A popular portable power solution just dropped to an interesting price. The EcoFlow Trail 300 DC Power Bank Station is currently on sale for $147, a $102 cut from its usual pricing of $249 and a discount that makes one of our more favored DC-first battery packs far easier to recommend to campers, road trippers, and field pros.
Why This EcoFlow Trail 300 Deal Is So Spiffy
Discounts on DC-centric fast USB-C power stations are not unusual, but this one underprices the bulk of the competition while maintaining all the important specs that matter.

The Trail 300 packs a 288Wh battery and maxes out with a 300W DC port, in addition to dual 140W USB-C and dual 12W USB-A outputs—power output that’s enough to power laptops, cameras, drones, routers, small appliances, and more without having to haul around a full-size AC inverter setup.
It also comes in for less than a major competitor, Anker’s comparably sized Solix C300 DC, which runs for around $162.49 at the moment. The Anker model has an integrated light, the main trade-off. If you can live without that, the EcoFlow deal is a money-saver and matches up closely on the core power profile.
Key Specs and How It Performs in the Real World
Capacity: 288Wh. For reference, that’s about 16 charges of a normal 5,000mAh smartphone in practice—let’s be real here for a second since a modern phone battery is somewhere around 18–20Wh. It’s also practically enough for around 4 hours of USB-C laptop time at 60W (given some conversion overhead), anywhere from 5–6 hours for a 45W CPAP without humidifier, or a day-plus of use for an Internet-enabled Wi-Fi router during an outage.
Power up: Each of the two ports on this USB-IF power bank outputs up to 140W (according to the USB-PD 3.1 EPR profile), so you can top off a power-hungry laptop without compromising performance and charge multiple devices while staying productive—a perfect option for charging up your 16-inch notebook.
There are also two extra USB-A ports for your legacy gear.
300W DC port: If used with devices that accept 12V barrel or vehicle power, you won’t have to worry about wasted AC inversion. Many small-inverter packages are rated 90–95 percent efficient by NREL, so DC reduces power loss and extends endurance.

Solar and Recharging Flexibility for Off-Grid Use
The unit can take up to 110W of solar input, so you can refuel off-grid. In open sky, you can expect 3–5 hours of peak-sun charging on a hot day to reach from nothing to full (assuming good panel quality and safe conditions). You can also refill from a wall outlet or car port, meaning you have several ways to top off between campsite and commute.
Build Quality and Portability for Outdoor Use
Built for the outdoors, the five-layer construction is designed to be able to take a bump or drop, according to EcoFlow. At 5.96 lb, it’s lighter than most AC-inverter stations with similar capacity, and its compact footprint makes it easy to backpack to a picnic spot or tuck into a vehicle recovery kit.
How It Compares with Anker’s Solix C300 DC Rival
When you compare it to the Anker Solix C300 DC—heartily recommended, just like the EcoFlow—you pay less and get about the same capacity and port selection. The Anker also has an integrated light, which some overlanders appreciate when setting up camp. If you don’t care about illumination, the EcoFlow’s lower price and equivalent power make it an easy choice.
Buying Advice and Caveats Before You Hit the Road
Air travel: This battery is bigger than what you can take onto most airlines (288Wh). Many airlines operate with restrictions at 100Wh (or up to 160Wh if prior approval is granted). At 288Wh, it would be banned from either the cabin or checked baggage. Plan to drive and pack it in your car, van, or RV.
DC-only design: No AC outlet, and no built-in light. If you need or want to run traditional (read: AC) appliances, look at an inverter-equipped unit but consider the increased size, weight, and conversion losses. If your kit is USB-C/USB-A and DC-ready, the Trail 300’s efficiency yields longer runtimes from those same watt-hours.
Bottom line: At $147, the EcoFlow Trail 300 is a clear sweet spot for portable, efficient power with high-tech USB-C output and solar-ready charging. Campers, weekend warriors, and on-the-go creatives who live on DC and USB-C won’t find a better deal for this price, for any length of time.
