The 300Wh Power Station That Doesn't Flinch at 700 Watts.
DPS-350D packs 297.6Wh of LiFePO4 capacity into a 3.2 kg frame — with a 700W peak AC output that starts motor loads, compressor fridges, and power tools that choke out every other unit in this weight class.
The 700W Problem: Why "300Wh Capacity" Is Only Half the Story
Most power station specs skip the critical detail: peak wattage versus continuous rating.Continuous wattage is what the unit sustains. Peak wattage is what it can start. Compressor motors in car fridges, portable AC units, and air compressors demand 2–3× their running wattage at startup. A 300W continuous unit maxing out at 300–400W peak will trip protection the moment you power up a compressor fridge.The DPS-350D delivers 350W continuous and 700W peak — the highest peak-to-continuous ratio in its class. That's why overlanders choose it. They've learned that undersized peak ratings mean a dead unit when you need it most.
