OUPES Mega 1 Review: Solid Power Station with USB-C Issues“this power station has plenty of power to give 2,000 Watts that's a lot to provide out these AC ports and with 1,24 wat hours and the option to expand that this thing would be pretty good for camping for Van living for emergency backup at home”Open at 19:24

Runtime predictions for your loads
Based on 1,024 Wh capacity · 95% LiFePO4 DoD · 90% AC inverter efficiency. Phase-1 uses constant-load math; time-resolved multi-day SOC simulation is the Phase-2 north star.
| Load profile | Continuous draw | Runtime estimate |
|---|---|---|
| CPAP only (overnight) | 60W | 14.6 hr |
| Fridge only (cycle-averaged) | 70W | 12.5 hr |
| Wifi router + LED lights | 55W | 15.9 hr |
| Your full continuous load (215W) | 215W | 4.1 hr |
| Microwave + base load (peak) | 1300W | 40 min |
| Window AC 8,000 BTU (avg) | 700W | 1.3 hr |
Detailed specs
Sourced from manufacturer datasheet · verified 1mo agoFor advanced shoppers. Plug types matter if you have a 30A RV; MPPT range matters if you plan custom solar arrays.
Battery behavior
| Cell chemistry | LiFePO4 |
| Cycle life @ 80% capacity | 3,500 |
| Parasitic loss (idle, AC off) | pending verification |
Why parasitic loss matters: for store-and-forget hurricane prep, even ~2W idle drain adds up — a fully charged unit can drain in months sitting in a closet.
