a laptop and Starlink Mini from a picnic table.
- Home emergency kits for keeping phones, a router (via a 12V adapter) and lights going in a short outage.
If you need AC outlets, look at a small power station with an inverter instead. My EnginStar 300W review covers one that ran Starlink, a MacBook and a TV.
