Anker and EcoFlow are both betting that campers will happily skip the AC outlet. Both companies now sell a 288Wh, 300W station that is DC only: Anker’s SOLIX C300 DC and EcoFlow’s TRAIL 300 DC. On paper they look close to identical. Each uses LiFePO4 cells, has two 140W USB-C ports that charge in both directions, a 120W car socket and a 3-year warranty. The differences are in the details. Anker adds more ports, a built-in light and an app. EcoFlow answers with a lower price, a slightly lighter body and 10W more solar input. I compared both makers’ spec sheets and listings side by side to work out which one fits which camper.

Ports: where Anker pulls ahead
Both stations share the core layout: two 140W USB-C ports that charge in both directions, two 12W USB-A ports and a 120W car socket. Anker adds two more USB-C ports. One is a 100W output, enough for a second laptop. The other is a 15W port for earbuds, headlamps and watches.
That matters most for groups. With the C300 DC, two people can each charge a laptop at full speed (140W and 100W) while phones charge on the smaller ports. On the TRAIL 300 DC, two laptops take both USB-C ports, and phones are left on 12W USB-A.
Anker’s FAQ adds one limit worth knowing. When the 15W USB-C4 port and the USB-A ports are used together, they share 20W. Used alone, USB-C4 gives up to 15W and each USB-A gives up to 12W.
The TRAIL has its own small-device feature. Double-press its button and the USB-A port switches to a low-current mode for three hours. That keeps fitness bands and earbuds from being cut off as “fully charged” before they really are.
Recharge speed
Both use the same approach: plug two 140W USB-C PD chargers into the two two-way ports for 280W of input. Here’s what each maker claims, plus my estimates for slower setups.
| Charging setup | Anker SOLIX C300 DC | EcoFlow TRAIL 300 DC |
|---|---|---|
| Two 140W USB-C chargers | 80% in about 1 hour; Amazon lists 1.5 hours total (Anker) | 0–80% in about 85 min (EcoFlow) |
| One 140W USB-C charger | ~2.3 hours to full (estimate) | ~2.3 hours to full (estimate) |
| One 65W laptop charger | ~5 hours (estimate) | ~5 hours (estimate) |
| Solar | Up to 100W, XT60, 11–28V | Up to 110W |
| Car | Through the solar/car input | Through the solar/car input (cable not included) |
Anker says any USB-C PD charger of 30W or more will work. The first time you power it on, it has to be activated by charging through USB-C2 or USB-C3 with a charger of at least 18W, or with 11–28V solar. Keep that in mind if the unit has been sitting in the box: take a USB-C charger with you on the first trip.
Solar: close, with one compatibility note
EcoFlow’s 110W input is a little higher than Anker’s 100W. In practice the gap is small, since most 100W panels deliver about 70–80W in real sun (estimate). Both stations work fine with 60W to 100W folding panels.
The detail that matters more is Anker’s compatibility note. The C300 DC needs a panel with an XT60 connector in the 11–28V range. Anker says it does not work with its PS30 panel or other 5V/3A USB-C panels, or with the PS200 and PS400. Anker recommends its 60W or 100W panels. With EcoFlow, budget for a separate solar or car cable, because the FAQ says one isn’t in the box. EcoFlow also sells TRAIL 300 DC bundles with 45W, 60W and 110W panels.
The light and the app
The C300 DC’s pop-out light is a bigger deal at camp than it sounds. It lifts above the body and lights a picnic table, so you can leave one lantern at home.
The Anker app lets you check charge level and port use from your phone, which helps if the station sits in a tent or a vehicle. The TRAIL 300 DC has neither a light nor an app. EcoFlow kept it simple: a screen, one button, and nothing to pair.
Size and shape
The C300 DC is a tall, narrow column, 7.87 inches high on a 4.88 x 4.72-inch footprint. Anker sells a shoulder strap separately. The TRAIL 300 DC is shorter and boxier at 6.57 x 4.53 x 6.54 inches, with a woven carry handle, and it’s about half a pound lighter.
