Our take
What the TRAIL 300 DC is good at, and what to watch for
KiloHour take Pick it if you want light DC power for phones, laptops, lights and 12V gear at camp, but it has no AC outlets, no app and cannot go on a plane.
The TRAIL 300 DC is a 288Wh LiFePO4 battery with no AC inverter, so it runs only DC gear: USB-C devices, USB-A lights and 12V car-socket accessories. EcoFlow lists 300W of total DC output, with any single port limited to 140W, and up to five devices charging at once.
The port list is simple. Two USB-C ports handle 140W each in either direction, there are two 12W USB-A ports, and the 12V car outlet is rated at 120W max. It recharges over USB-C, or through a separate 110W input that takes either solar or car charging. Cables for car and solar charging are bought separately.
At 2.58 kg (5.69 lb), it is light enough to carry by its woven handle. EcoFlow's TRAIL page also shows two siblings. The TRAIL 200 DC drops to 192Wh and 220W and has neither the car outlet nor the solar input. The TRAIL Plus 300 DC keeps 288Wh but uses NCM cells and adds a third USB-C port, app control and a built-in light.
The trade-offs come from the design. Without an inverter it cannot run anything with a wall plug, and this model has no app connection. It is rated IP30, with a waterproof carrying case sold separately, and has a three-year warranty. At 288Wh it is over the 160Wh airline limit, so EcoFlow's FAQ says it cannot be taken on a plane.

FAQ
TRAIL 300 DC questions
Answers use the same published specs and labelled assumptions as the calculator.
Does the TRAIL 300 DC have an AC outlet?
No. It has no inverter, so it only powers 12 V and USB devices, up to 140 W from one USB-C port. A CPAP needs its maker's DC adapter to run from it.
How long will the TRAIL 300 DC last?
288 Wh stored, about 259 Wh of it usable at the typical estimate.
What is the TRAIL 300 DC solar input?
Its limit is 110 W, below a 200 W panel, so extra panel watts are clipped. Expect about 0.7 days of 5-hour sun to refill it. Panels are assumed to deliver 75% of their rating.
How heavy is the EcoFlow TRAIL 300 DC?
5.69 lb (2.58 kg). That is about 51 Wh per pound.
