How long will a portable power station actually run a refrigerator during a power outage? In this video I put the new OUPES Mega 1 Lite to a real-world fridge test. I unplugged my refrigerator from the wall and ran it entirely from the Mega 1 Lite. After 7 hours of continuous operation the battery still had 10% remaining.
Along with the fridge runtime test, I compare the Mega 1 Lite to the original OUPES Mega 1 so you can see what changed and decide which unit fits your needs. OUPES built the Mega 1 Lite to be smaller, lighter and more affordable than the original. It keeps the same 1024Wh capacity and 2000W output but drops the expansion battery support. If you want a simple home backup power station for a refrigerator, CPAP, laptop, or ham radio station, and you don’t need to add batteries later, the Lite may be the better value.
OUPES Mega 1 Lite key specs:
• 1024Wh LiFePO4 (LFP) battery rated for 3,500+ cycles to 80% capacity
• 2000W continuous pure sine wave AC output, 4500W surge
• 4 AC outlets, 2 USB-C PD (140W each), 2 USB-A, 12V car port
• 1400W AC fast charging, about 46 minutes to full
• 800W solar input (12 to 78V DC, MPPT), about 69 minutes to full in ideal sun
• Up to 2200W combined AC plus solar charging
• UPS switchover under 20ms for CPAP machines, computers and networking gear
• Pass-through charging
• Cleanergy app control over WiFi or Bluetooth with OTA firmware updates
• 26.8 lb, 15.1 x 9.1 x 11.6 inches
Why a fridge test? The refrigerator is usually the first thing people want to keep running in a blackout, and it’s one of the harder loads for a portable power station. The compressor cycles on and off and pulls a startup surge each time it kicks on. Real-world runtime numbers like these will tell you more than a spec sheet when you’re planning emergency backup power for your home, RV, camper or off-grid setup.
If you’re into emergency communications, ARES, POTA, or preparedness, a LiFePO4 solar generator like the Mega 1 Lite can also run your radios, charge handhelds, and keep your station on the air when the grid goes down.
