Frequently Asked Questions

Common questions asked by campers, vanlifers, and emergency preppers.

Can the Oupes Mega 2 Portable Power Station run a medical CPAP machine?

Yes. With 2048Wh of rated battery capacity, the Oupes Mega 2 Portable Power Station can power a standard CPAP machine (consuming 30W to 45W without heated humidifier) for approximately 44 to 58 hours, providing multiple nights of quiet off-grid sleep.

Does the Oupes Mega 2 Portable Power Station have a pure sine wave inverter?

Yes. In our laboratory oscilloscope testing, the Oupes Mega 2 Portable Power Station delivered a true pure sine wave AC output with Total Harmonic Distortion (THD) under 2.5%, making it completely safe for sensitive laptops, drone chargers, and medical equipment.

What is the real-world battery lifespan of the Oupes Mega 2 Portable Power Station?

The Oupes Mega 2 Portable Power Station utilizes premium LiFePO4 battery cells engineered for 3500 full charge/discharge cycles before degrading to 80% original capacity. Under daily use, this equates to roughly 8 to 10 years of reliable service.
