Design
The OUPES Mega I’s rugged build and high-capacity battery make it a standout for outdoor and emergency use, much like other leading models in the portable power station market. With a matte-black finish, rubberized corners, and a compact rectangular profile, it blends well into camping setups and emergency storage areas. The build quality feels premium for its price range, and it won’t look out of place in your garage.
A clear LCD display on the front panel shows battery percentage, power draw, and charging status, keeping the interface informative without sacrificing durability.
It’s designed for plug-and-play simplicity, with individual power section buttons and an IoT connectivity switch located on the front panel, plus dual carrying handles for two-handed transport.
Dimensions and Build
- Width: 14.7 inches
- Height: 9.8 inches
- Depth: 12.5 inches
- Weight: Approximately 28 lbs
Its compact size makes it perfect for RV storage, camping trips, or emergency backup scenarios. It can handle outdoor conditions but is light enough for reasonable portability between locations.
Performance
Power Output
The standout feature of The OUPES Mega I is its genuine 2000W continuous output. When activated, it can run serious appliances like refrigerators, power tools, and multiple devices simultaneously. Users who struggle with underpowered alternatives will find this a significant step up from smaller power banks.
Efficiency and Runtime
Testing shows 79% efficiency under heavy loads (1779W), running for 27 minutes versus an expected 34 minutes. While not perfect, it’s respectable for this price range. The unit automatically shuts down at 2% battery to preserve cooling fan operation—a smart thermal protection feature.
Charging
Fast AC Charging
- 1,400 W for a full charge in about 1.3 hours
- 700 W for a full charge in about 2.6 hours
Solar Charging
- 800 W max, resulting in a full charge in around 2.2 hours
Combined AC + Solar Input
- Up to 2,200 W combined, enabling a full recharge in approximately 1 hour
Connectivity Options
- Bluetooth and Wi-Fi – Connect via the OUPES app for remote monitoring
- 800W Solar Input – Anderson connector for standard solar panels
- AC Input – Proprietary connector for wall charging.
- Car Charging – 12V input for vehicle charging.
- No HDMI or Advanced Connectivity – This is a power station, not an entertainment device
The absence of standard charging cables is the biggest limitation, as losing the proprietary AC adapter makes wall charging impossible.
Ease of Use
The setup is straightforward: connect your devices, turn on the appropriate power section, and monitor via the LCD display. The controls are intuitive:
- Power section switches – These physical buttons activate different output groups—AC, DC, or USB—allowing you to turn on only what you need and save power.
- Battery percentage display – Shows the exact remaining battery capacity as a percentage, helping you plan usage and charging intervals.
- Real-time power draw monitoring – Displays the current wattage being consumed by connected devices, so you can avoid overloads and track efficiency.
