The EcoFlow TRAIL Plus 300 DC is a 288 Wh outdoor power station that hides two useful extras inside a very slim 20.6 x 11.5 x 2.3 cm chassis: a detachable handle that also works as a 140 W USB-C charging cable, and a built-in lamp for camp use. It weighs 2.26 kg, runs on NCM (Li-Ion) cells and puts out 300 W total DC power across six ports, including three 140 W USB-C ports for parallel laptop charging. Like the TRAIL 300 DC it has a Solar/Auto input for an 11-30 V solar panel up to 110 W or a 12 V car charger for on-the-road top-ups.