The Anker stands up in a cupholder area or a narrow gap between seats. The EcoFlow sits flatter in a crate or a cooler bag.
Runtime: effectively a tie
With identical 288Wh LiFePO4 packs and no inverter losses, runtimes should be nearly the same. My estimates assume about 85–90% of capacity reaches the device:
| Device | Typical draw | Estimated runtime on either station |
|---|---|---|
| Starlink Mini (USB-C PD, 100W cable) | 25–40W average (Starlink spec) | ~6–10 hours |
| 12V compressor cooler | ~20W averaged | ~12–13 hours |
| CPAP on 12V DC, no humidifier | ~30W | ~8 hours |
| Laptop (~60Wh battery) | USB-C | ~4 charges |
| Smartphone (~15Wh) | USB-C or USB-A | ~16 charges |
For Starlink Mini, Starlink requires a 100W, 20V/5A USB PD source when you use its USB-C to barrel jack cable. Both stations’ 140W ports meet that.
Temperature range
Anker lists C300 DC discharging from -4°F to 104°F (-20°C to 40°C) and charging from 32°F to 104°F (0°C to 40°C). That’s typical for LiFePO4. On frosty mornings, keep either station in the vehicle or a sleeping bag until it warms up before charging from solar.
Value
Price is where the TRAIL 300 DC wins clearly. EcoFlow lists it at $159, against Anker’s $349.99 list price, and the C300 DC showed as sold out on Anker’s U.S. store when I checked. Amazon prices for both move often, so check the links above for current pricing.
If the price gap is anywhere near what the maker stores show, the extra ports, light and app have to matter to you to justify the C300 DC.
Who should buy which
Pick the Anker SOLIX C300 DC if…
- You share power with a partner or group and need two laptop-speed USB-C ports plus spares.
- You want a built-in camp light and app monitoring.
- You already own Anker’s 60W or 100W XT60 panels.
Pick the EcoFlow TRAIL 300 DC if…
- You want the most capacity per dollar.
- You prefer something simple, with no app to set up.
- You’d rather carry half a pound less.
For more context, see my EcoFlow TRAIL 300 DC review and my Anker SOLIX C200 DC review, which covers the C300 DC’s smaller 192Wh sibling. If you need wall outlets after all, my Anker SOLIX C300 vs BLUETTI Elite 30 V2 comparison covers the AC versions.
FAQ
Do either of these have AC outlets?
No. Both are DC only, with USB-C, USB-A and a 12V car socket. For a standard plug, look at the regular Anker SOLIX C300 or a small AC station.
Can both run a Starlink Mini?
Yes. Each has 140W USB-C ports that exceed Starlink’s 100W (20V/5A) USB PD requirement. Expect roughly 6–10 hours (estimate).
Which one charges faster from the wall?
Going by the makers’ claims, the Anker C300 DC: 80% in about an hour, compared with about 85 minutes for EcoFlow’s TRAIL 300 DC. Both need two 140W chargers to hit those numbers.
Can I bring either on a plane?
No. At 288Wh, both are above the 160Wh upper limit airlines allow for spare lithium batteries.
Does the C300 DC work with any solar panel?
It needs an 11–28V panel with an XT60 connector. Anker says it isn’t compatible with the PS30 or other 5V/3A USB-C panels, or the PS200 and PS400.
Verdict
These are two well-matched DC stations. Each has the same 288Wh LiFePO4 core and two 140W USB-C ports. The Anker SOLIX C300 DC is the more complete package, with seven outputs, a light and an app. The EcoFlow TRAIL 300 DC delivers most of that for a fraction of the price, in a slightly lighter box. For most solo campers and couples, the TRAIL is the value pick. For group trips and gadget-heavy setups, the C300 DC’s extra ports and light earn their keep.
